[76 FR 12451, Mar. 7, 2011; 76 FR 24763, May 2, 2011] ## §429.16 Central air conditioners and central air conditioning heat pumps.(a) Determination of Represented Value—(1) Required represented values. Determine the represented values (including SEER, EER, HSPF, SEER2, EER2, HSPF2, PW,OFF, cooling capacity, and heating capacity, as applicable) for the individual models/combinations (or “tested combinations”) specified in the following table.
(2) PW,OFF. If individual models of single-package systems or individual combinations (or “tested combinations”) of split systems that are otherwise identical are offered with multiple options for off mode-related components, determine the represented value for the individual model/combination with the crankcase heater and controls that are the most consumptive. A manufacturer may also determine represented values for individual models/combinations with less consumptive off mode options; however, all such options must be identified with different model numbers for single-package systems or for outdoor units (in the case of split systems). (3) Refrigerants. (i) If a model of outdoor unit (used in a single-split, multi-split, multi-circuit, multi-head mini-split, and/or outdoor unit with no match system) is distributed in commerce and approved for use with multiple refrigerants, a manufacturer must determine all represented values for that model using each refrigerant that can be used in an individual combination of the basic model (including outdoor units with no match or “tested combinations”). This requirement may apply across the listed categories in the table in paragraph (a)(1) of this section. A refrigerant is considered approved for use if it is listed on the nameplate of the outdoor unit. If any of the refrigerants approved for use is HCFC-22 or has a 95 °F midpoint saturation absolute pressure that is ± 18 percent of the 95 °F saturation absolute pressure for HCFC-22, or if there are no refrigerants designated as approved for use, a manufacturer must determine represented values (including SEER, EER, HSPF, SEER2, EER2, HSPF2, PW,OFF, cooling capacity, and heating capacity, as applicable) for, at a minimum, an outdoor unit with no match. If a model of outdoor unit is not charged with a specified refrigerant from the point of manufacture or if the unit is shipped requiring the addition of more than two pounds of refrigerant to meet the charge required for testing per section 2.2.5 of appendix M or appendix M1 (unless either (a) the factory charge is equal to or greater than 70% of the outdoor unit internal volume times the liquid density of refrigerant at 95 °F or (b) an A2L refrigerant is approved for use and listed in the certification report), a manufacturer must determine represented values (including SEER, EER, HSPF, SEER2, EER2, HSPF2, PW,OFF, cooling capacity, and heating capacity, as applicable) for, at a minimum, an outdoor unit with no match. (ii) If a model is approved for use with multiple refrigerants, a manufacturer may make multiple separate representations for the performance of that model (all within the same individual combination or outdoor unit with no match) using the multiple approved refrigerants. In the alternative, manufacturers may certify the model (all within the same individual combination or outdoor unit with no match) with a single representation, provided that the represented value is no more efficient than its performance using the least-efficient refrigerant. If a manufacturer certifies a single model with multiple representations for the different approved refrigerants, it may use an AEDM to determine the represented values for all other refrigerants besides the refrigerant used for testing. A single representation made for multiple refrigerants may not include equipment in multiple categories or equipment subcategories listed in the table in paragraph (a)(1) of this section. (4) Limitations for represented values of individual combinations. The following paragraphs explains the limitations for represented values of individual combinations (or “tested combinations”). (i) Regional. A basic model may only be certified as compliant with a regional standard if all individual combinations within that basic model meet the regional standard for which it is certified. A model of outdoor unit that is certified below a regional standard can only be rated and certified as compliant with a regional standard if the model of outdoor unit has a unique model number and has been certified as a different basic model for distribution in each region. An ICM cannot certify an individual combination with a rating that is compliant with a regional standard if the individual combination includes a model of outdoor unit that the OUM has certified with a rating that is not compliant with a regional standard. Conversely, an ICM cannot certify an individual combination with a rating that is not compliant with a regional standard if the individual combination includes a model of outdoor unit that an OUM has certified with a rating that is compliant with a regional standard. (ii) Multiple product classes. Models of outdoor units that are rated and distributed in individual combinations that span multiple product classes must be tested, rated, and certified pursuant to paragraph (a) of this section as compliant with the applicable standard for each product class. This includes multi-split systems, multi-circuit systems, and multi-head mini-split systems with a represented value for a mixed combination including both SDHV and either non-ducted or ducted indoor units. (5) Requirements. All represented values under paragraph (a) of this section must be based on testing in accordance with the requirements in paragraph (b) of this section or the application of an AEDM or other methodology as allowed in paragraph (c) of this section. (b) Units tested—(1) General. The general requirements of §429.11 apply to central air conditioners and heat pumps; and (2) Individual model/combination selection for testing. (i) The table identifies the minimum testing requirements for each basic model that includes multiple individual models/combinations; if a basic model spans multiple categories or subcategories listed in the table, multiple testing requirements apply. For each basic model that includes only one individual model/combination, test that individual model/combination. For single-split-system non-space-constrained air conditioners and heat pumps, when testing is required in accordance with 10 CFR part 430, subpart B, appendix M1, these requirements do not apply until July 1, 2024, provided that the manufacturer is certifying compliance of all basic models using an AEDM in accordance with paragraph (c)(1)(i)(B) of this section and paragraph (e)(2)(i)(A) of §429.70.
(ii) Each individual model/combination (or “tested combination”) identified in paragraph (b)(2)(i) of this section is not required to be tested for PW,OFF. Instead, at a minimum, among individual models/combinations with similar off-mode construction (even spanning different models of outdoor units), a manufacturer must test at least one individual model/combination for PW,OFF. (3) Sampling plans and represented values. For individual models (for single-package systems) or individual combinations (for split-systems, including “tested combinations” for multi-split, multi-circuit, and multi-head mini-split systems) with represented values determined through testing, each individual model/combination (or “tested combination”) must have a sample of sufficient size tested in accordance with the applicable provisions of this subpart. For heat pumps (other than heating-only heat pumps), all units of the sample population must be tested in both the cooling and heating modes and the results used for determining all representations. The represented values for any individual model/combination must be assigned such that: (i) Off-Mode. Any represented value of power consumption or other measure of energy consumption for which consumers would favor lower values must be greater than or equal to the higher of: (A) The mean of the sample, where:
and, x is the sample mean; n is the number of samples; and xi is the ith sample; Or, (B) The upper 90 percent confidence limit (UCL) of the true mean divided by 1.05, where:
And x is the sample mean; s is the sample standard deviation; n is the number of samples; and t0.90 is the t statistic for a 90 percent one-tailed confidence interval with n−1 degrees of freedom (from appendix D). Round represented values of off-mode power consumption to the nearest watt. (ii) SEER, EER, HSPF, SEER2, EER2, and HSPF2. Any represented value of the energy efficiency or other measure of energy consumption for which consumers would favor higher values shall be less than or equal to the lower of: (A) The mean of the sample, where:
and, x̅ is the sample mean; n is the number of samples; and xi is the ith sample; or, (B) The lower 90 percent confidence limit (LCL) of the true mean divided by 0.95, where:
And x̅ is the sample mean; s is the sample standard deviation; n is the number of samples; and t0.90 is the t statistic for a 90 percent one-tailed confidence interval with n-1 degrees of freedom (from appendix D). Round represented values of EER, SEER, HSPF, EER2, SEER2, and HSPF2 to the nearest 0.05. (iii) Cooling Capacity and Heating Capacity. The represented values of cooling capacity and heating capacity must each be a self-declared value that is: (A) Less than or equal to the lower of: (1) The mean of the sample, where:
and, x̅ is the sample mean; n is the number of samples; and xi is the ith sample; or, (2) The lower 90 percent confidence limit (LCL) of the true mean divided by 0.95, where:
And x̅ is the sample mean; s is the sample standard deviation; n is the number of samples; and t0.90 is the t statistic for a 90 percent one-tailed confidence interval with n-1 degrees of freedom (from appendix D). (B) Rounded according to: (1) To the nearest 100 Btu/h if cooling capacity or heating capacity is less than 20,000 Btu/h, (2) To the nearest 200 Btu/h if cooling capacity or heating capacity is greater than or equal to 20,000 Btu/h but less than 38,000 Btu/h, and (3) To the nearest 500 Btu/h if cooling capacity or heating capacity is greater than or equal to 38,000 Btu/h and less than 65,000 Btu/h. (c) Determination of represented values for all other individual models/combinations besides those specified in paragraph (b)(2) of this section—(1) All basic models except outdoor units with no match and multi-split systems, multi-circuit systems, and multi-head mini-split systems. (i) For every individual model/combination within a basic model other than the individual model/combination required to be tested pursuant to paragraph (b)(2) of this section, either— (A) A sample of sufficient size, comprised of production units or representing production units, must be tested as complete systems with the resulting represented values for the individual model/combination obtained in accordance with paragraphs (b)(1) and (3) of this section; or (B) The represented values of the measures of energy efficiency or energy consumption through the application of an AEDM in accordance with paragraph (d) of this section and §429.70. An AEDM may only be used to determine represented values for individual models or combinations in a basic model (or separate approved refrigerants within an individual combination) other than the individual model or combination(s) required for mandatory testing under paragraph (b)(2) of this section, except that, for single-split, non-space-constrained systems, when testing is required in accordance with 10 CFR part 430, subpart B, appendix M1, an AEDM may be used to rate the individual model or combination(s) required for mandatory testing under paragraph (b)(2) of this section until July 1, 2024, in accordance with paragraph (e)(2)(i)(A) of §429.70. (ii) For every individual model/combination within a basic model tested pursuant to paragraph (b)(2) of this section, but for which PW,OFF testing was not conducted, the represented value of PW,OFF may be assigned through, either: (A) The testing result from an individual model/combination of similar off-mode construction, or (B) The application of an AEDM in accordance with paragraph (d) of this section and §429.70. (2) Outdoor units with no match. All models of outdoor units with no match within a basic model must be tested. No model of outdoor unit with no match may be rated with an AEDM, other than to determine the represented values for models using approved refrigerants other than the one used in testing. (3) For multi-split systems, multi-circuit systems, and multi-head mini-split systems. The following applies: (i) When testing in accordance with 10 CFR part 430, subpart B, appendix M1, for basic models that include additional varieties of ducted indoor units (i.e., conventional, low-static, or mid-static) other than the one for which representation is required in paragraph (a)(1) of this section, if a manufacturer chooses to make a representation, the manufacturer must conduct testing of a tested combination according to the requirements in paragraph (b)(3) of this section. (ii) When testing in accordance with 10 CFR part 430, subpart B, appendix M, for basic models composed of both non-ducted and ducted combinations, the represented value for the mixed non-ducted/ducted combination is the mean of the represented values for the non-ducted and ducted combinations as determined in accordance with paragraph (b)(3) of this section. When testing in accordance with 10 CFR part 430, subpart B, appendix M1, for basic models that include mixed combinations of indoor units (any two kinds of non-ducted, low-static, mid-static, and conventional ducted indoor units), the represented value for the mixed combination is the mean of the represented values for the individual component combinations as determined in accordance with paragraph (b)(3) of this section. (iii) When testing in accordance with 10 CFR part 430, subpart B, appendix M, for basic models composed of both SDHV and non-ducted or ducted combinations, the represented value for the mixed SDHV/non-ducted or SDHV/ducted combination is the mean of the represented values for the SDHV, non-ducted, or ducted combinations, as applicable, as determined in accordance with paragraph (b)(3) of this section. When testing in accordance with 10 CFR part 430, subpart B, appendix M1, for basic models including mixed combinations of SDHV and another kind of indoor unit (any of non-ducted, low-static, mid-static, and conventional ducted), the represented value for the mixed SDHV/other combination is the mean of the represented values for the SDHV and other tested combination as determined in accordance with paragraph (b)(3) of this section. (iv) All other individual combinations of models of indoor units for the same model of outdoor unit for which the manufacturer chooses to make representations must be rated as separate basic models, and the provisions of paragraphs (b)(1) through (3) and (c)(3)(i) through (iii) of this section apply. (v) With respect to PW,OFF only, for every individual combination (or “tested combination”) within a basic model tested pursuant to paragraph (b)(2) of this section, but for which PW,OFF testing was not conducted, the representative values of PW,OFF may be assigned through either: (A) The testing result from an individual model or combination of similar off-mode construction, or (B) Application of an AEDM in accordance with paragraph (d) of this section and §429.70. (d) Alternative efficiency determination methods. In lieu of testing, represented values of efficiency or consumption may be determined through the application of an AEDM pursuant to the requirements of §429.70(e) and the provisions of this section.

(b) [Reserved] [82 FR 1099, Jan. 4, 2017] ## §429.70 Alternative methods for determining energy efficiency and energy use.(a) General applicability of an AEDM. A manufacturer of covered products or covered equipment explicitly authorized to use an AEDM in §§429.14 through 429.62 may not distribute any basic model of such equipment in commerce unless the manufacturer has determined the energy efficiency of the basic model, either from testing the basic model in conjunction with DOE's certification sampling plans and statistics or from applying an alternative method for determining energy efficiency or energy use (AEDM) to the basic model, in accordance with the requirements of this section. In instances where a manufacturer has tested a basic model, the manufacturer may not knowingly use an AEDM to overrate the efficiency (or underrate the consumption) of the model. (b) Testing. Testing for each covered product or covered equipment must be done in accordance with the sampling plan provisions established in §429.11 and the testing procedures in parts 430 and 431 of this chapter. (c) Alternative efficiency determination method (AEDM) for commercial HVAC (includes commercial warm air furnaces and commercial packaged boilers), WH, and refrigeration equipment—(1) Criteria an AEDM must satisfy. A manufacturer may not apply an AEDM to a basic model to determine its efficiency pursuant to this section unless: (i) The AEDM is derived from a mathematical model that estimates the energy efficiency or energy consumption characteristics of the basic model as measured by the applicable DOE test procedure; (ii) The AEDM is based on engineering or statistical analysis, computer simulation or modeling, or other analytic evaluation of performance data; and (iii) The manufacturer has validated the AEDM, in accordance with paragraph (c)(2) of this section with basic models that meet the current Federal energy conservation standards. (2) Validation of an AEDM. Before using an AEDM, the manufacturer must validate the AEDM's accuracy and reliability as follows: (i) The manufacturer must select at least the minimum number of basic models for each validation class specified in paragraph (c)(2)(iv) of this section to which the particular AEDM applies. Using the AEDM, calculate the energy use or efficiency for each of the selected basic models. Test a single unit of each selected basic model in accordance with paragraph (c)(2)(iii) of this section. Compare the results from the single unit test and the AEDM energy use or efficiency output according to paragraph (c)(2)(ii) of this section. The manufacturer is responsible for ensuring the accuracy and reliability of the AEDM. (ii) Individual model tolerances. (A) For those covered products with an energy-efficiency metric, the predicted efficiency for each model calculated by applying the AEDM may not be more than five percent greater than the efficiency determined from the corresponding test of the model. (B) For those covered products with an energy-consumption metric, the predicted energy consumption for each model, calculated by applying the AEDM, may not be more than five percent less than the energy consumption determined from the corresponding test of the model. (C) For all covered products, the predicted energy efficiency or consumption for each model calculated by applying the AEDM must meet or exceed the applicable federal energy conservation performance standard. (D) An AEDM that is validated based on test results obtained from one or more field tests (pursuant to §431.86(c)) can only be used to certify the performance of basic models of commercial packaged boilers with a certified rated input greater than 5,000,000 Btu/h. (iii) Additional test unit requirements. (A) Each AEDM must be supported by test data obtained from physical tests of current models; and (B) Test results used to validate the AEDM must meet or exceed current, applicable Federal standards as specified in part 431 of this chapter; and (C) Each test must have been performed in accordance with the DOE test procedure specified in parts 430 or 431 of this chapter or test procedure waiver for which compliance is required at the time the basic model is distributed in commerce. (iv) Validation classes.
(3) AEDM records retention requirements. If a manufacturer has used an AEDM to determine representative values pursuant to this section, the manufacturer must have available upon request for inspection by the Department records showing: (i) The AEDM, including the mathematical model, the engineering or statistical analysis, and/or computer simulation or modeling that is the basis of the AEDM; (ii) Product information, complete test data, AEDM calculations, and the statistical comparisons from the units tested that were used to validate the AEDM pursuant to paragraph (c)(2) of this section; and (iii) Product information and AEDM calculations for each basic model to which the AEDM has been applied. (4) Additional AEDM requirements. If requested by the Department and at DOE's discretion, the manufacturer must perform at least one of the following: (i) Conduct simulations before representatives of the Department to predict the performance of particular basic models of the product to which the AEDM was applied; (ii) Provide analyses of previous simulations conducted by the manufacturer; or (iii) Conduct certification testing of basic models selected by the Department. (5) AEDM verification testing. DOE may use the test data for a given individual model generated pursuant to §429.104 to verify the certified rating determined by an AEDM as long as the following process is followed: (i) Selection of units. DOE will obtain units for test from retail, where available. If units cannot be obtained from retail, DOE will request that a unit be provided by the manufacturer; (ii) Lab requirements. DOE will conduct testing at an independent, third-party testing facility of its choosing. In cases where no third-party laboratory is capable of testing the equipment, it may be tested at a manufacturer's facility upon DOE's request. (iii) Manufacturer participation. (A) Except when testing variable refrigerant flow systems (which are governed by the rules found at §431.96(f)), testing will be completed without a manufacturer representative on-site. In limited instances further described in paragraph (c)(5)(iii)(B) of this section, a manufacturer and DOE representative may be present to witness the test set-up. (B) A manufacturer's representative may request to be on-site to witness the test set-up if: (1) The installation manual for the basic model specifically requires it to be started only by a factory-trained installer; or (2) The manufacturer has elected, as part of the certification of that basic model, to have the opportunity to witness the test set-up. A manufacturer may elect to witness the test set-up for the initial verification test for no more than 10 percent of the manufacturer's basic models submitted for certification and rated with an AEDM per validation class specified in section (c)(2)(iv) of this paragraph. The 10-percent limit applies to all of the eligible basic models submitted for certification by a given manufacturer no matter how many AEDMs a manufacturer has used to develop its ratings. The 10-percent limit is determined by first calculating 10 percent of the total number of basic models rated with an AEDM per validation class, and then truncating the resulting product. Manufacturers who have submitted fewer than 10 basic models rated with an AEDM for certification may elect to have the opportunity to witness the test set-up of one basic model. A manufacturer must identify the basic models it wishes to witness as part of its certification report(s) prior to the basic model being selected for verification testing. (3) In those instances in which a manufacturer has not provided the required information as specified in §429.12(b)(13) for a given basic model that has been rated and certified as compliant with the applicable standards, a manufacturer is precluded from witnessing the testing set up for that basic model. (C) A DOE representative will be present for the test set-up in all cases where a manufacturer representative requests to be on-site for the test set-up. The manufacturer's representative cannot communicate with a lab representative outside of the DOE representative's presence. (D) If DOE has obtained through retail channels a unit for test that meets either of the conditions in paragraph (c)(5)(iii)(B) of this section, DOE will notify the manufacturer that the basic model was selected for testing and that the manufacturer may have a representative present for the test set-up. If the manufacturer does not respond within five calendar days of receipt of that notification, the manufacturer waives the option to be present for test set-up, and DOE will proceed with the test set-up without a manufacturer's representative present. (E) If DOE has obtained directly from the manufacturer a unit for test that meets either of the conditions in paragraph (c)(5)(iii)(B) of this section, DOE will notify the manufacturer of the option to be present for the test set-up at the time the unit is purchased. DOE will specify the date (not less than five calendar days) by which the manufacturer must notify DOE whether a manufacturer's representative will be present. If the manufacturer does not notify DOE by the date specified, the manufacturer waives the option to be present for the test set-up, and DOE will proceed with the test set-up without a manufacturer's representative present. (F) DOE will review the certification submissions from the manufacturer that were on file as of the date DOE purchased a basic model (under paragraph (c)(5)(iii)(D) of this section) or the date DOE notifies the manufacturer that the basic model has been selected for testing (under paragraph (c)(5)(iii)(E) of this section) to determine if the manufacturer has indicated that it intends to witness the test set-up of the selected basic model. DOE will also verify that the manufacturer has not exceeded the allowable limit of witness testing selections as specified in paragraph (c)(5)(iii)(B)(2) of this section. If DOE discovers that the manufacturer exceeded the limits specified in paragraph (c)(5)(iii)(B)(2), DOE will notify the manufacturer of this fact and deny its request to be present for the test set-up of the selected basic model. The manufacturer must update its certification submission to ensure it has not exceeded the allowable limit of witness testing selections as specified in paragraph (c)(5)(iii)(B)(2) to be present at set-up for future selections. At this time DOE will also review the supplemental PDF submission(s) for the selected basic model to determine that all necessary information has been provided to the Department. (G) If DOE determines, pursuant to paragraph (c)(5)(ii) of this section, that the model should be tested at the manufacturer's facility, a DOE representative will be present on site to observe the test set-up and testing with the manufacturer's representative. All testing will be conducted at DOE's direction, which may include DOE-contracted personnel from a third-party lab, as well as the manufacturer's technicians. (H) As further explained in paragraph (c)(5)(v)(B) of this section, if a manufacturer's representative is present for the initial test set-up for any reason, the manufacturer forfeits any opportunity to request a retest of the basic model. Furthermore, if the manufacturer requests to be on-site for test set-up pursuant to paragraph (c)(5)(iii)(B) of this section but is not present on site, the manufacturer forfeits any opportunity to request a retest of the basic model. (iv) Testing. At no time during verification testing may the lab and the manufacturer communicate without DOE authorization. All verification testing will be conducted in accordance with the applicable DOE test procedure, as well as each of the following to the extent that they apply: (A) Any active test procedure waivers that have been granted for the basic model; (B) Any test procedure guidance that has been issued by DOE; (C) The installation and operations manual that is shipped with the unit; (D) Any additional information that was provided by the manufacturer at the time of certification (prior to DOE obtaining the unit for test); and (E) If during test set-up or testing, the lab indicates to DOE that it needs additional information regarding a given basic model in order to test in accordance with the applicable DOE test procedure, DOE may organize a meeting between DOE, the manufacturer and the lab to provide such information. (v) Failure to meet certified rating. If a model tests worse than its certified rating by an amount exceeding the tolerance prescribed in paragraph (c)(5)(vi) of this section, DOE will notify the manufacturer. DOE will provide the manufacturer with all documentation related to the test set up, test conditions, and test results for the unit. Within the timeframe allotted by DOE, the manufacturer may then: (A) Present all claims regarding testing validity; and (B) If the manufacturer was not on site for the initial test set-up, request a retest of the previously tested unit with manufacturer and DOE representatives on-site for the test set-up. DOE will not conduct the retest using a different unit of the same basic model unless DOE and the manufacturer determine it is necessary based on the test results, claims presented, and DOE regulations. (vi) Tolerances. (A) For consumption metrics, the result from a DOE verification test must be less than or equal to the certified rating × (1 + the applicable tolerance). (B) For efficiency metrics, the result from a DOE verification test must be greater than or equal to the certified rating × (1 − the applicable tolerance).
(vii) Invalid rating. If, following discussions with the manufacturer and a retest where applicable, DOE determines that the verification testing was conducted appropriately in accordance with the DOE test procedure, DOE will issue a determination that the rating for the model is invalid. The manufacturer must elect, within 15 days, one of the following to be completed in a time frame specified by DOE, which is never to exceed 180 days: (A) Re-rate and re-certify the model based on DOE's test data alone; or (B) Discontinue the model through the certification process; or (C) Conduct additional testing and re-rate and re-certify the basic model based on all test data collected, including DOE's test data. (viii) AEDM use. (A) If DOE has determined that a manufacturer made invalid ratings on two or more models rated using the same AEDM within a 24 month period, the manufacturer must take the action listed in the table corresponding to the number of invalid certified ratings. The twenty-four month period begins with a DOE determination that a rating is invalid through the process outlined above. Additional invalid ratings apply for the purposes of determining the appropriate consequences if the subsequent determination(s) is based on selection of a unit for testing within the twenty-four month period (i.e., subsequent determinations need not be made within 24 months).
(B) If, as a result of eight or more invalid ratings, a manufacturer has lost the privilege of using an AEDM for rating, the manufacturer may regain the ability to use an AEDM by: (1) Investigating and identifying cause(s) for failures; (2) Taking corrective action to address cause(s); (3) Performing six new tests per validation class, a minimum of two of which must be performed by an independent, third-party laboratory to validate the AEDM; and (4) Obtaining DOE authorization to resume use of the AEDM. (d) Alternative efficiency determination method for distribution transformers—A manufacturer may use an AEDM to determine the efficiency of one or more of its untested basic models only if it determines the efficiency of at least five of its other basic models (selected in accordance with paragraph (d)(3) of this section) through actual testing. (1) Criteria an AEDM must satisfy. (i) The AEDM has been derived from a mathematical model that represents the electrical characteristics of that basic model; (ii) The AEDM is based on engineering and statistical analysis, computer simulation or modeling, or other analytic evaluation of performance data; and (iii) The manufacturer has substantiated the AEDM, in accordance with paragraph (d)(2) of this section, by applying it to, and testing, at least five other basic models of the same type, i.e., low-voltage dry-type distribution transformers, medium-voltage dry-type distribution transformers, or liquid-immersed distribution transformers. (2) Substantiation of an AEDM. Before using an AEDM, the manufacturer must substantiate the AEDM's accuracy and reliability as follows: (i) Apply the AEDM to at least five of the manufacturer's basic models that have been selected for testing in accordance with paragraph (d)(3) of this section, and calculate the power loss for each of these basic models; (ii) Test at least five units of each of these basic models in accordance with the applicable test procedure and §429.47, and determine the power loss for each of these basic models; (iii) The predicted total power loss for each of these basic models, calculated by applying the AEDM pursuant to paragraph (d)(2)(i) of this section, must be within plus or minus five percent of the mean total power loss determined from the testing of that basic model pursuant to paragraph (d)(2)(ii) of this section; and (iv) Calculate for each of these basic models the percentage that its power loss calculated pursuant to paragraph (d)(2)(i) of this section is of its power loss determined from testing pursuant to paragraph (d)(2)(ii) of this section, compute the average of these percentages, and that calculated average power loss, expressed as a percentage of the average power loss determined from testing, must be no less than 97 percent and no greater than 103 percent. (3) Additional testing requirements.

A manufacturer may not apply an AEDM to an individual model/combination to determine its represented values (SEER, EER, HSPF, SEER2, EER2, HSPF2, and/or PW,OFF) pursuant to this section unless authorized pursuant to §429.16(d) and: (i) The AEDM is derived from a mathematical model that estimates the energy efficiency or energy consumption characteristics of the individual model or combination (SEER, EER, HSPF, SEER2, EER2, HSPF2, and/or PW,OFF) as measured by the applicable DOE test procedure; and (ii) The manufacturer has validated the AEDM in accordance with paragraph (e)(2) of this section. (2) Validation of an AEDM. Before using an AEDM, the manufacturer must validate the AEDM's accuracy and reliability as follows: (i) Follow paragraph (e)(2)(i)(A) of this section for requirements on minimum testing. Follow paragraph (e)(2)(i)(B) of this section for requirements on ensuring the accuracy and reliability of the AEDM. (A) Minimum testing. (1) For non-space-constrained single-split system air conditioners and heat pumps rated based on testing in accordance with appendix M to subpart B of part 430, the manufacturer must test each basic model as required under §429.16(b)(2). Until July 1, 2024, for non-space-constrained single-split-system air conditioners and heat pumps rated based on testing in accordance with appendix M1 to subpart B of part 430, the manufacturer must test a single-unit sample from 20 percent of the basic models distributed in commerce to validate the AEDM. On or after July 1, 2024, for non-space-constrained single-split-system air conditioners and heat pumps rated based on testing in accordance with appendix M1 to subpart B of part 430, the manufacturer must complete testing of each basic model as required under §429.16(b)(2). (2) For other than non-space-constrained single-split-system air conditioners and heat pumps, the manufacturer must test each basic model as required under §429.16(b)(2). (B) Using the AEDM, calculate the energy use or efficiency for each of the tested individual models/combinations within each basic model. Compare the represented value based on testing and the AEDM energy use or efficiency output according to paragraph (e)(2)(ii) of this section. The manufacturer is responsible for ensuring the accuracy and reliability of the AEDM and that their representations are appropriate and the models being distributed in commerce meet the applicable standards, regardless of the amount of testing required in paragraphs (e)(2)(i)(A) and (e)(2)(i)(B) of this section. (ii) Individual model/combination tolerances. This paragraph (e)(2)(ii) provides the tolerances applicable to individual models/combinations rated using an AEDM. (A) The predicted represented values for each individual model/combination calculated by applying the AEDM may not be more than four percent greater (for measures of efficiency) or less (for measures of consumption) than the values determined from the corresponding test of the individual model/combination. (B) The predicted energy efficiency or consumption for each individual model/combination calculated by applying the AEDM must meet or exceed the applicable federal energy conservation standard. (iii) Additional test unit requirements. (A) Each AEDM must be supported by test data obtained from physical tests of current individual models/combinations; and (B) Test results used to validate the AEDM must meet or exceed current, applicable Federal standards as specified in part 430 of this chapter; and (C) Each test must have been performed in accordance with the applicable DOE test procedure with which compliance is required at the time the individual models/combinations used for validation are distributed in commerce. (3) AEDM records retention requirements. If a manufacturer has used an AEDM to determine representative values pursuant to this section, the manufacturer must have available upon request for inspection by the Department records showing: (i) The AEDM, including the mathematical model, the engineering or statistical analysis, and/or computer simulation or modeling that is the basis of the AEDM; (ii) Product information, complete test data, AEDM calculations, and the statistical comparisons from the units tested that were used to validate the AEDM pursuant to paragraph (e)(2) of this section; and (iii) Product information and AEDM calculations for each individual model/combination to which the AEDM has been applied.

If requested by the Department, the manufacturer must: (i) Conduct simulations before representatives of the Department to predict the performance of particular individual models/combinations; (ii) Provide analyses of previous simulations conducted by the manufacturer; and/or (iii) Conduct certification testing of individual models or combinations selected by the Department. (5) AEDM verification testing. DOE may use the test data for a given individual model/combination generated pursuant to §429.104 to verify the represented value determined by an AEDM as long as the following process is followed: (i) Selection of units. DOE will obtain one or more units for test from retail, if available. If units cannot be obtained from retail, DOE will request that a unit be provided by the manufacturer; (ii) Lab requirements. DOE will conduct testing at an independent, third-party testing facility of its choosing. In cases where no third-party laboratory is capable of testing the equipment, testing may be conducted at a manufacturer's facility upon DOE's request. (iii) Testing. At no time during verification testing may the lab and the manufacturer communicate without DOE authorization. If during test set-up or testing, the lab indicates to DOE that it needs additional information regarding a given individual model or combination in order to test in accordance with the applicable DOE test procedure, DOE may organize a meeting between DOE, the manufacturer and the lab to provide such information. (iv) Failure to meet certified value. If an individual model/combination tests worse than its certified value (i.e., lower than the certified efficiency value or higher than the certified consumption value) by more than 5 percent, or the test results in cooling capacity that is lower than its certified cooling capacity, DOE will notify the manufacturer. DOE will provide the manufacturer with all documentation related to the test set up, test conditions, and test results for the unit. Within the timeframe allotted by DOE, the manufacturer may present any and all claims regarding testing validity. (v) Tolerances. This paragraph specifies the tolerances DOE will permit when conducting verification testing. (A) For consumption metrics, the result from a DOE verification test must be less than or equal to 1.05 multiplied by the certified represented value. (B) For efficiency metrics, the result from a DOE verification test must be greater than or equal to 0.95 multiplied by the certified represented value. (vi) Invalid represented value.

The manufacturer must conduct additional testing and re-rate and re-certify the individual models/combinations within the basic model that were rated using the AEDM based on all test data collected, including DOE's test data. (vii) AEDM use. This paragraph (e)(5)(vii) specifies when a manufacturer's use of an AEDM may be restricted due to prior invalid represented values. (A) If DOE has determined that a manufacturer made invalid represented values on individual models/combinations within two or more basic models rated using the manufacturer's AEDM within a 24 month period, the manufacturer must test the least efficient and most efficient individual model/combination within each basic model in addition to the individual model/combination specified in §429.16(b)(2). The twenty-four month period begins with a DOE determination that a represented value is invalid through the process outlined above. (B) If DOE has determined that a manufacturer made invalid represented values on more than four basic models rated using the manufacturer's AEDM within a 24-month period, the manufacturer may no longer use an AEDM. (C) If a manufacturer has lost the privilege of using an AEDM, the manufacturer may regain the ability to use an AEDM by: (1) Investigating and identifying cause(s) for failures; (2) Taking corrective action to address cause(s); (3) Performing six new tests per basic model, a minimum of two of which must be performed by an independent, third-party laboratory from units obtained from retail to validate the AEDM; and (4) Obtaining DOE authorization to resume use of an AEDM.

Test a single unit of each basic model in accordance with paragraph (f)(2)(iii) of this section. Using the AEDM, calculate the energy use or energy efficiency for each of the selected basic models. Compare the results from the single unit test and the AEDM output according to paragraph (f)(2)(ii) of this section. The manufacturer is responsible for ensuring the accuracy and repeatability of the AEDM. (ii) Individual model tolerances. (A) The predicted efficiency for each model calculated by applying the AEDM may not be more than five percent greater than the efficiency determined from the corresponding test of the model. (B) The predicted energy efficiency for each model calculated by applying the AEDM must meet or exceed the applicable federal energy conservation standard. (iii) Additional test unit requirements. (A) Each AEDM must be supported by test data obtained from physical tests of current models; and (B) Test results used to validate the AEDM must meet or exceed current, applicable Federal standards as specified in part 431 of this chapter; (C) Each test must have been performed in accordance with the applicable DOE test procedure with which compliance is required at the time the basic model is distributed in commerce; and (D) For rating WICF refrigeration system components, an AEDM may not simulate or model portions of the system that are not required to be tested by the DOE test procedure. That is, if the test results used to validate the AEDM are for either a unit cooler only or a condensing unit only, the AEDM must estimate the system rating using the nominal values specified in the DOE test procedure for the other part of the refrigeration system. (iv) WICF refrigeration validation classes.
(3) AEDM records retention requirements. If a manufacturer has used an AEDM to determine representative values pursuant to this section, the manufacturer must have available upon request for inspection by the Department records showing: (i) The AEDM, including the mathematical model, the engineering or statistical analysis, and/or computer simulation or modeling that is the basis of the AEDM; (ii) Equipment information, complete test data, AEDM calculations, and the statistical comparisons from the units tested that were used to validate the AEDM pursuant to paragraph (f)(2) of this section; and (iii) Equipment information and AEDM calculations for each basic model to which the AEDM has been applied.

(D) At no time during the process may the lab communicate directly with the manufacturer without DOE present. (v) Failure to meet certified rating. If a model tests worse than its certified rating by an amount exceeding the tolerance prescribed in paragraph (f)(5)(vi) of this section, DOE will notify the manufacturer. DOE will provide the manufacturer with all documentation related to the test set up, test conditions, and test results for the unit. Within the timeframe allotted by DOE, the manufacturer may then present all claims regarding testing validity. (vi) Tolerances. for efficiency metrics, the result from a DOE verification test must be greater than or equal to the certified rating × (1 − the applicable tolerance).
(vii) Invalid rating. If, following discussions with the manufacturer and a retest where applicable, DOE determines that the testing was conducted appropriately in accordance with the DOE test procedure, the rating for the model will be considered invalid. Pursuant to 10 CFR 429.13(b), DOE may require a manufacturer to conduct additional testing as a remedial measure.

In addition, for commercial packaged boilers with rated input greater than 5,000,000 Btu/h, DOE, at its discretion, may allow enforcement testing of a commissioned commercial packaged boiler in the location in which it was commissioned for use, pursuant to the test provisions at §431.86(c) of this chapter, for which accreditation to ISO/IEC 17025:2005(E) would not be required. (b) Test notice. (1) To obtain units for enforcement testing to determine compliance with an applicable standard, DOE will issue a test notice addressed to the manufacturer in accordance with the following requirements: (i) DOE will send the test notice to the manufacturer's certifying official or other company official. (ii) The test notice will specify the basic model that will be selected for testing, the method of selecting the test sample, the maximum size of the sample and the size of the initial test sample, the dates at which testing is scheduled to be started and completed, and the facility at which testing will be conducted. The test notice may also provide for situations in which the selected basic model is unavailable for testing and may include alternative models or basic models. (iii) DOE will state in the test notice that it will select the units of a basic model to be tested from the manufacturer, from one or more distributors, and/or from one or more retailers. If any unit is selected from a distributor or retailer, the manufacturer shall make arrangements with the distributor or retailer for compensation for or replacement of any such units. (iv) DOE may require in the test notice that the manufacturer of a basic model ship or cause to be shipped from a retailer or distributor at its expense the requested number of units of a basic model specified in such test notice to the testing laboratory specified in the test notice. The manufacturer shall ship the specified initial test unit(s) of the basic model to the testing laboratory within 5 working days from the time units are selected. (v) If DOE determines that the units identified are low-volume or built-to-order products, DOE will contact the manufacturer to develop a plan for enforcement testing in lieu of paragraphs (ii)-(iv) of this section. (2) [Reserved] (c) Test unit selection. (1) To select units for testing from a: (i) Manufacturer's warehouse, distributor, or other facility affiliated with the manufacturer. DOE will select a batch sample at random in accordance with the provisions in paragraph (e) of this section and the conditions specified in the test notice. DOE will randomly select an initial test sample of units from the batch sample for testing in accordance with appendices A through C of this subpart. DOE will make a determination whether an alternative sample size will be used in accordance with the provisions in paragraph (e)(1)(iv) of this section. (ii) Retailer or other facility not affiliated with the manufacturer. DOE will select an initial test sample of units at random that satisfies the minimum units necessary for testing in accordance with the provisions in appendices A through C of this subpart and the conditions specified in the test notice. Depending on the results of the testing, DOE may select additional units for testing from a retailer in accordance with appendices A through C of this subpart. If the full sample is not available from a retailer, DOE will make a determination whether an alternative sample size will be used in accordance with the provisions in paragraph (e)(1)(iv) of this section. (iii) Previously commissioned commercial packaged boilers with a rated input greater than 5,000,000 Btu/h. DOE may test a sample of at least one unit in the location in which it was commissioned for use. (2) Units tested in accordance with the applicable test procedure under this part by DOE or another Federal agency, pursuant to other provisions or programs, may count toward units in the test sample. (3) The resulting test data shall constitute official test data for the basic model. Such test data will be used by DOE to make a determination of compliance or noncompliance if a sufficient number of tests have been conducted to satisfy the requirements of paragraph (e) of this section and appendices A through C of this subpart. (d) Test unit preparation. (1) Prior to and during testing, a test unit selected for enforcement testing shall not be prepared, modified, or adjusted in any manner unless such preparation, modification, or adjustment is allowed by the applicable DOE test procedure. One test shall be conducted for each test unit in accordance with the applicable test procedures prescribed in parts 430 and 431. (2) No quality control, testing or assembly procedures shall be performed on a test unit, or any parts and subassemblies thereof, that is not performed during the production and assembly of all other units included in the basic model. (3) A test unit shall be considered defective if such unit is inoperative or is found to be in noncompliance due to failure of the unit to operate according to the manufacturer's design and operating instructions. Defective units, including those damaged due to shipping or handling, shall be reported immediately to DOE. DOE may authorize testing of an additional unit on a case-by-case basis. (e) Basic model compliance. DOE will evaluate whether a basic model complies with the applicable energy conservation standard(s) based on testing conducted in accordance with the applicable test procedures specified in parts 430 and 431 of this chapter, and with the following statistical sampling procedures: (1) For products with applicable energy conservation standard(s) in §430.32 of this chapter, and commercial prerinse spray valves, illuminated exit signs, traffic signal modules and pedestrian modules, commercial clothes washers, dedicated-purpose pool pumps, and metal halide lamp ballasts, DOE will use a sample size of not more than 21 units and follow the sampling plans in appendix A of this subpart (Sampling for Enforcement Testing of Covered Consumer Products and Certain High-Volume Commercial Equipment). (2) For automatic commercial ice makers; commercial refrigerators, freezers, and refrigerator-freezers; refrigerated bottled or canned vending machines; commercial air conditioners and heat pumps; commercial packaged boilers; commercial warm air furnaces; commercial water heating equipment; and walk-in cooler and walk-in freezer refrigeration systems, DOE will use an initial sample size of not more than four units and follow the sampling plans in appendix B of this subpart (Sampling Plan for Enforcement Testing of Covered Equipment and Certain Low-Volume Covered Products). (3) If fewer than four units of a basic model are available for testing (under paragraphs (e)(1) or (2) of this section) when the manufacturer receives the notice, then: (i) DOE will test the available unit(s); or (ii) If one or more other units of the basic model are expected to become available within 30 calendar days, DOE may instead, at its discretion, test either: (A) The available unit(s) and one or more of the other units that subsequently become available (up to a maximum of four); or (B) Up to four of the other units that subsequently become available. (4) For distribution transformers, DOE will use an initial sample size of not more than five units and follow the sampling plans in appendix C of this subpart (Sampling Plan for Enforcement Testing of Distribution Transformers). If fewer than five units of a basic model are available for testing when the manufacturer receives the test notice, then: (i) DOE will test the available unit(s); or (ii) If one or more other units of the basic model are expected to become available within 30 calendar days, DOE may instead, at its discretion, test either: (A) The available unit(s) and one or more of the other units that subsequently become available (up to a maximum of five); or (B) Up to five of the other units that subsequently become available. (5) For pumps subject to the standards specified in §431.465(a) of this chapter, DOE will use an initial sample size of not more than four units and will determine compliance based on the arithmetic mean of the sample. (6) For uninterruptible power supplies, if a basic model is certified for compliance to the applicable energy conservation standard(s) in §430.32 of this chapter according to the sampling plan in §429.39(a)(2)(iv)(A) of this chapter, DOE will use a sample size of not more than 21 units and follow the sampling plan in appendix A of this subpart (Sampling for Enforcement Testing of Covered Consumer Products and Certain High-Volume Commercial Equipment). If a basic model is certified for compliance to the applicable energy conservation standard(s) in §430.32 of this chapter according to the sampling plan in §429.39(a)(2)(iv)(B) of this chapter, DOE will use a sample size of at least one unit and follow the sampling plan in appendix D of this subpart (Sampling for Enforcement Testing of Uninterruptible Power Supplies). (7) Notwithstanding paragraphs (e)(1) through (6) of this section, if testing of the available or subsequently available units of a basic model would be impractical, as for example when a basic model has unusual testing requirements or has limited production, DOE may in its discretion decide to base the determination of compliance on the testing of fewer than the otherwise required number of units. (8) When DOE makes a determination in accordance with paragraph (e)(7) of this section to test less than the number of units specified in paragraphs (e)(1) through (6) of this section, DOE will base the compliance determination on the results of such testing in accordance with appendix B of this subpart (Sampling Plan for Enforcement Testing of Covered Equipment and Certain Low-Volume Covered Products) using a sample size (n1) equal to the number of units tested. (9) For the purposes of this section, available units are those that are available for distribution in commerce within the United States.

(a) General. The following provisions apply to assessment and enforcement testing of the relevant products and equipment. (b) Refrigerators, refrigerator-freezers, and freezers— (1) Verification of total refrigerated volume. The total refrigerated volume of the basic model will be measured pursuant to the test requirements of 10 CFR part 430 for each unit tested. The results of the measurement(s) will be averaged and compared to the value of total refrigerated volume certified by the manufacturer. The certified total refrigerated volume will be considered valid only if: (i) The measurement is within two percent, or 0.5 cubic feet (0.2 cubic feet for compact products), whichever is greater, of the certified total refrigerated volume, or (ii) The measurement is greater than the certified total refrigerated volume. (A) If the certified total refrigerated volume is found to be valid, the certified adjusted total volume will be used as the basis for calculation of maximum allowed energy use for the basic model. (B) If the certified total refrigerated volume is found to be invalid, the average measured adjusted total volume, rounded to the nearest 0.1 cubic foot, will serve as the basis for calculation of maximum allowed energy use for the tested basic model. (2) Test for models with two compartments, each having its own user-operable temperature control. The test described in section 3.3 of the applicable test procedure for refrigerators or refrigerator-freezers in appendix A to subpart B of 10 CFR part 430 shall be used for all units of a tested basic model before DOE makes a determination of noncompliance with respect to the basic model. (c) Clothes washers. (1) Determination of Remaining Moisture Content. The procedure for determining remaining moisture content (RMC) will be performed once in its entirety, pursuant to the test requirements of section 3.8 of appendix J1 and appendix J2 to subpart B of part 430, for each unit tested. (i) The measured RMC value of a tested unit will be considered the tested unit's final RMC value if the measured RMC value is within two RMC percentage points of the certified RMC value of the basic model (expressed as a percentage), or is lower than the certified RMC value. (ii) If the measured RMC value of a tested unit is more than two RMC percentage points higher than the certified RMC value of the basic model, DOE will perform two additional replications of the RMC measurement procedure, each pursuant to the provisions of section 3.8.5 of appendix J1 and appendix J2 to subpart B of part 430, for a total of three independent RMC measurements of the tested unit. The average of the three RMC measurements will be the tested unit's final RMC value and will be used as the basis for the calculation of per-cycle energy consumption for removal of moisture from the test load for that unit. (2) [Reserved] (d) Residential Water Heaters and Residential-Duty Commercial Water Heaters—(1) Verification of first-hour rating and maximum GPM rating. The first-hour rating or maximum gallons per minute (GPM) rating of the basic model will be measured pursuant to the test requirements of 10 CFR part 430 for each unit tested. The mean of the measured values will be compared to the rated values of first-hour rating or maximum GPM rating as certified by the manufacturer. The certified rating will be considered valid only if the measurement is within five percent of the certified rating. (i) If the rated value of first-hour rating or maximum GPM rating is found to be within 5 percent of the mean of the measured values, then the rated value will be used as the basis for determining the applicable draw pattern pursuant to the test requirements of 10 CFR part 430 for each unit tested. (ii) If the rated value of first-hour rating or maximum GPM rating is found to vary more than 5 percent from the measured values, then the mean of the measured values will serve as the basis for determining the applicable draw pattern pursuant to the test requirements of 10 CFR part 430 for each unit tested. (2) Verification of rated storage volume. The storage volume of the basic model will be measured pursuant to the test requirements of appendix E to subpart B of 10 CFR part 430 for each unit tested. The mean of the measured values will be compared to the rated storage volume as certified by the manufacturer. The rated value will be considered valid only if the measurement is within 3 percent of the certified rating. (i) If the rated storage volume is found to be within 3 percent of the mean of the measured value of storage volume, then the rated value will be used as the basis for calculation of the required uniform energy factor for the basic model. (ii) If the rated storage volume is found to vary more than 3 percent from the mean of the measured values, then the mean of the measured values will be used as the basis for calculation of the required uniform energy factor for the basic model. (e) Packaged terminal air conditioners and packaged terminal heat pumps—(1) Verification of cooling capacity. The total cooling capacity of the basic model will be measured pursuant to the test requirements of 10 CFR part 431 for each unit tested. The results of the measurement(s) will be averaged and compared to the value of cooling capacity certified by the manufacturer. The certified cooling capacity will be considered valid only if the average measured cooling capacity is within five percent of the certified cooling capacity. (i) If the certified cooling capacity is found to be valid, that cooling capacity will be used as the basis for calculation of minimum allowed EER (and minimum allowed COP for PTHP models) for the basic model. (ii) If the certified cooling capacity is found to be invalid, the average measured cooling capacity will serve as the basis for calculation of minimum allowed EER (and minimum allowed COP for PTHP models) for the tested basic model. (2) [Reserved] (f) Dehumidifiers—(1) Verification of capacity. The capacity will be measured pursuant to the test requirements of part 430 for each unit tested. The results of the measurement(s) will be averaged and compared to the value of capacity certified by the manufacturer for the basic model. The certified capacity will be considered valid only if the measurement is within five percent, or 1.00 pint per day, whichever is greater, of the certified capacity. (i) If the certified capacity is found to be valid, the certified capacity will be used as the basis for determining the minimum energy factor or integrated energy factor allowed for the basic model. (ii) If the certified capacity is found to be invalid, the average measured capacity of the units in the sample will be used as the basis for determining the minimum energy factor or integrated energy factor allowed for the basic model. (2) Verification of whole-home dehumidifier case volume. The case volume will be measured pursuant to the test requirements of part 430 for each unit tested. The results of the measurement(s) will be averaged and compared to the value of case volume certified by the manufacturer for the basic model. The certified case volume will be considered valid only if the measurement is within two percent, or 0.2 cubic feet, whichever is greater, of the certified case volume. (i) If the certified case volume is found to be valid, the certified case volume will be used as the basis for determining the minimum integrated energy factor allowed for the basic model. (ii) If the certified case volume is found to be invalid, the average measured case volume of the units in the sample will be used as the basis for determining the minimum integrated energy factor allowed for the basic model. (g) Air-cooled small (≥65,000 Btu/h and <135,000 Btu/h), large (≥135,000 Btu/h and <240,000 Btu/h), and very large (≥240,000 Btu/h and <760,000 Btu/h) commercial package air conditioning and heating equipment—verification of cooling capacity. The cooling capacity of each tested unit of the basic model will be measured pursuant to the test requirements of part 431 of this chapter. The mean of the measurement(s) will be used to determine the applicable standards for purposes of compliance. (h) Residential boilers—test protocols for functional verification of automatic means for adjusting water temperature. These tests are intended to verify the functionality of the design requirement that a boiler has an automatic means for adjusting water temperature for single-stage, two-stage, and modulating boilers. These test methods are intended to permit the functional testing of a range of control strategies used to fulfill this design requirement. Section 2, Definitions, and paragraph 6.1.a of appendix N to subpart B of part 430 of this chapter apply for the purposes of this paragraph (h). (1) Test protocol for all products other than single-stage products employing burner delay. This test is intended to verify whether an automatic means for adjusting water temperature other than burner delay produces an incremental change in water supply temperature in response to an incremental change in inferred heat load. (i) Boiler setup—(A) Boiler installation. Boiler installation in the test room shall be in accordance with the setup and apparatus requirements of section 6 of appendix N to subpart B of 10 CFR part 430. (B) Establishing flow rate and temperature rise. Start the boiler without enabling the means for adjusting water temperature. Establish a water flow rate that allows for a water temperature rise of greater than or equal to 20 °F at maximum input rate. (C) Temperature stabilization. Temperature stabilization is deemed to be obtained when the boiler supply water temperature does not vary by more than ±3 °F over a period of five minutes. (D) Adjust the inferential load controller. (1) Adjust the boiler controls (in accordance with the I&O manual) to the default setting that allows for activation of the means for adjusting water temperature. For boiler controls that do not allow for control adjustment during active mode operation, terminate call for heat and adjust the inferential load controller in accordance with the I&O manual and then reinitiate call for heat. (2) If the means for adjusting water temperature uses outdoor temperature reset, the maximum outdoor temperature setting (if equipped) should be set to a temperature high enough that the boiler operates continuously during the duration of this test (i.e., if the conditions in paragraph (h)(1)(ii)(A) of this section equal room ambient temperature, then the maximum outdoor temperature should be set at a temperature greater than the ambient air temperature during the test). (ii) Establish low inferred load conditions at minimum boiler supply water temperature—(A) Establish low inferred load conditions. (1) Establish the inferred load conditions (simulated using a controlling parameter, such as outdoor temperature, thermostat patterns, or boiler cycling) so that the supply water temperature is maintained at the minimum supply water temperature prescribed by the boiler manufacturer's temperature reset control strategy found in the I&O manual. (2) The minimum supply water temperature of the default temperature reset curve is usually provided in the I&O manual. If there is no recommended minimum supply water temperature, set the minimum supply water temperature equal to 20 °F less than the high supply water temperature specified in paragraph (h)(1)(iii)(A) of this section. (B) Supply water temperature stabilization at low inferred load. (1) Maintain the call for heat until the boiler supply water temperature has stabilized. Temperature stabilization is deemed to be obtained when the boiler supply water temperature does not vary by more than ±3 °F over a period of five minutes. The duration of time required to stabilize the supply water, following the procedure in paragraph (h)(1)(ii)(A) of this section, is dependent on the reset strategy and may vary from model to model. (2) Record the boiler supply water temperature while the temperature is stabilized. (iii) Establish high inferred load conditions at maximum boiler supply water temperature—(A) Establish high inferred load conditions. Establish the inferred load conditions so that the supply water temperature is set to the maximum allowable supply water temperature as prescribed in the I&O manual, or if there is no recommendation, set to a temperature greater than 170 °F. (B) Supply water temperature stabilization at high inferred load. (1) Maintain the call for heat until the boiler supply water temperature has stabilized. Temperature stabilization is deemed to be obtained when the boiler supply water temperature does not vary by more than ±3 °F over a period of five minutes. The duration of time required to stabilize the supply water, following the procedure in paragraph (h)(1)(iii)(A) of this section, is dependent on the reset strategy and may vary from model to model. (2) Record the boiler supply water temperature while the temperature is stabilized. (3) Terminate the call for heat. (iv) [Reserved] (2) Test protocol for single-stage products employing burner delay. This test will be used in place of paragraph (h)(1) of this section for products manufacturers have certified to DOE under §429.18(b)(3) as employing a burner delay automatic means strategy. This test verifies whether the automatic means in single-stage boiler products establishes a burner delay upon a call for heat until the means has determined that the inferred heat load cannot be met by the residual heat of the water in the system. (i) Boiler setup—(A) Boiler installation. Boiler installation in the test room shall be in accordance with the setup and apparatus requirements by section 6.0 of appendix N to subpart B of 10 CFR part 430. (B) Activation of controls. Adjust the boiler controls in accordance with the I&O manual at the default setting that allows for activation of the means for adjusting water temperature. (C) Adjustment of water flow and temperature. The flow and temperature of inlet water to the boiler shall be capable of being adjusted manually. (ii) Boiler heat-up—(A) Boiler start-up. Power up the boiler and initiate a call for heat. (B) Adjustment of firing rate. Adjust the boiler's firing rate to within ±5% of its maximum rated input. (C) Establishing flow rate and temperature rise. Adjust the water flow through the boiler to achieve a ΔT of 20 °F (±2 °F) or greater with an inlet water temperature equal to 140 °F (±2 °F). (D) Terminate the call for heating. Terminate the call for heat, stop the flow of water through the boiler, and record the time at termination. (iii) Verify burner delay—(A) Reinitiate call for heat. Within three (3) minutes of termination (paragraph (h)(2)(ii)(D) of this section) and without adjusting the inlet water flow rate or temperature as specified in paragraph (h)(2)(ii)(C) of this section, reinitiate the call for heat and water flow and record the time. (B) Verify burner ignition. At 15-second intervals, record time and supply water temperature until the main burner ignites. (C) Terminate the call for heat. (iv) [Reserved] (i) Pumps—(1) General purpose pumps. (i) The volume rate of flow (flow rate) at BEP and nominal speed of rotation of each tested unit of the basic model will be measured pursuant to the test requirements of §431.464 of this chapter, where the value of volume rate of flow (flow rate) at BEP and nominal speed of rotation certified by the manufacturer will be treated as the expected BEP flow rate. The results of the measurement(s) will be compared to the value of volume rate of flow (flow rate) at BEP and nominal speed of rotation certified by the manufacturer. The certified volume rate of flow (flow rate) at BEP and nominal speed of rotation will be considered valid only if the measurement(s) (either the measured volume rate of flow (flow rate) at BEP and nominal speed of rotation for a single unit sample or the average of the measured flow rates for a multiple unit sample) is within five percent of the certified volume rate of flow (flow rate) at BEP and nominal speed of rotation. (A) If the representative value of volume rate of flow (flow rate) at BEP and nominal speed of rotation is found to be valid, the measured volume rate of flow (flow rate) at BEP and nominal speed of rotation will be used in subsequent calculations of constant load pump energy rating (PERCL) and constant load pump energy index (PEICL) or variable load pump energy rating (PERVL) and variable load pump energy index (PEIVL) for that basic model. (B) If the representative value of volume rate of flow (flow rate) at BEP and nominal speed of rotation is found to be invalid, the mean of all the measured volume rate of flow (flow rate) at BEP and nominal speed of rotation values determined from the tested unit(s) will serve as the new expected BEP flow rate and the unit(s) will be retested until such time as the measured rate of flow (flow rate) at BEP and nominal speed of rotation is within 5 percent of the expected BEP flow rate. (ii) DOE will test each pump unit according to the test method specified by the manufacturer in the certification report submitted pursuant to §429.59(b). (2) Dedicated-purpose pool pumps. (i) The rated hydraulic horsepower of each tested unit of the basic model of dedicated-purpose pool pump will be measured pursuant to the test requirements of §431.464(b) of this chapter and the result of the measurement(s) will be compared to the value of rated hydraulic horsepower certified by the manufacturer. The certified rated hydraulic horsepower will be considered valid only if the measurement(s) (either the measured rated hydraulic horsepower for a single unit sample or the average of the measured rated hydraulic horsepower values for a multiple unit sample) is within 5 percent of the certified rated hydraulic horsepower. (A) If the representative value of rated hydraulic horsepower is found to be valid, the value of rated hydraulic horsepower certified by the manufacturer will be used to determine the standard level for that basic model. (B) If the representative value of rated hydraulic horsepower is found to be invalid, the mean of all the measured rated hydraulic horsepower values determined from the tested unit(s) will be used to determine the standard level for that basic model. (ii) To verify the self-priming capability of non-self-priming pool filter pumps and of self-priming pool filter pumps that are not certified with NSF/ANSI 50-2015 (incorporated by reference, see §429.4) as self-priming, the vertical lift and true priming time of each tested unit of the basic model of self-priming or non-self-priming pool filter pump will be measured pursuant to the test requirements of §431.464(b) of this chapter. (A) For self-priming pool filter pumps that are not certified with NSF/ANSI 50-2015 as self-priming, at a vertical lift of 5.0 feet, the result of the true priming time measurement(s) will be compared to the value of true priming time certified by the manufacturer. The certified value of true priming time will be considered valid only if the measurement(s) (either the measured true priming time for a single unit sample or the average of true priming time values for a multiple unit sample) is within 5 percent of the certified value of true priming time. (1) If the representative value of true priming time is found to be valid, the value of true priming time certified by the manufacturer will be used to determine the appropriate equipment class and standard level for that basic model. (2) If the representative value of true priming time is found to be invalid, the mean of the values of true priming time determined from the tested unit(s) will be used to determine the appropriate equipment class and standard level for that basic model. (B) For non-self-priming pool filter pumps, at a vertical lift of 5.0 feet, the result of the true priming time measurement(s) (either the measured true priming time for a single unit sample or the average of true priming time values, for a multiple unit sample) will be compared to the value of true priming time referenced in the definition of non-self-priming pool filter pump at §431.462 (10.0 minutes). (1) If the measurement(s) of true priming time are greater than 95 percent of the value of true priming time referenced in the definition of non-self-priming pool filter pump at §431.462 with a vertical lift of 5.0 feet, the DPPP model will be considered a non-self-priming pool filter pump for the purposes of determining the appropriate equipment class and standard level for that basic model. (2) If the conditions specified in paragraph (i)(2)(ii)(B)(1) of this section are not satisfied, then the DPPP model will be considered a self-priming pool filter pump for the purposes of determining the appropriate equipment class and standard level for that basic model. (iii) To verify the maximum head of self-priming pool filter pump, non-self-priming pool filter pumps, and waterfall pumps, the maximum head of each tested unit of the basic model of self-priming pool filter pump, non-self-priming pool filter pump, or waterfall pump will be measured pursuant to the test requirements of §431.464(b) of this chapter and the result of the measurement(s) will be compared to the value of maximum head certified by the manufacturer. The certified value of maximum head will be considered valid only if the measurement(s) (either the measured maximum head for a single unit sample or the average of the maximum head values for a multiple unit sample) is within 5 percent of the certified values of maximum head. (A) If the representative value of maximum head is found to be valid, the value of maximum head certified by the manufacturer will be used to determine the appropriate equipment class and standard level for that basic model. (B) If the representative value of maximum head is found to be invalid, the measured value(s) of maximum head determined from the tested unit(s) will be used to determine the appropriate equipment class and standard level for that basic model. (iv) To verify that a DPPP model complies with the applicable freeze protection control design requirements, the initiation temperature, run-time, and speed of rotation of the default control configuration of each tested unit of the basic model of dedicated-purpose pool pump will be evaluated according to the procedure specified in paragraph (i)(2)(iv)(A) of this section: (A)(1) Set up and configure the dedicated-purpose pool pump under test according to the manufacturer instructions, including any necessary initial priming, in a test apparatus as described in appendix A of HI 40.6-2014-B (incorporated by reference, see §429.4), except that the ambient temperature registered by the freeze protection ambient temperature sensor will be able to be measured and controlled by, for example, exposing the freeze protection temperature sensor to a specific temperature by submerging the sensor in a water bath of known temperature, by adjusting the actual ambient air temperature of the test chamber and measuring the temperature at the freeze protection ambient temperature sensor location, or by other means that allows the ambient temperature registered by the freeze protection temperature sensor to be reliably simulated, varied, and measured. Do not adjust the default freeze protection control settings or enable the freeze protection control if it is shipped disabled. (2) Activate power to the pump with the flow rate set to zero (i.e., the pump is energized but not circulating water). Set the ambient temperature to 42.0 ± 0.5 °F and allow the temperature to stabilize, where stability is determined in accordance with section 40.6.3.2.2 of HI 40.6-2014-B. After 5 minutes, decrease the temperature measured by the freeze protection temperature sensor by 1.0 ± 0.5 °F and allow the temperature to stabilize. After each reduction in ambient temperature and subsequent stabilization, record the DPPP rotating speed, if any, and freeze protection ambient temperature reading, where the “freeze protection ambient temperature reading” is representative of the temperature measured by the freeze protection ambient temperature sensor, which may be recorded by a variety of means depending on how the temperature is being simulated and controlled. If no flow is initiated, record zero rpm or no flow. Continue decreasing the temperature measured by the freeze protection temperature sensor by 1.0 ± 0.5 °F after 5.0 minutes of stable operation at the previous temperature reading until the pump freeze protection initiates water circulation or until the ambient temperature of 38.0 ± 0.5 °F has been evaluated (i.e., the end of the 5.0 minute interval of 38.0 °F), whichever occurs first. (3) If and when the DPPP freeze protection controls initiate water circulation, increase the ambient temperature reading registered by the freeze protection temperature sensor to a temperature of 42.0 ± 0.5 °F and maintain that temperature for 60.0 minutes. Do not modify or interfere with the operation of the DPPP freeze protection operating cycle. After 60.0 minutes, record the freeze protection ambient temperature and rotating speed, if any, of the dedicated-purpose pool pump under test. (B) If the dedicated-purpose pool pump initiates water circulation at a temperature greater than 40.0 °F; if the dedicated-purpose pool pump was still circulating water after 60.0 minutes of operation at 42.0 ± 0.5 °F; or if rotating speed measured at any point during the DPPP freeze protection control test in paragraph (i)(2)(iii)(A) of this section was greater than one-half of the maximum rotating speed of the DPPP model certified by the manufacturer, that DPPP model is deemed to not comply with the design requirement for freeze protection controls. (C) If none of the conditions specified in paragraph (i)(2)(iv)(B) of this section are met, including if the DPPP freeze protection control does not initiate water circulation at all during the test, the dedicated-purpose pool pump under test is deemed compliant with the design requirement for freeze protection controls. (j) Refrigerated bottled or canned beverage vending machines—(1) Verification of refrigerated volume. The refrigerated volume (V) of each tested unit of the basic model will be measured pursuant to the test requirements of 10 CFR 431.296. The results of the measurement(s) will be compared to the representative value of refrigerated volume certified by the manufacturer. The certified refrigerated volume will be considered valid only if the measurement(s) (either the measured refrigerated volume for a single unit sample or the average of the measured refrigerated volumes for a multiple unit sample) is within five percent of the certified refrigerated volume. (i) If the representative value of refrigerated volume is found to be valid, the certified refrigerated volume will be used as the basis for calculation of maximum daily energy consumption for the basic model. (ii) If the representative value of refrigerated volume is found to be invalid, the average measured refrigerated volume determined from the tested unit(s) will serve as the basis for calculation of maximum daily energy consumption for the tested basic model. (2) Verification of surface area, transparent, and non-transparent areas. The percent transparent surface area on the front side of the basic model will be measured pursuant to these requirements for the purposes of determining whether a given basic model meets the definition of Class A or Combination A, as presented at 10 CFR 431.292. The transparent and non-transparent surface areas shall be determined on the front side of the beverage vending machine at the outermost surfaces of the beverage vending machine cabinet, from edge to edge, excluding any legs or other protrusions that extend beyond the dimensions of the primary cabinet. Determine the transparent and non-transparent areas on each side of a beverage vending machine as described in paragraphs (j)(2)(i) and (ii) of this section. For combination vending machines, disregard the surface area surrounding any refrigerated compartments that are not designed to be refrigerated (as demonstrated by the presence of temperature controls), whether or not it is transparent. Determine the percent transparent surface area on the front side of the beverage vending machine as a ratio of the measured transparent area on that side divided by the sum of the measured transparent and non-transparent areas, multiplying the result by 100. (i) Determination of transparent area. Determine the total surface area that is transparent as the sum of all surface areas on the front side of a beverage vending machine that meet the definition of transparent at 10 CFR 431.292. When determining whether or not a particular wall segment is transparent, transparency should be determined for the aggregate performance of all the materials between the refrigerated volume and the ambient environment; the composite performance of all those materials in a particular wall segment must meet the definition of transparent for that area be treated as transparent. (ii) Determination of non-transparent area. Determine the total surface area that is not transparent as the sum of all surface areas on the front side of a beverage vending machine that are not considered part of the transparent area, as determined in accordance with paragraph (j)(2)(i) of this section. (k) Central air conditioners and heat pumps—(1) Verification of cooling capacity. The cooling capacity of each tested unit of the individual model (for single-package systems) or individual combination (for split systems) will be measured pursuant to the test requirements of §430.23(m) of this chapter. The mean of the measurement(s) (either the measured cooling capacity for a single unit sample or the average of the measured cooling capacities for a multiple unit sample) will be used to determine the applicable standards for purposes of compliance. (2) Verification of CD value. (i) For central air conditioners and heat pumps other than models of outdoor units with no match, if manufacturers certify that they did not conduct the optional tests to determine the Cc and/or Ch value for an individual model (for single-package systems) or individual combination (for split systems), as applicable, the default Cc and/or Ch value will be used as the basis for calculation of SEER or HSPF for each unit tested. If manufacturers certify that they conducted the optional tests to determine the Cc and/or Ch value for an individual model (for single-package systems) or individual combination (for split systems), as applicable, the Cc and/or Ch value will be measured pursuant to the test requirements of §430.23(m) of this chapter for each unit tested and the result for each unit tested (either the tested value or the default value, as selected according to the criteria for the cyclic test in 10 CFR part 430, subpart B, appendix M, section 3.5e) used as the basis for calculation of SEER or HSPF for that unit. (ii) For models of outdoor units with no match, DOE will use the default Cc and/or Ch value pursuant to 10 CFR part 430. (l) Miscellaneous refrigeration products—(1) Verification of total refrigerated volume. For all miscellaneous refrigeration products, the total refrigerated volume of the basic model will be measured pursuant to the test requirements of part 430 of this chapter for each unit tested. The results of the measurement(s) will be averaged and compared to the value of total refrigerated volume certified by the manufacturer. The certified total refrigerated volume will be considered valid only if: (i) The measurement is within two percent, or 0.5 cubic feet (0.2 cubic feet for products with total refrigerated volume less than 7.75 cubic feet (220 liters)), whichever is greater, of the certified total refrigerated volume; or (ii) The measurement is greater than the certified total refrigerated volume. (A) If the certified total refrigerated volume is found to be valid, the certified adjusted total volume will be used as the basis for calculating the maximum allowed energy use for the tested basic model. (B) If the certified total refrigerated volume is found to be invalid, the average measured adjusted total volume, rounded to the nearest 0.1 cubic foot, will serve as the basis for calculating the maximum allowed energy use for the tested basic model. (2) Test for models with two compartments, each having its own user-operable temperature control. The test described in section 3.3 of the applicable test procedure in appendix A to subpart B part 430 of this chapter shall be used for all units of a tested basic model before DOE makes a determination of noncompliance with respect to the basic model. (m) Commercial packaged boilers—(1) Verification of fuel input rate. The fuel input rate of each tested unit will be measured pursuant to the test requirements of §431.86 of this chapter. The results of the measurement(s) will be compared to the value of rated input certified by the manufacturer. The certified rated input will be considered valid only if the measurement(s) (either the measured fuel input rate for a single unit sample or the average of the measured fuel input rates for a multiple unit sample) is within two percent of the certified rated input. (i) If the measured fuel input rate is within two-percent of the certified rated input, the certified rated input will serve as the basis for determination of the appropriate equipment class(es) and the mean measured fuel input rate will be used as the basis for calculation of combustion and/or thermal efficiency for the basic model. (ii) If the measured fuel input rate for a gas-fired commercial packaged boiler is not within two-percent of the certified rated input, DOE will first attempt to increase or decrease the gas manifold pressure within the range specified in manufacturer's installation and operation manual shipped with the commercial packaged boiler being tested (or, if not provided in the manual, in supplemental instructions provided by the manufacturer pursuant to §429.60(b)(4) of this chapter) to achieve the certified rated input (within two-percent). If the fuel input rate is still not within two-percent of the certified rated input, DOE will attempt to increase or decrease the gas inlet pressure within the range specified in manufacturer's installation and operation manual shipped with the commercial packaged boiler being tested (or, if not provided in the manual, in supplemental instructions provided by the manufacturer pursuant to §429.60(b)(4)) to achieve the certified rated input (within two-percent). If the fuel input rate is still not within two-percent of the certified rated input, DOE will attempt to modify the gas inlet orifice if the unit is equipped with one. If the fuel input rate still is not within two percent of the certified rated input, the mean measured fuel input rate (either for a single unit sample or the average of the measured fuel input rates for a multiple unit sample) will serve as the basis for determination of the appropriate equipment class(es) and calculation of combustion and/or thermal efficiency for the basic model. (iii) If the measured fuel input rate for an oil-fired commercial packaged boiler is not within two-percent of the certified rated input, the mean measured fuel input rate (either for a single unit sample or the average of the measured fuel input rates for a multiple unit sample) will serve as the basis for determination of the appropriate equipment class(es) and calculation of combustion and/or thermal efficiency for the basic model. (2) Models capable of producing both hot water and steam. For a model of commercial packaged boiler that is capable of producing both hot water and steam, DOE may measure the thermal or combustion efficiency as applicable (see §431.87 of this chapter) for steam and/or hot water modes. DOE will evaluate compliance based on the measured thermal or combustion efficiency in steam and hot water modes, independently. (n) Commercial water heating equipment other than residential-duty commercial water heaters—(1) Verification of fuel input rate. The fuel input rate of each tested unit of the basic model will be measured pursuant to the test requirements of §431.106 of this chapter. The measured fuel input rate (either the measured fuel input rate for a single unit sample or the average of the measured fuel input rates for a multiple unit sample) will be compared to the rated input certified by the manufacturer. The certified rated input will be considered valid only if the measured fuel input rate is within two percent of the certified rated input. (i) If the certified rated input is found to be valid, then the certified rated input will serve as the basis for determination of the appropriate equipment class and calculation of the standby loss standard (as applicable). (ii) If the measured fuel input rate for gas-fired commercial water heating equipment is not within two percent of the certified rated input, DOE will first attempt to increase or decrease the gas outlet pressure within 10 percent of the value specified on the nameplate of the model of commercial water heating equipment being tested to achieve the certified rated input (within 2 percent). If the fuel input rate is still not within two percent of the certified rated input, DOE will attempt to increase or decrease the gas supply pressure within the range specified on the nameplate of the model of commercial water heating equipment being tested. If the measured fuel input rate is still not within two percent of the certified rated input, DOE will attempt to modify the gas inlet orifice, if the unit is equipped with one. If the measured fuel input rate still is not within two percent of the certified rated input, the measured fuel input rate will serve as the basis for determination of the appropriate equipment class and calculation of the standby loss standard (as applicable). (iii) If the measured fuel input rate for oil-fired commercial water heating equipment is not within two percent of the certified rated input, the measured fuel input rate will serve as the basis for determination of the appropriate equipment class and calculation of the standby loss standard (as applicable). (2) [Reserved] (o) Uninterruptible power supplies. (1) Determine the UPS architecture by performing the tests specified in the definitions of VI, VFD, and VFI in sections 2.28.1 through 2.28.3 of appendix Y to subpart B of 10 CFR part 430. (2) [Reserved] (p) Compressors—(1) Verification of full-load operating pressure. (i) The maximum full-flow operating pressure of each tested unit of the basic model will be measured pursuant to the test requirements of appendix A to subpart T of part 431 of this chapter, where 90 percent of the value of full-load operating pressure certified by the manufacturer will be the starting point of the test method prior to increasing discharge pressure. The measured maximum full-flow operating pressure (either the single measured value for a single unit sample or the mean of the measured maximum full-flow operating pressures for a multiple unit sample) will be compared to the certified rating for full-load operating pressure to determine if the certified rating is valid or not. The certified rating for full-load operating pressure will be considered valid only if the certified rating for full-load operating pressure is less than or equal to the measured maximum full-flow operating pressure and greater than or equal to the lesser of— (A) 90 percent of the measured maximum full-flow operating pressure; or (B) 10 psig less than the measured maximum full-flow operating pressure. (ii) If the certified full-load operating pressure is found to be valid, then the certified value will be used as the full-load operating pressure and will be the basis for determination of full-load actual volume flow rate, pressure ratio at full-load operating pressure, specific power, and package isentropic efficiency. (iii) If the certified full-load operating pressure is found to be invalid, then the measured maximum full-flow operating pressure will be used as the full-load operating pressure and will be the basis for determination of full-load actual volume flow rate, pressure ratio at full-load operating pressure, specific power, and package isentropic efficiency. (2) Verification of full-load actual volume flow rate. The measured full-load actual volume flow rate will be measured, pursuant to the test requirements of appendix A to subpart T of part 431 of this chapter, at the full-load operating pressure determined in paragraph (p)(1) of this section. The certified full-load actual volume flow rate will be considered valid only if the measurement(s) (either the measured full-load actual volume flow rate for a single unit sample or the mean of the measured values for a multiple unit sample) are within the percentage of the certified full-load actual volume flow rate specified in Table 1 of this section: Table 1 of §429.134—Allowable Percentage Deviation From the Certified Full-Load Actual Volume Flow Rate
(i) If the certified value of full-load actual volume flow rate is found to be valid, the full-load actual volume flow rate certified by the manufacturer will be used as the basis for determination of the applicable standard. (ii) If the certified value of full-load actual volume flow rate is found to be invalid, the entire sample (one or multiple units) will be considered as failing the enforcement test. (3) Ancillary equipment. Prior to testing each compressor, DOE will install any required ancillary equipment specified by the manufacturer in the certification report submitted pursuant to §429.63(b). (q) Walk-in coolers and walk-in freezers. (1) If DOE determines that a basic model of a panel, door, or refrigeration system for walk-in coolers or walk-in freezers fails to meet an applicable energy conservation standard, then the manufacturer of that basic model is responsible for the noncompliance. If DOE determines that a complete walk-in cooler or walk-in freezer or component thereof fails to meet an applicable energy conservation standard, then the manufacturer of that walk-in cooler or walk-in freezer is responsible for the noncompliance with the applicable standard, except that the manufacturer of a complete walk-in cooler or walk-in freezer is not responsible for the use of components that were certified and labeled (in accordance with DOE labeling requirements) as compliant by another party and later found to be noncompliant with the applicable standard(s). (2) Verification of refrigeration system net capacity. The net capacity of the refrigeration system basic model will be measured pursuant to the test requirements of 10 CFR part 431, subpart R, appendix C for each unit tested. The results of the measurement(s) will be averaged and compared to the value of net capacity certified by the manufacturer. The certified net capacity will be considered valid only if the average measured net capacity is within plus or minus five percent of the certified net capacity. (i) If the certified net capacity is found to be valid, the certified net capacity will be used as the basis for calculating the AWEF of the basic model. (ii) If the certified net capacity is found to be invalid, the average measured net capacity will serve as the basis for calculating the annual energy consumption for the basic model. (3) Verification of door surface area. The surface area of a display door or non-display door basic model will be measured pursuant to the requirements of 10 CFR part 431, subpart R, appendix A for each unit tested. The results of the measurement(s) will be averaged and compared to the value of the surface area certified by the manufacturer. The certified surface area will be considered valid only if the average measured surface area is within plus or minus three percent of the certified surface area. (i) If the certified surface area is found to be valid, the certified surface area will be used as the basis for calculating the maximum energy consumption (kWh/day) of the basic model. (ii) If the certified surface area is found to be invalid, the average measured surface area will serve as the basis for calculating the maximum energy consumption (kWh/day) of the basic model. (4) For each basic model of walk-in cooler and walk-in freezer door, DOE will calculate the door's energy consumption using the power listed on the nameplate of each electricity consuming device shipped with the door. If an electricity consuming device shipped with a walk-in door does not have a nameplate or such nameplate does not list the device's power, then DOE will use the device's “rated power” included in the door's certification report.

[81 FR 45403, July 14, 2016] ## §429.148 Routine violator.(a) DOE will consider, inter alia, the following factors in determining if a person is a routine violator: Number of violations in current and past cases, length of time over which violations occurred, ratio of compliant to noncompliant installations or sales, percentage of employees committing violations, evidence of intent, evidence of training or education provided, and subsequent remedial actions. (b) In the event that DOE determines a person to be a routine violator, DOE will issue a Notice of Finding of Routine Violation. (c) In making a finding of Routine Violation, DOE will consider whether the Routine Violation was limited to a specific location. If DOE finds that the routine violation was so limited, DOE may, in its discretion, in the Notice of Finding of Routine Violation limit the prohibition on manufacturer and/or private labeler sales to a particular contractor or distribution location. [81 FR 45403, July 14, 2016] ## §429.150 Appealing a finding of routine violation.(a) Any person found to be a routine violator may, within 30 calendar days after the date of Notice of Finding of Routine Violation, request an administrative appeal to the Office of Hearings and Appeals. (b) The appeal must present information rebutting the finding of violation(s). (c) The Office of Hearings and Appeals will issue a decision on the appeal within 45 days of receipt of the appeal. (d) A routine violator must file a Notice of Intent to Appeal with the Office of Hearings and Appeals within three business days of the date of the Notice of Finding of Routine Violation, serving a copy on the Office of the Assistant General Counsel for Enforcement to retain the ability to buy central air conditioners during the pendency of the appeal. [81 FR 45403, July 14, 2016] ## §429.152 Removal of finding of “routine violator”.(a) A routine violator may be removed from DOE's list of routine violators through completion of remediation in accordance with the requirements in §429.154. (b) A routine violator that wants to remediate must contact the Office of the Assistant General Counsel for Enforcement via the point of contact listed in the Notice of Finding of Routine Violation and identify the distributor(s), manufacturer(s), or private labeler(s) from whom it wishes to buy compliant replacement product. (c) DOE will contact the distributor(s), manufacturer(s), or private labeler(s) and authorize sale of central air conditioner units to the routine violator for purposes of remediation within 3 business days of receipt of the request for remediation. DOE will provide the manufacturer(s), distributor(s), and/or private labeler(s) with an official letter authorizing the sale of units for purposes of remediation. (d) DOE will contact routine violators that requested units for remediation within 30 days of sending the official letter to the manufacturer(s), distributor(s), and/or private labeler(s) to determine the status of the remediation. (e) If remediation is successfully completed, DOE will issue a Notice indicating a person is no longer considered to be a routine violator. The Notice will be issued no more than 30 days after DOE has received documentation demonstrating that remediation is complete. [81 FR 45403, July 14, 2016] ## §429.154 Remediation.(a) Any party found to be in violation of the regional standards may remediate by replacing the noncompliant unit at cost to the violator; the end user cannot be charged for any costs of remediation. (1) If a violator is unable to replace all noncompliant installations, then the Department may, in its discretion, consider the remediation complete if the violator satisfactorily demonstrates to the Department that it attempted to replace all noncompliant installations. (2) The Department will scrutinize any “failed” attempts at replacement to ensure that there was indeed a good faith effort to complete remediation of the noncompliant unit. (b) The violator must provide to DOE the serial number of any outdoor unit and/or indoor unit installed not in compliance with the applicable regional standard as well as the serial number(s) of the replacement unit(s) to be checked by the Department against warranty and other replacement claims. (c) If the remediation is approved by the Department, then DOE will issue a Notice of Remediation and the violation will not count towards a finding of “routine violator”. [81 FR 45403, July 14, 2016] ## §429.156 Manufacturer and private labeler liability.(a) In accordance with §429.102, paragraphs (a)(10) and (c), manufacturers and private labelers are prohibited from selling central air conditioners and heat pumps to a routine violator. (1) To avoid financial penalties, manufacturers and/or private labelers must cease sales to a routine violator within 3 business days from the date of issuance of a Notice of Finding of Routine Violation. (2) If a Routine Violator files a Notice of Intent to Appeal pursuant to §429.150, then a manufacturer and/or private labeler may assume the risk of selling central air conditioners to the Routine Violator during the pendency of the appeal. (3) If the appeal of the Finding of Routine Violator is denied, then the manufacturer and/or private labeler may be fined in accordance with §429.120, for sale of any units to a routine violator during the pendency of the appeal that do not meet the applicable regional standard. (b) If a manufacturer and/or private labeler has knowledge of routine violation, then the manufacturer can be held liable for all sales that occurred after the date the manufacturer had knowledge of the routine violation. However, if the manufacturer and/or private labeler reports its suspicion of a routine violation to DOE within 15 days of receipt of such knowledge, then it will not be liable for product sold to the suspected routine violator prior to reporting the routine violation to DOE. [81 FR 45403, July 14, 2016] ## §429.158 Product determined noncompliant with regional standards.(a) If DOE determines a model of outdoor unit fails to meet the applicable regional standard(s) when tested in a combination certified by the same manufacturer, then the outdoor unit basic model will be deemed noncompliant with the regional standard(s). In accordance with §429.102(c), the outdoor unit manufacturer and/or private labeler is liable for distribution of noncompliant units in commerce. (b) If DOE determines a combination fails to meet the applicable regional standard(s) when tested in a combination certified by a manufacturer other than the outdoor unit manufacturer (e.g., ICM), then that combination is deemed noncompliant with the regional standard(s). In accordance with §429.102(c), the certifying manufacturer is liable for distribution of noncompliant units in commerce. (c) All such units manufactured and distributed in commerce are presumed to have been installed in a region where they would not comply with the applicable energy conservation standard; however, a manufacturer and/or private labeler may demonstrate through installer records that individual units were installed in a region where the unit is compliant with the applicable standards. [81 FR 45404, July 14, 2016] ## Appendix A to Subpart C of Part 429—Sampling Plan for Enforcement Testing of Covered Consumer Products and Certain High-Volume Commercial Equipment(a) The first sample size (n1) for enforcement testing must be four or more units, except as provided by §429.57(e)(1)(i). (b) Compute the mean of the measured energy performance (x1) for all tests as follows:
where xi is the measured energy or water efficiency or consumption from test i, and n1 is the total number of tests. (c) Compute the standard deviation (s1) of the measured energy performance from the n1 tests as follows: (d) Compute the standard error (sx1) of the measured energy performance from the n1 tests as follows: (e)(1) Compute the upper control limit (UCL1) and lower control limit (LCL1) for the mean of the first sample using the applicable DOE energy efficiency standard (EES) as the desired mean and a probability level of 95 percent (two-tailed test) as follows: LCL1 EES — tsX1 X
where t is the statistic based on a 95 percent two-tailed probability level with degrees of freedom (n1−1). (2) For an energy efficiency or water efficiency standard, compare the mean of the first sample (x1) with the upper and lower control limits (UCL1 and LCL1) to determine one of the following: (i) If the mean of the first sample is below the lower control limit, then the basic model is in noncompliance and testing is at an end. (Do not go on to any of the steps below.) (ii) If the mean of the first sample is equal to or greater than the upper control limit, then the basic model is in compliance and testing is at an end. (Do not go on to any of the steps below.) (iii) If the sample mean is equal to or greater than the lower control limit but less than the upper control limit, then no determination of compliance or noncompliance can be made and a second sample size is determined by Step (e)(3). (3) For an energy efficiency or water efficiency standard, determine the second sample size (n2) as follows:
where s1 and t have the values used in equations 2 and 4, respectively. The term “0.05 EES” is the difference between the applicable energy efficiency or water efficiency standard and 95 percent of the standard, where 95 percent of the standard is taken as the lower control limit. This procedure yields a sufficient combined sample size (n1 + n2) to give an estimated 97.5 percent probability of obtaining a determination of compliance when the true mean efficiency is equal to the applicable standard. Given the solution value of n2, determine one of the following: (i) If the value of n2 is less than or equal to zero and if the mean energy or water efficiency of the first sample (x1) is either equal to or greater than the lower control limit (LCL1) or equal to or greater than 95 percent of the applicable energy efficiency or water efficiency standard (EES), whichever is greater, i.e., if n2≤0 and x1≥max (LCL1, 0.95 EES), the basic model is in compliance and testing is at an end. (ii) If the value of n2 is less than or equal to zero and the mean energy efficiency of the first sample (x1) is less than the lower control limit (LCL1) or less than 95 percent of the applicable energy or water efficiency standard (EES), whichever is greater, i.e., if n2≤0 and x1≤max (LCL1, 0.95 EES), the basic model is not in compliance and testing is at an end. (iii) If the value of n2 is greater than zero, then, the value of the second sample size is determined to be the smallest integer equal to or greater than the solution value of n2 for equation (6). If the value of n2 so calculated is greater than 21− n1, set n2 equal to 21− n1. (4) Compute the combined mean (x2) of the measured energy or water efficiency of the n1 and n2 units of the combined first and second samples as follows: (5) Compute the standard error (Sx2) of the measured energy or water performance of the n1 and n2 units in the combined first and second samples as follows:
Note: s1 is the value obtained in Step (c). (6) For an energy efficiency standard (EES), compute the lower control limit (LCL2) for the mean of the combined first and second samples using the DOE EES as the desired mean and a one-tailed probability level of 97.5 percent (equivalent to the two-tailed probability level of 95 percent used in Step (e)(1)) as follows:
where the t-statistic has the value obtained in Step (e)(1) and sx2 is the value obtained in Step (e)(5). (7) For an energy efficiency standard (EES), compare the combined sample mean (x2) to the lower control limit (LCL2) to determine one of the following: (i) If the mean of the combined sample (x2) is less than the lower control limit (LCL2) or 95 percent of the applicable energy efficiency standard (EES), whichever is greater, i.e., if x2<max (LCL2, 0.95 EES), the basic model is not compliant and testing is at an end. (iii) If the mean of the combined sample (x2) is equal to or greater than the lower control limit (LCL2) or 95 percent of the applicable energy efficiency standard (EES), whichever is greater, i.e., if x2≥max (LCL2, 0.95 EES), the basic model is in compliance and testing is at an end. (f)(1) Compute the upper control limit (UCL1) and lower control limit (LCL1) for the mean of the first sample using the applicable DOE energy consumption standard (ECS) as the desired mean and a probability level of 95 percent (two-tailed test) as follows:
where t is the statistic based on a 95 percent two-tailed probability level with degrees of freedom (n1 − 1). (2) For an energy or water consumption standard, compare the mean of the first sample (x1) with the upper and lower control limits (UCL1 and LCL1) to determine one of the following: (i) If the mean of the first sample is above the upper control limit, then the basic model is in noncompliance and testing is at an end. (Do not go on to any of the steps below.) (ii) If the mean of the first sample is equal to or less than the lower control limit, then the basic model is in compliance and testing is at an end. (Do not go on to any of the steps below.) (iii) If the sample mean is equal to or less than the upper control limit but greater than the lower control limit, then no determination of compliance or noncompliance can be made and a second sample size is determined by Step (f)(3). (3) For an Energy or Water Consumption Standard, determine the second sample size (n2) as follows:
where s1and t have the values used in equations (2) and (10), respectively. The term “0.05 ECS” is the difference between the applicable energy or water consumption standard and 105 percent of the standard, where 105 percent of the standard is taken as the upper control limit. This procedure yields a sufficient combined sample size (n1 + n2) to give an estimated 97.5 percent probability of obtaining a determination of compliance when the true mean consumption is equal to the applicable standard. Given the solution value of n2, determine one of the following: (i) If the value of n2 is less than or equal to zero and if the mean energy or water consumption of the first sample (x1) is either equal to or less than the upper control limit (UCL1) or equal to or less than 105 percent of the applicable energy or water consumption standard (ECS), whichever is less, i.e., if n2 ≤0 and x1 ≤min (UCL1, 1.05 ECS), the basic model is in compliance and testing is at an end. (ii) If the value of n2 is less than or equal to zero and the mean energy or water consumption of the first sample (x1) is greater than the upper control limit (UCL1) or more than 105 percent of the applicable energy or water consumption standard (ECS), whichever is less, i.e., if n2 ≤0 and x1 >min (UCL1, 1.05 EPS), the basic model is not compliant and testing is at an end. (iii) If the value of n2 is greater than zero, then the value of the second sample size is determined to be the smallest integer equal to or greater than the solution value of n2 for equation (11). If the value of n2 so calculated is greater than 21−n1, set n2 equal to 21−n1. (4) Compute the combined mean (x2) of the measured energy or water consumption of the n1 and n2 units of the combined first and second samples as follows: (5) Compute the standard error (Sx2) of the measured energy or water consumption of the n1 and n2 units in the combined first and second samples as follows:
Note: s1 is the value obtained in Step (c). (6) For an energy or water consumption standard (ECS), compute the upper control limit (UCL2) for the mean of the combined first and second samples using the DOE ECS as the desired mean and a one-tailed probability level of 97.5 percent (equivalent to the two-tailed probability level of 95 percent used in Step (f)(1)) as follows:
where the t-statistic has the value obtained in (f)(1). (7) For an energy or water consumption standard (ECS), compare the combined sample mean (x2) to the upper control limit (UCL2) to determine one of the following: (i) If the mean of the combined sample (x2) is greater than the upper control limit (UCL2) or 105 percent of the ECS whichever is less, i.e., if x2 >min (UCL2, 1.05 ECS), the basic model is not compliant and testing is at an end. (ii) If the mean of the combined sample (x2) is equal to or less than the upper control limit (UCL2) or 105 percent of the applicable energy or water performance standard (ECS), whichever is less, i.e., if x 2≤min (UCL2, 1.05 ECS), the basic model is in compliance and testing is at an end. ## Appendix B to Subpart C of Part 429—Sampling Plan for Enforcement Testing of Covered Equipment and Certain Low-Volume Covered ProductsThe Department will determine compliance as follows: (a) The first sample size (n1) must be four or more units, except as provided by §429.57(e)(1)(ii).

Where EES is the energy efficiency standard and t is a statistic based on a 97.5 percent, one-sided confidence limit and a sample size of n1. (2) For an energy consumption standard (ECS), determine the appropriate upper control limit (UCL1) according to: And use whichever is less, where ECS is the energy consumption standard and t is a statistic based on a 97.5 percent, one-sided confidence limit and a sample size of n1. (f)(1) Compare the sample mean to the control limit. (i) The basic model is in compliance and testing is at an end if: (A) For an energy or water efficiency standard, the sample mean is equal to or greater than the lower control limit, or (B) For an energy or water consumption standard, the sample mean is equal to or less than the upper control limit. ## Appendix C to Subpart C of Part 429—Sampling Plan for Enforcement Testing of Distribution Transformers(a) When testing distribution transformers, the number of units in the sample (m1) shall be in accordance with §429.47(a) and DOE shall perform the following number of tests: (1) If DOE tests four or more units, it will test each unit once; (2) If DOE tests two or three units, it will test each unit twice; or (3) If DOE tests one unit, it will test that unit four times.
