For purposes of carrying out parts 429, 430, and 431, the General Counsel (or delegee), may sign and issue subpoenas for the attendance and testimony of witnesses and the production of relevant books, records, papers, and other documents, and administer oaths. Witnesses summoned under the provisions of this section shall be paid the same fees and mileage as are paid to witnesses in the courts of the United States. In case of contumacy by, or refusal to obey a subpoena served, upon any persons subject to parts 429, 430, or 431, the General Counsel (or delegee) may seek an order from the District Court of the United States for any District in which such person is found or resides or transacts business requiring such person to appear and give testimony, or to appear and produce documents. Failure to obey such order is punishable by such court as contempt thereof.
This subpart sets forth the procedures for manufacturers to certify that their covered products and covered equipment comply with the applicable energy conservation standards.
(a) When testing of covered products or covered equipment is required to comply with section 323(c) of the Act, or to comply with rules prescribed under section 324, 325, or 342, 344, 345 or 346 of the Act, a sample comprised of production units (or units representative of production units) of the basic model being tested must be selected at random and tested, and must meet the criteria found in §§ 429.14 through 429.62 of this subpart. Components of similar design may be substituted without additional testing if the substitution does not affect energy or water consumption. Any represented values of measures of energy efficiency, water efficiency, energy consumption, or water consumption for all individual models represented by a given basic model must be the same, except for central air conditioners and central air conditioning heat pumps, as specified in § 429.16 of this subpart.
(b) The minimum number of units tested shall be no less than two, except where:
(1) A different minimum limit is specified in §§ 429.14 through 429.65 of this subpart; or
(2) Only one unit of the basic model is produced, in which case, that unit must be tested and the test results must demonstrate that the basic model performs at or better than the applicable standard(s). If one or more units of the basic model are manufactured subsequently, compliance with the default sampling and representations provisions is required.
[76 FR 12451, Mar. 7, 2011, as amended at 81 FR 4144, Jan. 25, 2016; 81 FR 89303, Dec. 9, 2016; 82 FR 1468, Jan. 5, 2017]
(a) Certification. Each manufacturer, before distributing in commerce any basic model of a covered product or covered equipment subject to an applicable energy conservation standard set forth in parts 430 or 431, and annually thereafter on or before the dates provided in paragraph (d) of this section, shall submit a certification report to DOE certifying that each basic model meets the applicable energy conservation standard(s). The certification report(s) must be submitted to DOE in accordance with the submission procedures of paragraph (h) of this section.
(b) Certification report. A certification report shall include a compliance statement (see paragraph (c) of this section), and for each basic model, the information listed in this paragraph (b).

(e) New model filing.
(1) In addition to the annual filing schedule in paragraph (d) of this section, any new basic models must be certified pursuant to paragraph (a) of this section before distribution in commerce. A modification to a model that increases the model's energy or water consumption or decreases its efficiency resulting in re-rating must be certified as a new basic model pursuant to paragraph (a) of this section.
(2) For general service fluorescent lamps or incandescent reflector lamps: Prior to or concurrent with the distribution of a new basic model each manufacturer shall submit an initial certification report listing the basic model number, lamp wattage, and date of first manufacture (i.e., production date) for that basic model. The certification report must also state how the manufacturer determined that the lamp meets or exceeds the energy conservation standards, including a description of any testing or analysis the manufacturer performed. Manufacturers of general service fluorescent lamps and incandescent reflector lamps shall submit the certification report required by paragraph (b) of this section within one year after the first date of new model manufacture.
(3) For distribution transformers, the manufacturer shall submit all information required in paragraphs (b) and (c) of this section for the new basic model, unless the manufacturer has previously submitted to the Department a certification report for a basic model of distribution transformer that is in the same kVA grouping as the new basic model.
(f) Discontinued model filing. When production of a basic model has ceased and it is no longer being sold or offered for sale by the manufacturer or private labeler, the manufacturer must report this discontinued status to DOE as part of the next annual certification report following such cessation. For each basic model, the report must include the information specified in paragraphs (b)(1) through (7) of this section, except that for integrated light-emitting diode lamps and for compact fluorescent lamps, the manufacturer must submit a full certification report, including all of the information required by paragraph (b) of this section and the product-specific information required by § 429.56(b)(2) or § 429.35(b)(2), respectively.
(g) Third party submitters. A manufacturer may elect to use a third party to submit the certification report to DOE (for example, a trade association, independent test lab, or other authorized representative, including a private labeler acting as a third party submitter on behalf of a manufacturer); however, the manufacturer is responsible for submission of the certification report to DOE. DOE may refuse to accept certification reports from third party submitters who have failed to submit reports in accordance with the rules of this part. The third party submitter must complete the compliance statement as part of the certification report. Each manufacturer using a third party submitter must have an authorization form on file with DOE. The authorization form includes a compliance statement, specifies the third party authorized to submit certification reports on the manufacturer's behalf and provides the contact information and signature of a company official.
(h) Method of submission. Reports required by this section must be submitted to DOE electronically at http://www.regulations.doe.gov/ccms (CCMS). A manufacturer or third party submitter can find product-specific templates for each covered product or covered equipment with certification requirements online at https://www.regulations.doe.gov/ccms/templates.html. Manufacturers and third party submitters must submit a registration form, signed by an officer of the company, in order to obtain access to CCMS.

(1) Required represented values. Determine the represented values (including SEER, EER, HSPF, SEER2, EER2, HSPF2, P_{W,OFF}, cooling capacity, and heating capacity, as applicable) for the individual models/combinations (or “tested combinations”) specified in the following table.
Category | Equipment subcategory | Required represented values |
---|---|---|
Single-Package unit | Single-Package AC (including Space-Constrained) | Every individual model distributed in commerce. |
Single-Package HP (including Space-Constrained) | ||
Outdoor Unit and Indoor Unit (Distributed in Commerce by OUM) | Single-Split-System AC with Single-Stage or Two-Stage Compressor (including Space-Constrained and Small-Duct, High Velocity Systems (SDHV)) | Every individual combination distributed in commerce must be rated as a coil-only combination. For each model of outdoor unit, this must include at least one coil-only value that is representative of the least efficient combination distributed in commerce with that particular model of outdoor unit. Additional blower-coil representations are allowed for any applicable individual combinations, if distributed in commerce. |
Single-Split-System AC with Other Than Single-Stage or Two-Stage Compressor (including Space-Constrained and SDHV) | Every individual combination distributed in commerce, including all coil-only and blower coil combinations. | |

Multi-Split, Multi-Circuit, or Multi-Head Mini-Split Split System - non-SDHV (including Space-Constrained) | For each model of outdoor unit, at a minimum, a non-ducted “tested combination.” For any model of outdoor unit also sold with models of ducted indoor units, a ducted “tested combination.” When determining represented values on or after January 1, 2023, the ducted “tested combination” must comprise the highest static variety of ducted indoor unit distributed in commerce (i.e., conventional, mid-static, or low-static). Additional representations are allowed, as described in paragraph (c)(3)(i) of this section. | |
Multi-Split, Multi-Circuit, or Multi-Head Mini-Split Split System - SDHV | For each model of outdoor unit, an SDHV “tested combination.” Additional representations are allowed, as described in paragraph (c)(3)(ii) of this section. | |
Indoor Unit Only Distributed in Commerce by ICM) | Single-Split-System Air Conditioner (including Space-Constrained and SDHV) | Every individual combination distributed in commerce. |
Single-Split-System Heat Pump (including Space-Constrained and SDHV) | ||
Multi-Split, Multi-Circuit, or Multi-Head Mini-Split Split System - SDHV | For a model of indoor unit within each basic model, an SDHV “tested combination.” Additional representations are allowed, as described in section (c)(3)(ii) of this section. | |
Outdoor Unit with no Match | Every model of outdoor unit distributed in commerce (tested with a model of coil-only indoor unit as specified in paragraph (b)(2)(i) of this section). |
(2) P_{W,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, P_{W,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, P_{W,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.

The least efficient model of outdoor unit is the model of outdoor unit in the lowest SEER combination (when testing under appendix M to subpart B of part 430) or SEER2 combination (when testing under appendix M1 to subpart B of part 430) as certified by the OUM. If there are multiple models of outdoor unit with the same lowest SEER represented value (when testing under appendix M to subpart B of part 430) or SEER2 represented value (when testing under appendix M1 to subpart B of part 430), the ICM may select one for testing purposes. | |
Outdoor Unit with No Match | The model of outdoor unit | A model of coil-only indoor unit meeting the requirements of section 2.2e of appendix M or M1 to subpart B of part 430. |
(ii) Each individual model/combination (or “tested combination”) identified in paragraph (b)(2)(i) of this section is not required to be tested for P_{W,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 P_{W,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.

^{1} The minimum number of tests indicated above must be comprised of a transparent model, a solid model, a vertical model, a semi-vertical model, a horizontal model, and a service-over-the counter model, as applicable based on the equipment offering. However, manufacturers do not need to include all types of these models if it will increase the minimum number of tests that need to be conducted.
(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.

(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).

[76 FR 12451, Mar. 7, 2011, as amended at 81 FR 4145, Jan. 25, 2016; 81 FR 45402, July 14, 2016]
DOE may, at any time, test a basic model to assess whether the basic model is in compliance with the applicable energy conservation standard(s).
(a) DOE may initiate an investigation that a basic model may not be compliant with an applicable conservation standard, certification requirement or other regulation at any time.
(b) DOE may, at any time, request any information relevant to determining compliance with any requirement under parts 429, 430 and 431, including the data underlying certification of a basic model. Such data may be used by DOE to make a determination of compliance or noncompliance with an applicable standard.
(a) General provisions.
(1) If DOE has reason to believe that a basic model is not in compliance it may test for enforcement.
(2) DOE will select and test units pursuant to paragraphs (c) and (e) of this section.
(3) Testing will be conducted at a laboratory accredited to the International Organization for Standardization (ISO)/International Electrotechnical Commission (IEC), “General requirements for the competence of testing and calibration laboratories,” ISO/IEC 17025:2005(E) (incorporated by reference; see § 429.4). If testing cannot be completed at an independent laboratory, DOE, at its discretion, may allow enforcement testing at a manufacturer's laboratory, so long as the lab is accredited to ISO/IEC 17025:2005(E) and DOE representatives witness the testing. 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 (n_{1}) 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) In the event that DOE determines a basic model is noncompliant with an applicable energy conservation standard, or if a manufacturer or private labeler determines a basic model to be in noncompliance, DOE may issue a notice of noncompliance determination to the manufacturer or private labeler. This notice of noncompliance determination will notify the manufacturer or private labeler of its obligation to:
(1) Immediately cease distribution in commerce of the basic model;
(2) Give immediate written notification of the determination of noncompliance to all persons to whom the manufacturer has distributed units of the basic model manufactured since the date of the last determination of compliance; and
(3) Provide DOE, within 30 calendar days of the request, records, reports and other documentation pertaining to the acquisition, ordering, storage, shipment, or sale of a basic model determined to be in noncompliance.
(b) In the event that DOE determines a manufacturer has failed to comply with an applicable certification requirement with respect to a particular basic model, DOE may issue a notice of noncompliance determination to the manufacturer or private labeler. This notice of noncompliance determination will notify the manufacturer or private labeler of its obligation to:
(1) Immediately cease distribution in commerce of the basic model;
(2) Immediately comply with the applicable certification requirement; and/or
(3) Provide DOE within 30 days of the request, records, reports and other documentation pertaining to the acquisition, ordering, storage, shipment, or sale of the basic model.
(c) If a manufacturer or private labeler fails to comply with the required actions in the notice of noncompliance determination as set forth in paragraphs (a) or (b) of this section, the General Counsel (or delegee) may seek, among other remedies, injunctive action and civil penalties, where appropriate.
(d) The manufacturer may modify a basic model determined to be noncompliant with an applicable energy conservation standard in such manner as to make it comply with the applicable standard. Such modified basic model shall then be treated as a new basic model and must be certified in accordance with the provisions of this part; except that in addition to satisfying all requirements of this part, any models within the basic model must be assigned new model numbers and the manufacturer shall also maintain, and provide upon request to DOE, records that demonstrate that modifications have been made to all units of the new basic model prior to distribution in commerce.
Pursuant to § 429.102(b)(2), if DOE determines that independent, third-party testing is necessary to ensure a manufacturer's compliance with the rules of this part, part 430, or part 431, a manufacturer must base its certification of a basic model under subpart B of this part on independent, third-party laboratory testing.
If DOE has reason to seek an injunction under the Act:
(a) DOE will notify the manufacturer, private labeler or any other person as required, of the prohibited act at issue and DOE's intent to seek a judicial order enjoining the prohibited act unless the manufacturer, private labeler or other person, delivers to DOE within 15 calendar days a corrective action and compliance plan, satisfactory to DOE, of the steps it will take to ensure that the prohibited act ceases. DOE will monitor the implementation of such plan.
(b) If the manufacturer, private labeler or any other person as required, fails to cease engaging in the prohibited act or fails to provide a satisfactory corrective action and compliance plan, DOE may seek an injunction.
Any person who knowingly violates any provision of § 429.102(a) may be subject to assessment of a civil penalty of no more than $474 for each violation. As to § 429.102(a)(1) with respect to failure to certify, and as to § 429.102(a)(2), (5) through (9), each unit of a covered product or covered equipment distributed in violation of such paragraph shall constitute a separate violation. For violations of § 429.102(a)(1), (3), and (4), each day of noncompliance shall constitute a separate violation for each basic model at issue.

(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.

(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 (PER_{CL}) and constant load pump energy index (PEI_{CL}) or variable load pump energy rating (PER_{VL}) and variable load pump energy index (PEI_{VL}) 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).

(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.

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.

(2) Verification of C_{D} 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.

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).

(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
Manufacturer certified full-load actual volume flow rate (m^{3}/s) × 10^{−3} |
Allowable percent of the certified full-load actual volume flow rate (%) |
---|---|
0 < and ≤ 8.3 | ±7 |
8.3 < and ≤ 25 | ±6 |
25 < and ≤ 250 | ±5 |
> 250 | ±4 |
(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.
(r) Portable air conditioners. Verification of seasonally adjusted cooling capacity. The seasonally adjusted cooling capacity 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 seasonally adjusted cooling capacity certified by the manufacturer. The certified seasonally adjusted cooling capacity will be considered valid only if the average measured seasonally adjusted cooling capacity is within five percent of the certified seasonally adjusted cooling capacity.
(1) If the certified seasonally adjusted cooling capacity is found to be valid, the certified value will be used as the basis for determining the minimum allowed combined energy efficiency ratio for the basic model.
(2) If the certified seasonally adjusted cooling capacity is found to be invalid, the average measured seasonally adjusted cooling capacity will be used to determine the minimum allowed combined energy efficiency ratio for the basic model.

[81 FR 45402, July 14, 2016]
(a) If DOE determines a party has committed a violation of regional standards, DOE will issue a Notice of Violation advising that party of DOE's determination.
(b) If, however, DOE determines a noncompliant installation occurred in only one instance, the noncompliant installation is remediated prior to DOE issuing a Notice of Violation, and the party has no history of prior violations, DOE will not issue such notice.
(c) If DOE does not find a violation of regional standards, DOE will notify the party under investigation.
[81 FR 45403, July 14, 2016]
(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]
(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.

(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]
(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) 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]
(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]
(a) The first sample size (n_{1}) for enforcement testing must be four or more units, except as provided by § 429.57(e)(1)(i).

where x_{i} is the measured energy or water efficiency or consumption from test i, and n_{1} is the total number of tests.
(c) Compute the standard deviation (s_{1}) of the measured energy performance from the n_{1} tests as follows:
(d) Compute the standard error (s_{x1}) of the measured energy performance from the n_{1} tests as follows:
(e)
(1) Compute the upper control limit (UCL_{1}) and lower control limit (LCL_{1}) 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:
LCL_{1} EES - ts_{X}_{1}_{X}
where t is the statistic based on a 95 percent two-tailed probability level with degrees of freedom (n_{1}−1).
(2) For an energy efficiency or water efficiency standard, compare the mean of the first sample (x_{1}) with the upper and lower control limits (UCL_{1} and LCL_{1}) 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 (n_{2}) as follows:
where s_{1} 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 (n_{1} + n_{2}) 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 n_{2}, determine one of the following:
(i) If the value of n_{2} is less than or equal to zero and if the mean energy or water efficiency of the first sample (x_{1}) is either equal to or greater than the lower control limit (LCL_{1}) or equal to or greater than 95 percent of the applicable energy efficiency or water efficiency standard (EES), whichever is greater, i.e., if n_{2}≤0 and x_{1}≥max (LCL_{1}, 0.95 EES), the basic model is in compliance and testing is at an end.
(ii) If the value of n_{2} is less than or equal to zero and the mean energy efficiency of the first sample (x_{1}) is less than the lower control limit (LCL_{1}) or less than 95 percent of the applicable energy or water efficiency standard (EES), whichever is greater, i.e., if n_{2}≤0 and x_{1}≤max (LCL_{1}, 0.95 EES), the basic model is not in compliance and testing is at an end.
(iii) If the value of n_{2} 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 n_{2} for equation (6). If the value of n_{2} so calculated is greater than 21− n_{1}, set n_{2} equal to 21− n_{1}.
(4) Compute the combined mean (x_{2}) of the measured energy or water efficiency of the n_{1} and n_{2} units of the combined first and second samples as follows:
(5) Compute the standard error (S_{x2}) of the measured energy or water performance of the n_{1} and n_{2} units in the combined first and second samples as follows:
s_{1} is the value obtained in Step (c).
(6) For an energy efficiency standard (EES), compute the lower control limit (LCL_{2}) 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 s_{x2} is the value obtained in Step (e)(5).
(7) For an energy efficiency standard (EES), compare the combined sample mean (x_{2}) to the lower control limit (LCL_{2}) to determine one of the following:
(i) If the mean of the combined sample (x_{2}) is less than the lower control limit (LCL_{2}) or 95 percent of the applicable energy efficiency standard (EES), whichever is greater, i.e., if x_{2}<max (LCL_{2}, 0.95 EES), the basic model is not compliant and testing is at an end.
(iii) If the mean of the combined sample (x_{2}) is equal to or greater than the lower control limit (LCL_{2}) or 95 percent of the applicable energy efficiency standard (EES), whichever is greater, i.e., if x_{2}≥max (LCL_{2}, 0.95 EES), the basic model is in compliance and testing is at an end.
(f)
(1) Compute the upper control limit (UCL_{1}) and lower control limit (LCL_{1}) 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 (n_{1} − 1).
(2) For an energy or water consumption standard, compare the mean of the first sample (x_{1}) with the upper and lower control limits (UCL_{1} and LCL_{1}) 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 (n_{2}) as follows:
where s_{1}and 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 (n_{1} + n_{2}) 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.

(i) If the value of n_{2} is less than or equal to zero and if the mean energy or water consumption of the first sample (x_{1}) is either equal to or less than the upper control limit (UCL_{1}) or equal to or less than 105 percent of the applicable energy or water consumption standard (ECS), whichever is less, i.e., if n_{2} ≤0 and x_{1} ≤min (UCL_{1}, 1.05 ECS), the basic model is in compliance and testing is at an end.
(ii) If the value of n_{2} is less than or equal to zero and the mean energy or water consumption of the first sample (x_{1}) is greater than the upper control limit (UCL_{1}) or more than 105 percent of the applicable energy or water consumption standard (ECS), whichever is less, i.e., if n_{2} ≤0 and x_{1} >min (UCL_{1}, 1.05 EPS), the basic model is not compliant and testing is at an end.
(iii) If the value of n_{2} 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 n_{2} for equation (11). If the value of n_{2} so calculated is greater than 21−n_{1}, set n_{2} equal to 21−n_{1}.

(ii) If the mean of the combined sample (x_{2}) is equal to or less than the upper control limit (UCL_{2}) or 105 percent of the applicable energy or water performance standard (ECS), whichever is less, i.e., if x_{2}≤min (UCL_{2}, 1.05 ECS), the basic model is in compliance and testing is at an end.

(a) When testing distribution transformers, the number of units in the sample (m_{1}) 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.
(b) DOE shall determine compliance as follows:

(4) Compute the sample size discount (SSD(m_{1})) as follows:
where m_{1} is the number of units in the sample, and RE is the applicable DOE efficiency when the test is to determine compliance with the applicable energy conservation standard, or is the labeled efficiency when the test is to determine compliance with the labeled efficiency value.
(6) Compare the mean of the first sample (X_{1}) with the lower control limit (LCL_{1}) 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 not compliant and testing is at an end.
(ii) If the mean is equal to or greater than the lower control limit, no final determination of compliance or noncompliance can be made; proceed to Step (7).

Given the value of n, determine one of the following:
(i) If the value of n is less than or equal to n_{1} and if the mean energy efficiency of the first sample (X_{1}) is equal to or greater than the lower control limit (LCL_{1}), the basic model is in compliance and testing is at an end.
(ii) If the value of n is greater than n_{1}, the basic model is not compliant. The size of a second sample n_{2} is determined to be the smallest integer equal to or greater than the difference n−n_{1}. If the value of n_{2} so calculated is greater than 21−n_{1}, set n_{2} equal to 21−n_{1}.
