§160.026-6   Sampling, inspection, and tests of production lots.

(a) General. Containers of emergency drinking water must be tested in accordance with the provisions of this section by an independent laboratory accepted by the Coast Guard under 46 CFR 159.010.

(b) Lots. For purposes of sampling the production of approved emergency drinking water for lifeboats and life rafts, a lot shall consist of all cans of water to be offered for inspection at one time. Lots shall be numbered serially by the packer, and a new lot shall be started with any change or modification in materials or production methods.

(c) Visual inspection of containers. The independent laboratory inspector shall select at random from each lot the number of sample filled containers indicated in table 160.026-6(c), which shall be examined visually for compliance with the requirements of this subpart. If the number of defective cans exceeds the acceptance number shown in the table for the samples selected, the lot shall be rejected.
