[43 FR 10540, Mar. 14, 1978. Redesignated at 46 FR 63203, Dec. 31, 1981] § 52.38c Statistical sampling procedures for lot inspection of processed fruits and vegetables by attributes. (a) General. Single sampling plans shall be used as the lot sampling plan for attributes standards under either of the following conditions: (1) Sampling of the product shall be made during the production period. No grade will be assigned to individual sample units. One grade determination only will be made at the end of the production period for the inspection lot. (2) Sampling of the product shall be made when the inspection lot is located in a warehouse, truck, railroad car, or other similar conveyance. (b) Sample size. Samples shall be randomly selected from each inspection lot in the exact number of sample units indicated for the lot size in tables XI through XIV as applicable for canned, frozen, dried, or dehydrated fruits and vegetables. TABLE XI-CANNED OR SIMILARLY PROCESSED FRUITS, VEGETABLES, AND PRODUCTS CONTAINING UNITS OF SUCH SIZE AND CHARACTER AS TO BE READILY SEPARABLE TABLE XII-FROZEN OR SIMILARLY PROCESSED FRUITS, VEGETABLES, AND PRODUCTS CONTAINING UNITS OF SUCH SIZE AND CHARACTER AS TO BE READILY SEPARABLE TABLE XIII-CANNED, FROZEN, OR OTHERWISE PROCESSED FRUITS, VEGETABLES, RELATED PRODUCTS OF A COMMINUTED, FLUID OR HOMOGENEOUS STATE Container size group Group 1: Any type of container of 1 lb or less. Group 2: Any type of container exceeding 1 lb. but not exceeding 60 oz. Group 3: Any type of container exceeding 60 oz but not exceeding 10 lb. Group 4: Any type of container [Lot sample size] Lot size (number of containers) 29 TABLE XIV-DEHYDRATED (LOW-MOISTURE) FRUITS, AND VEGETABLES 29 23,401-50,400 7,801-16,800 50,401-87,000 16,801-29,000 Group 2: Any type of container over 1 lb but not over 6 lb net weight. Group 3: Any type of container over 6 lbs. Lot inspection: Sample size (number of sample units). (c) Determining compliance. (1) An inspection lot meets the requirements of a quality grade if the number of defects (or defectives) is equal to or less than the acceptance numbers of all classes of defects. (2) An inspection lot fails the requirements of a quality grade if the number of defects (or defectives) exceeds the acceptance number for one or more classes of defects. (d) Lot single sampling plans for processed fruits and vegetables. (1) Tables XV through XIX contain the lot single sampling plans for each of five different standard sample unit sizes. The plans within each table are listed according to increasing values of Acceptable Quality Levels (AQL's). 157-010 0-95-3 (2) AQL values of 10.0 or less may be expressed either in "defects per hundred units" or in "percent defective units." The same sampling plans are used for both. Separate sampling plans must be used for AQL values greater than 10.0. (3) A separate lot single sampling plan is chosen for each class of defects (or defectives) by first specifying the desired AQL, the appropriate standard sample unit size, and the number of sample units as specified in §52.38c (b) of this subpart. The quality levels associated with the Pa-50% and Pa=10% levels are given in the instructional manual.

Redesignated at 46 FR 63203, Dec. 31, 1981] $52.39 Issuance of certificate of sampling. Each inspector and each licensed sampler shall prepare and sign a certificate of sampling to cover the samples drawn by the respective person, except that in-plant inspectors who inspect the samples which they have drawn need not prepare a certificate of sampling. One copy of each certificate of sampling prepared shall be retained by the licensed sampler and the original and all other copies thereof shall be disposed of in accordance with the instructions of the Administrator. [51 FR 20445, June 5, 1986] $52.40 Identification of lots sampled. Each lot from which officially drawn samples are selected shall be marked in such manner as may be prescribed by the Administrator, if such lots do not otherwise possess suitable identification. |
