# §42.107. Lot acceptance criteria.

- (a) The acceptability of the lot is determined by relating the number and class of defects enumerated on the worksheet to the acceptance and rejection numbers shown in [§§ 42.109 through 42.111](/cfr/7/42.109..42.111.md) for the respective sample size and Acceptable Quality Level (AQL).
- (b) Unless otherwise specified, use the following AQL's for the respective class of defects:
- (c) Refer to the appropriate sample size and AQL and compare the number of defects found in the sample with the acceptance (Ac) and rejection (Re) numbers in the sampling plan.
  - (1) Accept the lot after examining the single sample or first sample of a double sampling plan when all of the following conditions are met:
    - (i) The number of critical defects does not exceed the applicable acceptance number (Ac) for critical defects, and
    - (ii) The number of major defects does not exceed the applicable acceptance number (Ac) for major defects, and
    - (iii) The total number of critical, major, and minor defects does not exceed the applicable acceptance number (Ac) for total defects.
  - (2) Reject the lot after examining the single sample or first sample of a double sampling plan when any one or more of the following conditions occur:
    - (i) The number of critical defects equals or exceeds the applicable rejection number (Re) for critical defects, or
    - (ii) The number of major defects equals or exceeds the applicable rejection number (Re) for major defects, or
    - (iii) The total number of critical, major, and minor defects equals or exceeds the applicable rejection number (Re) for total defects.
  - (3) If the lot can neither be accepted nor rejected on the first sample, when a double sampling plan is used, select and examine the prescribed second sample. Accept the lot if the accumulated defects of the first and second sample meet conditions of [paragraph (c)(1)](#c-1) of this section, otherwise, reject the lot.
