The sample selected shall represent only that quantity of units from which the sample was drawn. and shall not be construed to represent any prior or subsequent . . quantities
28、 presented for inspection. Homogeneity shall be con- . sidered to exist provided the inspection lot has been produced . -. . by one manufacturer, in one unchanged process, in accordance with the same drawing, same drawing revision, same specificatidn and same specification revision and complies with
29、 the provisions . 1. for submission of product as specified in MIL-STD-105.

Sampling plans for major and minor defects shall be in accordance with MIL-STD-105 except that continuou
33、s sampling plans in accordance with MIL-STD-1235 may be used if approved by the Government. Instead of applying the AQLs designated herein to the groups of major and minor defects listed, the contractor may elect to apply AQLs to individual de- fects using an AQL of 0.40 percent for each major defec
34、t and an AQL of 0.65 percent for each minor defect. When this metnod is elected, it shall be applied to al1 of the major and minor defects listed in the applicable subparagraph of this section, except where 100 percent inspection is specified, and be documented as part of the contractors inspection
