Lots shall be submitted for inspection in accordance with Standard MIGSTD- 105D (or Standard MIGSTD-1235, when applicabl
24、e). Each lot shall contain: (a) Primers of one lot interfix number from one manufacturer. (b) Black powder of one lot interfix number from one manufacturer. 4.2.2 Examimt;orl. Sampling plans and procedures for the following classifications of defects shall be in accordance with Stand- ard MIL-STD-10
25、5D except that inspection. for critical defects, when listed, shall .be 100 percent. Continuous sampling plans in ac- cordance with Standard MIGSTD-1235 may be used if approved by the procuring activ- ity. Also, at the option of the piocuring ac- tivity, AQLs and sampling plans may be applied to the
26、 individual characteristics listed using an AQL of 0.25 percent for each major defect and an AQL of 0.40 percent for each minor defect.
