PETN from one batch or blending of batches wh-ch results Inspection lots shall comply with Standard MIL-STD-105 and shall be numbered in accordance with Standard MIL-
40、STD-1168. Unless otherwise approved by the contracting officer, the inspection lot size of major assemblies or end items deliverable under the contract shall be not less than the smallest weekly estimate of quantities contractually scheduled for production during the contract period, nor more than t
41、he largest quantity contractually scheduled fcr delivery during any month of the contract period.

43、otection afforded the Government by the sampling plans in Standard MIL-STD-105. Continuous sampling plans in accordance with Standard MIL-STD-1235 for defects other than critical may be used if approved by the procuring activity. Also, at the option of the procuring activity Aals and sampling plans
44、may be applied to the individual characteristics listed using an AQL of 0.40 percent for each major defect and an AQL of 0.65 percent for each minor defect. performance of the inspections listed shall be in accordance with 4.3.4.
