34、y of units from which the sample was drawn and shall not be construed to represent any prior or subsequent quantities presented for inspection. Homogeneity shall be considered to exist provided the inspection lot has been produced by one manufacturer, in one unchanged process, in accordance with the
35、 same drawing, same drawing revision, same specification and same specification revision, and complies with the provisions for submission of product as specified in MIL-STD-105. Changes to process, specification, or drawing not affecting safety, perform- ance, interchangeability, or storage, as dete
36、rmined by the Government, shall not be deemed to alter the homogeneity of an inspection lot. All material submitted for inspection in accor- dance with this specification shall comply with the homogeneity criteria specified herein regardless of the type of sampling procedure which is being applied t

Inspection for critical defects (and major defects
40、, when so specified) shall be 100 percent. Sampling plans for major and minor defects shall be in accordance with MIL-STD-105 except that continuous 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
41、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 defect and an AQL of 0.65 percent for each minor defect. When this method is elected, it shall be applied to all of the major and minor defects listed in the
42、applicable subparagraph of this section, except where 100 percent inspection is specified, and be documented as part of the contractors inspection system. performance of the inspections listed shall be in accordance with 4.3.4.
