The inspection set forth in this specification shall become a part of the contractors overall inspection system or quality program. The absence of any i
28、nspection requirements in the specification shall not relieve the contractor of the responsibility of ensuring that all products or supplies submitted to the Government for acceptance comply with all requirements of the contract. Sampling inspection, as part of manufacturing operations, is an accept
29、able practice to ascertain conformance to requirements; however, this does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to acceptance of defective material. 4.1.2 Quality assurance terms and definitions. Reference shall be made t
30、o MIL-STD-109 to define the quality assurance terms used. 4.1.3 Inspections. Inspections shall be in accordance with MIL-A-2550 and MIL-STD-453. 4.2 Inspection provisions. 4.2.1 Lot. - 4.2.1.1 Submission of product.

31、n of lots shall be in accordance with MIL-STD-105. 4.2.1.2 Size of lot. The production lot size shall be as specified in the contract (see 6.2). 4.2.2 Examination. One hundred percent examination shall be performed for all critical defects. Examination for major and minor defects shall be performed
32、in accordance with the classification of defects. Four power (4x) magnification may be used for inspection of such defects as burr and foreign matter. When compliance with the applicable requirement is in doubt as a result of visual examination, the characteristic shall be measured or gaged to deter
33、mine acceptability. All nonconforming material shall be rejected. 4.2.2.1 Cartridge, Drawing 8593275, covering a detail of Drawing 8593873.
