28、ecified in 4.4. 3.10 Component parts. All component parts shall meet the requirements of MIL-I-60525 or MIL-I-82767 prior to assembly. 4. VERIFICATION 4.1 Quality assurance terms and definitions. Reference shall be made to ASQ A8402 to define the quality assurance terms used. 4.1.1 Inspection. Inspe

29、ction shall be in accordance with MIL-A-2550. 4.2 Inspection provisions. 4.2.1 Lot. 4.2.1.1 Submission of product. Unless otherwise specified by the contracting officer, formation of lots and presentation of lots shall be in accordance with the “Submission of Product“ provisions of ASQ Z1.4. 4.2.1.2

30、 Size of lot. A lot shall consist of an identifiable group of assembled initiators containing metal parts assemblies produced by a homogeneous process and loaded with one lot of accepted cartridges. 4.2.2 Examination. One-hundred percent examination shall be performed for all critical defects. Exami

31、nation for major and minor defects shall be performed 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,

32、the characteristic shall be measured or gaged to determine acceptability. All nonconforming material shall be rejected.

The Following tests shall be performed in accordance with the provisions of 4.3. 4.2.3.1 Breakaway torque. Each assembly shall be subjected to the breakaway torque test of the threaded joint

44、between the cap and the chamber. Failure of any assembly to comply with the requirements of 3.3 shall be cause for rejection of the initiator. 4.2.3.2 Residual magnetism. Each initiator shall be subjected to the test for excessive residual magnetism as specified in 4.3.2. Failure of any initiator to

45、 comply with the requirement of 3.4 shall be cause for rejection of the initiator. 4.2.3.3 Firing pin release. The initiator pin of each subassembly, consisting of all parts, except the safety pin, cartridge, and chamber, shall be subjected to the firing-pin release test. Failure of any subassembly

46、to comply with the requirements of 3.5 shall be cause for rejection of the subassembly.
