4.5.3 Inspection testing. The following tests shall be performed in accordance with 4.6.
4.5.3.1 Hardness. Fifty units from each heat treated lot of components shall be tested for compliance
with the requirements on the applicable drawing. Failure of any unit to comply with the drawing requirements
shall be cause for rejection of the lot of components.
4.5.3.2 Hydrostatic pressure. Each chamber and cap shall be subjected to the hydrostatic pressure test.
Failure of any cap or chamber subassembly to comply with 3.4 shall be cause for rejection of the subassembly.
4.5.3.3 Firing pin release. The initiator pin and firing pin of each partial assembly shall be subjected
to the firing pin release test. Failure of any partial assembly to comply with the requirements of 3.6 shall be
cause for rejection of the partial assembly.
4.5.3.4 Initiator pin security. The initiator pin of each partial assembly shall be subjected to the initiator
pin security test. Failure of any unit to comply with the requirements of 3.6 shall be cause for rejection of the
partial assembly.
4.5.3.5 Protective finish. The number of units for protective finish tests shall be in accordance with the
applicable specification. Failure of any unit in the inspection sample to comply with the requirements of the
applicable specification shall be cause for rejection of the lot.
4.5.3.6 Residual magnetism. Each assembly shall be subjected to the test for excessive residual
magnetism specified in 4.6.6. Failure of any unit in the inspection sample to comply with the requirements
of 3.9 shall be cause for rejection of the assembly.
4.6 Test methods and procedures.
4.6.1 Hardness. Prior to the application of protective finish, a hardness tester shall be used to determine
compliance with the requirements of the applicable drawing.
4.6.2 Hydrostatic pressure. Prior to the application of protective finish, the cap and chamber shall be
mounted in a device and subjected to hydrostatic pressure to determine compliance with 3.4.
4.6.3 Firing pin release. The subassembly shall be secured in the fixture with the safety pin in place.
A pull shall be applied to the initiator pin in the longitudinal direction in conjunction with the device which
registers the amount of pull.
4.6.4 Initiator pin security. The subassembly shall be secured in the fixture with the safety pin in place.
A pull shall be applied to the initiator pin in the longitudinal direction in conjunction with the fixture which
registers the amount of pull. The test shall be performed with the safety pin in each position.
4.6.5 Protective finish. The procedures for protective finish shall be in accordance with the applicable
specification referenced on the applicable drawing.
4.6.6 Residual magnetism. The assembly shall be tested for excessive residual magnetism using an
approved compass in an area free of local magnetic effects by placing the assembly 5 inches from the end, and
