4.4 Inspection testing. The following tests shall be performed in accordance with 4.5.
4.4.1 Hydrostatic pressure. Each chamber and cap shall be subjected to the hydrostatic pressure test.
Failure of any subassembly to comply with the requirement of 3.2 shall be cause for rejection of the
subassembly.
4.4.2 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.
4.4.3 Firing pin release. The initiator pin of each subassembly shall be subjected to the firing pin release
test. Failure of any subassembly to comply with the requirements of 3.5 shall be cause for rejection of the
subassembly.
4.4.4 Initiator pin security. The initiator pin of each subassembly shall be subjected to the initiator pin
security test. Failure of any subassembly to comply with the requirement of 3.6 shall be cause for rejection of
the subassembly.
4.4.5 Residual magnetism. Each assembly shall be subjected to the test for excessive residual magnetism
specified in 4.5.5. Failure of any unit in the inspection sample to comply with the requirement of 3.4 shall be
cause for rejection of the assembly.
4.5 Test methods and procedures.
4.5.1 Hydrostatic pressure. The subassembly shall be mounted in a device using the fixture for properly
sealing all openings and subjected to hydrostatic pressure to determine compliance with 3.2.
4.5.2 Firing pin release. The subassembly shall be secured in the fixture. A pull shall be applied to the
initiator pin in the longitudinal direction in conjunction with the fixture which registers the amount of pull.
4.5.3 Initiator pin security. The subassembly shall be secured in the fixture with the initiator 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.
4.5.4 Protective finish. The procedures for protective finish shall be in accordance with the applicable
specification referenced on the applicable drawing.
4.5.5 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 at the same height as the compass, in the north-south horizontal position (cap end at south) with the
compass set in an east-west heading. The assembly shall be moved at a speed no greater than 10 feet per
