4.4.4.2 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 3.3 shall be cause for
rejection of the subassembly.
4.4.4.3 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 requirements of 3.4 shall be
cause for rejection of the subassembly.
4.4.4.4 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.
4.4.4.5 Residual magnetism. Each assembly shall be subjected to the test for excessive residual
magnetism as specified in 4.5.5. Failure of any unit in the inspection sample to comply with 3.6 shall be
cause for rejection of the assembly.
4.5 Test methods and procedures.
4.5.1 Hydrostatic pressure. Prior to the application of protective finish the cap and chamber shall
be mounted in the device, using a fixture for properly sealing all openings, and subjected to the internal
hydrostatic pressure to determine compliance with the requirements of 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 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.
4.5.4 Protective finish. Test 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 (head 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 minute past the compass for its entire length, rotated 90 degrees in the horizontal position about its
longitudinal axis, and moved slowly back past the compass. This procedure shall be repeated for each 90
degree rotation of the assembly for four full passes.
4.6 Inspection of packaging. The sampling and inspection of the packaging, packing, and container
marking shall be in accordance with section 5.
