MIL-I-602848
4.2.3.4 Initiator pin security. The initiator pin of each subassembly 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 subassembly.
4.2.3.5 Functional tests. The following tests shall be performed by the Government.
4.2.3.5.1 Ballistics. Twenty-one units shall be tested to determine compliance with 3.8. The units shall be temperature conditioned as provided in table II and 4.3.6.2. Failure of any unit to comply with 3.8 shall be cause for rejection of the lot.
TA8LE II. Conditioning temperature.
4.2.3.5.2 Retest. There shall be no retests.
4.2.3.5.3 Test failure. If a test failure is attributable to an assignable cause, excluding the test initiator, the original test results shall be discarded and that test reconducted.
4.3 Test methods and procedures.
4.3.1 Breakawaytorque. Thetorquewrenchsetasspecifiedin3.3shallbeused inconjunction with a fixture to determine the adequacy of the joints. The chamber shall be secured in an air vise, and the torque shall be applied to the cap.
4.3.2 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 inchesfromtheend and atthe same height as the compass, in the north-south horizontal position (cap end atsouth) withthecompasssetinaneast-west heading. The assembly shall be moved at a speednogreaterthan10feetperminutepastthecompassforitsentirelength,rotated90degrees 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.
4.3.3 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.
4.3.4 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.
