4.2.3 Inspection testing. 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 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 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 to
comply with the requirements of 3.5 shall be cause for rejection of the subassembly. To achieve the pull
force requirement of 18-25 pounds specified in 3.5 selective reassembly may be necessary (i.e., changing
initiator pins or springs) for those assemblies which are out of range.
4.2.3.4 Initiator pin security. The initiator pin of each subassembly consisting of all parts, except the
chamber and cartridge, 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.
4.2.3.5 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 the requirements of
3.7. The units shall be temperature conditioned as provided in table II and 4.3.5. Failure of any unit to
comply with the requirements of 3.7 shall be cause for rejection of the lot.
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 Breakaway torque. A torque wrench set at the torque requirement specified in 3.3 shall be used in
conjunction with a fixture to determine the adequacy of the, joints. The chamber shall be secured in a
suitable vise and the torque shall be applied to the cap.
