4.2.3.4.2 Retest. There shall be no retests.
4.2.3.4.3 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  Initiator pin security. A pull force shall be applied to the initiator pin in the
longitudinal direction in conjunction with the applicable fixture which registers the amount of
pull.
4.3.2 Breakaway torque. The torque wrench set as specified in 3.5 shall be used in conjunction
with a fixture to determine the adequacy of the joints. The chamber shall be secured in an air vise
or holding fixture. The torque shall be applied to the cap.
4.3.3 Residual magnetism. The initiator shall be tested for excessive residual magnetism
using an approved compass in an area free of local magnetic effects by placing the initiator 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 initiator 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 initiator.
4.3.4 Radiographic examination. All assembled initiators shall be radiographically examined
in accordance with MIL-STD-453, with the exception that an initiator assembly will be used for the
penetrameter. Any observable imperfections in components or assembly shall be cause for
rejection. The initiators shall be positioned for the most revealing exposure, with the long axis
of each assembly perpendicular to the rays of the X-ray machine. All initiators shall be
identified with serial numbers prior to X-ray examination. The serial numbers shall be in
consecutive order beginning withthe number 001 in each production lot. Any missing numbers are
to be identified on the X-rays. The initiators shall be arranged on trays or boards in consecutive
numericalorder,and each radiographshall carry a permanent identification of the units displayed
thereon. The radiographic plate identification shall include item nomenclature, the complete lot
number, the span of serial numbers displayed, and the contract number. The radiographs of the
entire production lot shall accompany the ballistic sample to the activity conducting the
production lot acceptance test. Defective initiators found during X-ray review are to be marked
on the X-ray prior to shipment and those defective items shall be removed from the production lot.
Film interpretation of the radiographs shall verify the presence and correct positioning of the
following parts:
a. Cartridge, delay M114
P/N 8596110
b. Firing pin
P/N 8595407
c. Chamber
