4.4.4.9 Load test of bridge rivet. - Apply the required axial
load perpendicular to the inner plate and into the bridge rivet
from the side opposite the bridge. The resistive force shall act
against the inner plate.
4.4.4.10 Load test of spring stud. - Apply an axial load per-
pendicular to the rotor housing and in such a direction as to test
the assembly of the spring stud and the rotor housing. The resis-
tive force shall act against the rotor housing.
4.4.4.11 Load test of pillars. - Apply the required axial load
perpendicular to t he inner plate and in such a direction as to test
the assembly of the pillars to the inner plate and outer plate.
The resistive force shall act against the inner plate.
4.4.4.12 Torque test of rotor stop stud (eccentric pin). -
The required torque shall be applied between the rotor stop stud
and the gear assembly. The resistive force shall act on the
gear assembly.
4.4.5 Firing pin assembly push test. - The firing pin
assembly shall be assembled to the test equipment in accordance
with paragraph 4.3.4. After assembly, the required force shall
be applied at the required time rate to check the crimped area
of the assembly in meeting the requirements specified on the
drawing.
4.4.6 Corrosion resistance of anodic coating. - The testing
of the sample shall be in accordance with the procedures specified
in MIL-A-8625 except that the salt spray test shall be conducted
for 168 hours. The significant area for examination shall be the
outside surface of the specimens. The acceptance criteria shall
be:
a. The specimens shall show no more than 5 spots or pits,
none larger than 1/32 inch in diameter, except in those areas within
1/16 inch from the edges, corner, identification markings, and hold-
ing areas during processing.
b. Powdery areas or loose films in excess of 10 per-
cent of the examined surface shall be cause for rejection.
4.4.7 Load test of detonator. - Apply the required axial
load perpendicular to the rotor and in such a direction as to
test the strength of the staking of the detonator in the rotor.
WARNING: This test may be dangerous and should be performed
behind a suitable barricade.
