4.5.11 Torque test of rotor stop stud (eccentric pin). The
required torque shall be applied between the rotor stop stud and
gear assembly. The required force shall act on the gear
assembly. Any rotor stop stud that does not comply with the
drawing requirement shall be classed defective.
4.5.12 Load test of detonator. Apply an axial load of 5
pounds perpendicular to the rotor and in such a direction as to
test the strength of the speed clip holding the detonator in the
rotor. Any speed clip that moves more than .005 inch shall be
classed defective and the S&A removed from the lot.
WARNING:
This test may be dangerous and should be performed
behind a suitable barricade.
4.5.13 Continuity through detonator test. The S&A shall be
armed in the case and the resistance measured between terminals
three and four. The value shall be 3.5 1.5 ohms. After the
test, the acceptable S&A's shall be disarmed and returned to the
line for further assembly Any S&A failing the requirement shall
be classed defective and removed from the lot.
Any continuity measurement which passes electrical
CAUTION:
current through the detonator shall be limited to one
milliampere maximum.
4.5.14 Temperature conditioning. Prior to the centrifuge
test (4.5.15 and 4.5.16), the sample shall be conditioned for a
minimum of two hours after temperature stabilization at the
following temperatures:
4.5.15 M439 S&A non-arming test. The S&A in the safe
position and in the horizontal plane with the G-weight located in
the downward direction (closest to earth), shall be assembled to
the test equipment in accordance with 4.4.3. The equipment shall
accelerate the loaded Safety and Arming Device in a clockwise
direction to 12.0 g's minimum for a minimum of five (5) seconds.
Observation shall be made for rotor in the safe position. S&A' S
failing to comply with the specified requirement shall be classed
defective and removed from the lot.
4.5.16 M439 S&A arming time test. The S&A in the safe
position and in the horizontal plane with the G-weight located in
the downward direction (closest to earth), shall be assembled to
the test equipment in accordance with 4.4.3. The equipment shall
