4.4.8 Arming and detent functioning. - The S&A in the safe
position shall be assembled to the test equipment in accordance
with 4.3.4. The equipment shall accelerate the safety and arming
device to 20.75 g's maximum for a minimum of 3 plus 1, minus 0
seconds in a direction which simulates rocket launch. At the
completion of acceleration, the equipment shall be halted and
visual observations shall be made for the locking position of
the detent. Finger tip pressure shall be applied to the rotor
to rotate in the safe direction to ascertain positive arming.
At the completion of the test the safety and arming device shall
be returned to the safe position.
WARNING: This test may be dangerous and should be performed
behind a suitable barricade.
4.4.9 Setback weight return capability.- The loaded safety
and arming device shall be assembled to the test fixture in accor-
dance with 4.3.4. A force of 20 lbs shall be applied equally to
the two top surfaces of the setback weight toward the base of the
rotor housing, and then released. Observation shall be made for
setback weight return to the original fully safe position.
4.4.10 Rotor reset capability. - The loaded S&A shall be
assembled to the test fixture in accordance with 4.3.4. The
rotor shall be rotated to a position at least 26 degrees but not
more than 35 degrees from the fully safe position and released.
Observation shall be made for rotor return to the fully safe
position.
4.4.11 S&A Arming Time. - The loaded S&A with the g-weight
in the downward position shall be assembled to the test equipment
in accordance with 4.3.4. The equipment shall accelerate the
safety and arming device in a clockwise direction to 27.00 g's
plus or minus 0.25 g's and the arming time shall be recorded to
the nearest hundredth of a second using a calibrated timer.
4.4.12 S&A Non-Arming. - The loaded S&A with the g-weight
in the downward position shall be assembled to the test equipment
in accordance with 4.3.4. The equipment shall accelerate the
safety and arming device in a clockwise direction to the 11.25 g's
minimum for a minimum of 3 seconds. Observation shall be made
for rotor in the safe position.
4.4.13 Fuze Arming Time. The fuze assembly with the g'weight
in the downward position shall be assembled to the test equipment
in accordance with 4.3.4. The equipment shall accelerate the fuze
in a clockwise direction to 27.00 g's plus or minus 0.25 g's and
the arming time shall be recorded to the nearest hundredth of
a second using a swing fixture and acoustic pick-up feeding the
arming cycle noise signal to a design agency approved recorder.
