4.5.8 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 speed clip holding the detonator in the rotor. Any
speed clip that fails the requirement 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.
4.5.9 M433 S&A arming tests ambient and hot. The S&A in the
safe position shall be assembled to the test equipment in accordance
with 4.4.4. The g-weight shall be to the right when looking from
the outside of the centrifuge spin table toward the center of
rotation of the spin table. The equipment shall accelerate the
Safety and Arming Device to 40.0g's ± 0.5g's in a direction which
simulates rocket launch. The arming time shall be recorded to the
nearest hundredth of a second using a calibrated timer. At the
completion of acceleration, the equipment shall be halted and visual
observation shall be made for the locking position of the detent to
ascertain positive arming. At the completion of the test, the
Safety and Arming Device shall be returned to the safe position.
Any S&A that fails the requirement shall be classed defective and
removed from the lot.
WARNING: This test may be dangerous, and should be performed behind
a suitable barricade.
4.5.10 Setback weight return capability. The S&A in the safe
Position shall be assembled to the test equipment in accordance with
4.4.4. The S&A shall be securely held in place during a 20 pound
load test with a hold down force. The 20 pound load shall be
applied at an average rate of 300 ± 50 inches per minute to the
setback weight. It is mandatory that the setback weight maintain
contact with the 20 pound load applicator until the setback weight
fully bottoms. The 20 pound force shall then be removed. S&A's
failing to completely return to the fully safe position shall be
classed defective and removed from the lot. Defect standards for
verification of the inspection process shall be in accordance with
18.104.22.168 and 22.214.171.124. Defect standards for use with automatic
equipment shall be as follows:
a. Units with setback weights which bind when depressed and
remain in the depressed condition.
