Thermal shock.
a. The fuze shall be subjected to the Thermal Shock Test in
accordance with MIL-STD-331, Test 113. These fuzes shall then be
centrifuge fired. The fuze shall be charged to the nominal 600 msec
time before arming. After arming, the sensor probe should be
activated and the fuze fired. Any fuze that does not meet test
requirements shall be classified defective.
b. The Module shall be subjected to the Thermal Shock Test in
accordance with MIL-STD-331, Test 113. These modules shall then be
subjected to the timing test as specified in Table VI. Any module
that does not meet the test requirements shall be classed
defective. One defect shall be cause for lot rejection.

requirements shall be classed defective.
4.5.31 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 line for
further assembly. The S&A failing the requirement shall be classed
defective.
4.5.32
Pull-off test of switch cap. Secure the setback
weight in a holding fixture. An axial pull of 2 pounds minimum
shall be applied to the switch cap. Any separation of switch cap
from the switch insulator of 0.001 inch or more shall classify the
unit as defective.
4.5.33 Pull-off test of switch assembly. Secure the setback
weight in a holding fixture. An axial pull of 5 pounds minimum
shall be applied to the switch insulator. Any separation of switch
insulator from the setback weight of 0.001 inch or more shall
classify the unit as defective.
