4. 5.23.4 Defect identification. Identification of defects as
non-arm failures, arming time safety failures, arming time under
minimum failures will depend on both centrifuge testing and
umbilical continuity examination. In addition, items with these
failures shall be removed and not subjected to the firing test.
4. 5.23.5 Electrical inspection of fuzes. All fuzes which are
not classed as a failure shall be electrically inspected prior to
firing for umbilical continuity.
4. 5.23.6 Test equipment failure. If the test equipment fails
to produce an arming readout (i.e., recording paper skewes, audio
pick-up, or amplifier inoperative) during the arming time test as
verified by the Government, the Safety and Arming Device shall be
visually inspected for arming; if found to be armed or partially
armed, the Safety and Arming Device shall be reset into the unarmed
position, reassembled into the same fuze body, and retimed once as a
fuze. The only handling action performed on the Safety and Arming
Device shall be the reset of the device just prior to the arming
time test. The timing record produces by the fuze on the approved
fuze timing equipment shall be considered the timing record of the
fuze under the applicable defect classification.
4. 5.23.7 Rounding of fuze arming times. Fuze arming times, if
recorded to the thousandth of a second shall be "rounded off" to the
nearest hundredth of a second. Example:
Cold temperature
Ambient and hot temperature
.625 shall be .62
.625 shall be .62
.626 shall be .63
.626 shall be .63
1.074 shall be 1.07
0.874 sjall be 0.87
0.875 shall be 0.88
1.075 shall be 1.08
1.254 shall be 1.25
1.654 shall be 1.65
1.266 shall be 1.26
1.655 shall be 1.66
1.605 shall be 1.60
2.005 shall be 2.00
1.606 shall be 1.61
2.006 shall be 2.01
