After performing the drop test on all warheads, each round shall
be x-rayed or fluoroscope. A visual examination shall be

If no safety hazard is noted, the warheads will be removed from
the boxes and placed on an approved package tester in their fiber
containers for the loose cargo test. The warheads shall not be
tied down in any manner inside the tester. The warheads shall be
equally divided and temperature conditioned to -50F 5F,
70F 15F, and 160F 5F. The conditioning time shall
be 8 hours minimum and 24 hours maximum. The tester shall then be
vibrated for 30 minutes at a frequency of 5.0 hertz at 1.3 g's.
