Each warhead shall be packed and packaged in accordance with
MIS-30862 or MIS-50263, whichever is applicable, except that dummy
2.75 Inch Rocket Motors shall be substituted. The test warheads are
to be positioned in the box with the warhead nose in one direction
and a dummy load utilized in the remaining fiber container. The
dummy load shall be located in the upper right position as viewed
from the nose end. 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.
Each box shall be dropped seven feet onto a steel plate which is
solidly supported by concrete. The orientations of the boxes on
striking are:
a. Eighteen (18) warheads (6 boxes-- 2 from each temperature
condition) warhead nose down (longitudinal axis 45 from vertical).
b. Eighteen (18) warheads (6 boxes-- 2 from each temperature
0
condition) warhead base down (longitudinal axis 45 from vertical).
No individual box shall be subjected to more than one drop. The
drop equipment and stand shall be capable of providing an unimpeded
free fall prior to striking the plate and permit rebounding. Prior
to performing this drop test, the following is necessary:
Serialize each warhead.
a.
b. X-ray or fluoroscope each round in two planes, 90
opposed. Verify all components are secure and the S&A is in the
unarmed position.
Before dropping, each packaged warhead shall be visually
c.
examined for evidence of incorrect packaging.
After performing the drop test on all warheads, each round shall
be x-rayed or fluoroscope. A visual examination shall be
performed. The first article shall be rejected if one or more
warheads are found to be not safe as a result of the effects of the
seven-foot drop test. 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.
