MIL-C-70724(AR)
5.2.3 Tests.  In order to insure packaging performance,
tests as identified below from drawing 8837375 shall be performed
on the outer package by the contractor and witnessed by the
Government.
5.2.3.1  Temperature conditioning.  Tests shall be performed
at +160, +70F (ambient) and -65F.  Except for +70F, the
packaged-ammunition shall be conditioned for a minimum of 16 hours
immediately prior to each test.  During the performance of the
test the temperature requirement shall be met by (a) using
portable conditioning equipment where the ambient air temperature
is maintained for the duration of the random vibration tests or
(b) conditioning the items and testing as quickly as possible
after removal from the conditioning chamber to maintain the
specified temperature level as close as possible to the required
level for loose cargo and the shock tests.
5.2.3.2  Test sample.  Twelve loaded boxes (outer packages)
shall be considered a test sample.  Unless otherwise specified, at
each temperature, two boxes will be subjected sequentially to
random vibration tests (figures 1, 2, and 3 in Appendix E) on
three mutually perpendicular axis and tests 2 (free fall drop), 13
(seven foot drop) and 14 (loose cargo) in accordance with drawing
8837375.  The remaining six boxes will be subjected to a forty
foot drop test, test 12, in accordance with drawing 8837375 with
two boxes dropped at each temperature.  Orientation of the boxes
for the test shall be as specified on drawing 8837375.
Criteria for passing tests.
5.2.3.3
5.2.3.3.1 Physical condition.  At the conclusion of the
random vibration tests, test 2, test 13 and test 14, the packaged
ammunition shall be safe to handle and operable.  The decision
that the ammunition has not met or failed to meet "safe and
operable" is based upon the firing of the ammunition in the
applicable weapons.  Mechanical or physical damage to the
ammunition which precludes the normal function of the ammunition
is cause for rejection.  The package (container) shall not spill
its contents, must be capable of being handled, stacked, stored
and must not compromise ammunition protection.  However, minor
damage to the exterior container:  loose nails, split wood, bent
box hardware, dents in fiber/metal container, etc., are
permissible and are not cause for container rejection.
