MIL-C-70724(AR)
4.6 Miscellaneous acceptance criteria.
4.6.1 Chemical compatibility acceptance criteria. The
criteria will be considered met if no critical defects are
encountered and if the reliability (see 6.8) of the test cartridge
does not degrade when compared to the control sample by more than
the allowable amount for each individual weapon/chemical
configuration.
4.6.2 Function and casualty acceptance criteria for
qualification testing. In view of the expenses associated with
firing function and casualty tests with both ammunition and
weapons temperature conditioned, the following shall be employed:
a. The occurrence of any critical defect shall be cause for
rejection.
b. Function and casualty qualification testing at -65°F and
+155°F shall be conducted with both the ammunition and weapons
conditioned and fired at the test temperature. The acceptance
criteria of Table IV, for all defect classes, shall be applied to
the results of this testing.
If acceptable performance in accordance with Table IV at
-65°F and +155°F is achieved, the remainder of the funciton and
casualty tests (-25°F, +20°F and +125°F) may be conducted with
only the ammunition being temperature conditioned. The results of
these firings must meet all Table IV acceptance criteria.
d. Failure of the -65°F or +155°F firings to meet all Table
IV criteria for major or minor defects does not cause rejection,
however, requires firing a portion of the function and casualty
testing at the less extreme temperatures (-25°F or +155°F), with
both weapon and ammunition conditioned and fired at the test
temperature. This shall be accomplished as follows:
(1) Failure at -65°F will require firing 1000 rounds at
-25°F with both the weapon and the ammunition conditioned
at the test temperature.
(2) Failure at +155°F will require firing 1000 rounds
at +125°F with both the weapon and the ammunition
conditioned at the test temperature.
