3.5.3 Temperature/humidity cycling. The cartridge shall be
safe to store and fire (no critical defects as defined in Table
IV) after being subjected to a 4-day temperature/humidity cycle.
The reliability of the cartridge shall not degrade by more than
0.05 (see 6.8.2) and the cyclic rate shall not change by more
than 15 percent after being subjected to the temperature/humidity
cycle.
3.5.4 Long-term high termperature. The cartridge shall be
safe to store and fire (no critical defects as defined in Table
IV) after being subjected to 120 days continuous heating at 50C
(125F). The reliability of the cartridge shall not degrade by
more than 0.05 (see 6.8.2) and the cyclic rate shall not change
by more than 15 percent when the cartridge is subjected to con-
tinuous heating.
3.5.5 Long term low temperature. The cartridge shall be
safe to store and fire (no critical defects as defined in Table
IV) after being subjected to 30 days continuous cooling at -40C
(-40F). The reliability of the cartridge shall not degrade by
more than 0.05 (see 6.8.2) and the cyclic rate shall not change
by more than 15 percent when the cartridge is subjected to
continuous cooling.
3.5.6 Rough handling. The cartridge shall be safe to store
and fire (no critical defects as defined in Table IV) when sub-
jected to rough handling. The cartridge shall remain waterproof
and the reliability of the cartridge shall not degrade by more
than 0.05 (see 6.8.2) when subjected to rough handling.
3.5.7 Toxic fumes. The toxic fumes produced by the
cartridge shall be acceptable to the Surgeon General for the
applicable training scenarios and shall not exceed those produced
by firing similar quantities of 5.56mm, Ball M193 ammunition.
