MIL-DTL-82909A (OS)
4.3.8 Shock test. The battery packs with protective plugs installed on the inlet ports and electrical
connectors, shall be submitted to the shock test outlined in MIL-STD-810D, Method 516, Procedure I with
the following requirements:
a. The shock pulse wave form shall be terminal peak sawtooth. The peak amplitude shall be 20g with
a duration of 11 milliseconds as shown in figure 4. Three shocks shall be applied in each direction of the
three mutually perpendicular axes orientations as shown in figure 1. Each battery pack shall be visually
inspected after each axis direction test for evidence of mechanical failure or any defects which may affect
proper installation or function. Result of inspection shall be noted.
b. Failure of any battery pack to comply with the requirements of 3.6.2 shall be cause for rejection of
the lot and/or first article.
4.3.9 Temperature-Shock/Humidity/Altitude (TSHA) cycling test. The battery packs with protective
plugs installed in the inlet and electrical ports shall be submitted to the temperature shock/humidity/altitude
cycling test outlined in MIL-I-23659 with the following requirements:
a. The battery packs shall be supported in such a way that all areas are exposed to the prescribed
atmospheric conditions at all times throughout the test. No battery pack shall be touched by another battery
pack during the cycling schedule shown in table VIII.
b. Failure of any battery pack to comply with the requirements of 3.6.3 shall be cause for rejection of
the lot and/or first article.
