MIL-DTL-83352D
4.6.2.3 Penetration test. The penetration capability of the signal through a moderately dense
jungle or forest foliage shall be demonstrated (see 6.4.2). After the signal has penetrated a
simulated jungle, it shall produce the desired display.
4.6.2.4 Jolt test. The signal shall be subjected to 1,750 impacts in 3 axially perpendicular
orientations. These impacts shall consist of half sine wave pulses having 230 ±34.5g peak
acceleration for 2.0 ±0.2 milliseconds at a pulse rate of 35 impacts/minute. After the jolt test, the
signal shall then be tested as specified in 4.6.2.1.
4.6.2.5 Jumble test. The signal shall be subjected to random impacts imparted by free-fall inside
a rotating, closed, wood (or suitable substitute) material-lined metal box. The lining shall have a
minimum thickness of 1/4 inch. The box shall be rotated at a speed of 30 ±2 rpm for a total of
3600 ±10 revolutions. After the jumble test, the signal shall then be tested as specified in
4.6.2.1.
4.6.2.6 Forty foot drop test. The signal shall be subjected to a free fall drop onto a steel plate
from a height of 40 feet measured from the lowest point of the test item to the plate. The signal
shall then be tested as specified in 4.6.2.1.
4.6.2.7 Altitude test. The signal shall be subjected to an altitude of 50,000 feet for 5 minutes.
The signal shall then be tested as specified in 4.6.2.1.
4.6.2.8 Water immersion test. The signal shall be immersed in water to a minimum depth of 11
inches for a minimum of 3 hours at a temperature of 70 ±10°F. The signal shall then be tested as
specified in 4.6.2.1.
4.6.2.9 Firing pin force (launcher) test. The launcher shall be actuated by hand, with firing pin
fully cocked, and using a test plug to simulate the signal but allowing the measurement and
recording of the firing pin force (see 6.4.3).
4.6.3 Interchangeability test. The interchangeability of parts having the same part number
within the same lots shall be demonstrated.
4.6.4
Environmental conditions tests.
4.6.4.1 Temperature and humidity tests. The signals and launchers (quantities of each as
determined in accordance with 4.3.1) shall be subjected to one 14-day series of temperature and
humidity cycles in which the signals are cycled back and forth between -65 and +160°F with a
relative humidity of 95 percent (see 6.4.4). At the conclusion of the 14-day temperature and
humidity series, 50 percent of the signals and launchers shall be conditioned at + 160 ± 5°F for a
minimum of 5 hours; the other 50 percent of the signals and launchers shall be conditioned at
-65 ±5°F for a minimum of 5 hours.
4.6.4.1.1 Low temperature test. The signals and launchers that were conditioned as specified in
4.6.4.1 at -65 ±5°F shall be fired as specified in 4.6.2.1 within 30 seconds after removal from
