MIL-PRF-85676A(AS)
3.10 Human engineering. The design for user and maintainability requirements shall be
in accordance with MIL-STD-1472.
3.11 Dynamic crash loads. The light element(s), control unit, and mounting hardware
shall withstand loads occurring in crashes experiencing 20g upward, downward, forward, and
backward directions and 10g sidewards.
3.12 Environmental testing. The lighting subassembly shall operate after exposure to the
following environmental conditions or extremes (see 4.5.2).
a. A hot temperature extreme of 71 °C (160 °F).
b. A cold temperature extreme of -39 °C (-39 °F).
c. Concurrent high humidity and temperature extremes of 95 percent and 65 °C (149 °F),
respectively.
d. Repeated shock pulses of 11g's for 20 milliseconds.
e. A low atmospheric pressure equivalent to an altitude of 4,569 meters (15,000 feet).
f. Vibration as specified in 4.5.2.6.
g. Salt fog as specified in 4.5.2.5.
h. Conditions conducive to the growth of fungus as specified in 4.5.2.4.
i. Lighting subassembly shall operate in water ranging in temperature
from -1 °C to + 40 °C (30 °F to 104 °F).
j. In air ranging in temperature from -1 °C to 71 °C (30 °F to 160 °F).
3.13 Electromagnetic interference (EMI). The subassembly shall comply with the
requirements of MIL-STD-461. The lighting subassembly shall be considered susceptible to
EMI if the light elements become illuminated when subjected to the susceptibility signal. This
requirement shall apply whether the illumination is momentary (transient) or permanent in nature
(see 6.10).
3.13.1 Susceptibility limits, The subassembly shall be tested to determine compliance
with the following sections of MIL-STD-461.
a. CS114 Conducted Susceptibility, Bulk Cable Injection, 10 KHz to 200 MHz.
b. CS115 Conducted Susceptibility, Bulk Cable Injection, Impulse Excitation.
