MIL-N-81604C(AS)
Lighting  Power - Input power for lighting shall require
not more than 1.4 amperes at 5 volts, a-c or d-c.
3.3.13 Cooling - Cooling required shall conform to the cooling
curves presented herein.
a Cooling
System
Failure
The AN/ASN-92(V) equipment shall contain the thermal
cutout protection necessary to prevent damage to the
equipment. Maximum temperature shall be determined
by curves generated in conformance to MIL-T-23103.
The equipment shall continue to operate for a limited
period with air conditioning system failures result-
ing in a complete loss of cooling air flow, occurring
with ambient temperatures up to 160F.Proving
that the CAINS equipment has been operating for 15
minutes (minimum) with 80F (or cooler) inlet cooling
air at specified flow rates, the equipment will con-
tinue to meet specified performance for a period of
five minutes. The equipment will also operate
yielding degraded performance for an additional 15
minutes before overtemperature controls initiate
shutdown.
3.3.14 Printed Wiring Boards - Design and construction of printed
boards shall meet the design guide of MIL-STD-275, with
the listed additions to take advantage of the simplicity of con-
struction and weight reduction provided by "fineline" circuitry:
a.
Minimum conductor width - 0.005 inches
b.
Minimum conductor spacing - 0.005 inches
c.
Minimum copper thickness of plated-through holes
0.0015 inches
d.
Plated-through holes shall be filled with solder or
filled with epoxy with properties which meet the
requirements of MIL-I-46058.
e.
Maximum 30 temperature rise at conductor hot spot.
3.4 Performance Characteristic - The given requirements apply
to both standard and extreme service conditions.
