Hum idity
Non-operating
Five cycles (120 hours) o f Mil-
Std-202C, Method 106B. O m it
freezing and vibration. A llo w 24
hour post-test drying period at
+25°C ±5 °C and 30% to 80%
relative hum idity. L im it maxi­
mum temperature to +60° C if
tested w ith batteries.
Vibration
Operating and non­
operating
15 minutes along each o f the
three major axes at a total dis­
placement o f 0.025-inch peak to
peak (3.9 g at 55 c/s) w ith fre­
quency varied from 10-55-10 in
one minute cycles. Hold at any
resonant point, or if none, at 55
c/s fo r three minutes on each
axis.
Shock
Operating Two guillotine-type shocks o f 30
g, one-half sine, 11-millisecond
duration each direction along
each major axis. Total o f 12
shocks.
Non-operating One guillotine-type shock o f 60
g, one-half sine, 11-millisecond
duration in each direction along
each major axis. Total o f six
shocks.
Electromagnetic Inter­
ference (EMI) As Test­
ed in Mil-I-6181D
Radiated interference Interference radiated from the
instrument under test w ithin the
given limits from 150 kilohertz
to 1000 megahertz (w ith mesh
CRT filte r installed).
Conducted interfer­
ence
Interference conducted out o f
