3.4.4 Temperature. The gyro-pendulum shall be capable of conforming
to the requirements of this specification at any temperature within the
limits of Table V, in the unit conditions specified in Table V.
-45 to +140 degrees F
O to +140 degrees F
Ready and operating
O to +160 degrees F
3.4.5 Pressure. The gyro-pendulum shall be capable of withstanding a
pressure of 2.7 psia.
3.4.6 Humidity. The gyro-pendulum shall withstand exposure to 95
percent relative humidity at 110 degrees F for eight hours without degra-
dation of the finish or functional capabilities.
3.4.7 Storage orientation sensitivity. The rms static null signal
output of each of the five instruments (see 6.1.2) shall not exceed 100
millivolts (rev) after the gyro-pendulum has been stored in any 90 degree
pitch or roll orientation for one year. Conformance shall be demonstrated
by a 48 plus or minus 1 hour storage test made at any time during the
one year storage period.
