TABLE I. Dash numbers and operating characteristics.
Frequency-temperature tolerance (one-half temperature cycle, referenced to frequency measured at +23
C
1C, immediately prior to starting of the test): See table I. Measurements taken at ten equally spaced increments
over the specified operating temperature range. 1/
Frequency-voltage tolerance:
1 ppm maximum for a 10 percent change in supply voltage. Measurements taken
at reference temperature and operating temperature range end points.
Frequency aging: Measurements shall be taken at +70
C 0.2C at intervals of not more than every 72 hours for a
minimum of 30 days.
5 ppm per year, maximum 10 ppm per year, maximum
0.7 ppm per 30 days. 1.5 ppm per 30 days
1.5 ppm per 90 days 3 ppm per 90 days
Terminal strength:
Method 211 of MIL-STD-202 , test condition C.
Applied force: 2 pounds each terminal for 10 seconds.
Bends: Five at 45 degrees each.
Frequency-environmental tolerance: Not applicable.
Vibration, sinusoidal: In accordance with
MIL-PRF-55310 and method 204 of MIL-STD-202 .
Nonoperating: Test condition D.
Operating: Not required.
Ambient pressure:
Nonoperating: In accordance with
MIL-PRF-55310 .
Operating:
Method 105 of MIL-STD-202 , test condition C.
1/ For the purpose of transitioning this device to
MIL-PRF-55310 , ‘Frequency stability versus temperature’ has been
renamed ‘Frequency-temperature tolerance’. The verification requirements of ‘initial frequency-temperature
accuracy (one-half temperature cycle)’ shall apply except that frequency measurements shall be referenced to
the frequency measured at +23
C 1C (f
ref
) instead of to the nominal frequency (f
nom
).
