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 1C (f
