Not applicable
1/ For sampling plan, unless otherwise specified, see MIL-PRF-19500.
2/ For resubmission of failed subgroup A1, double the sample size of the failed test or sequence of tests. A failure in
group A, subgroup 1 shall not require retest of the entire subgroup. Only the failed test shall be rerun upon
submission.
3/ Separate samples may be used.
4/ Not required for JANS devices
5/ Not required for laser marked devices.
