1/ For retention of qualification or extension of qualification to lower failure rate levels, all life test data accumulated
on MIL-PRF-39016/43 may be used in addition to MIL-PRF-39016/42 data. Prior to performance of qualification
or extension of qualification testing, the relay manufacturer shall preselect the sampling plan.
2/ The number of units required for qualification testing shall be increased as required in Q5, table II, MIL-PRF-
39016, if the relay manufacturer elects to test the number of units permitting one or more failures. Prior to
performance of qualification inspection testing, the relay manufacturer shall preselect the sampling plan.
Qualification testing (reduced testing) (sample size - 2 units each coil voltage and 1 unsealed unit). See table III.
If the relays produced for MIL-PRF-39016/42 are similar in construction and design except for the steering diode to
the relays produced for MIL-PRF-39016/43, then reduced testing for qualification of MIL-PRF-39016/42 relays may
be performed concurrent with or subsequent to successful qualification of MIL-PRF-39016/43 relays. For reduced
testing see table III.
