1/ For retention of qualification or extension of qualification to lower failure rate levels, all life
test data accumulated on MIL-PRF-39016/15, /16, /20, /21, /24, /25, and /26 may be used
in addition to MIL-PRF-39016/23 data. Prior to performance of retention 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,
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, the relay manufacturer
shall preselect the sampling plan.
Initial qualification of relays supplied with spreader mounting pads (-031 through -036), shall be tested as specified
below:
Perform the following tests as specified in the qualification inspection table of MIL-PRF-39016, in the order shown
below:
Before installation of spreader mounting pad, screening, visual and mechanical examination (internal),
thermal shock, resistance to solvents, vibration (sinusoidal), vibration (random), shock (specified pulse),
acceleration, terminal strength, magnetic interference (when specified), capacitance (when specified), coil life
(applicable to continuous duty relays only), resistance to soldering heat, salt spray (corrosion), overload
(applicable to high level relays only), life, terminal strength, and intermediate current.
After installation of spreader mounting pad perform the following tests as specified in the qualification inspection
table of MIL-PRF-39016, in the order shown below:
Insulation resistance, dielectric withstanding voltage, static contact resistance, specified pickup, hold, and
dropout values (voltages), coil resistance, operate and release time, contact dynamic characteristics, coil
transient suppression (when specified), solderability, seal, visual and mechanical inspection (external).
