1/ Figure 1 only: For retention of qualification or extension of qualification to lower failure rate
MIL-PRF-39016/21 may be used in addition to MIL-PRF-39016/15 data. Qualification to figure
1 automatically qualifies round relays to figure 2.
Figure 2 only - For retention of qualification or extension of qualification to lower failure rate
MIL-PRF-39016/21 may be used in addition to MIL-PRF-39016/15 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 testing the relay
manufacturer shall preselect the sample size.
Initial qualification of relays supplied with spreader mounting pads (-101 through -106 and -113 through -118, and -
125 through -130) 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.
