MIL-PRF-39016/19H
Initial qualification of relays supplied with spacer mounting pads (-037 through -042 and -049 through -054), 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 spacer 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 spacer 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 (value voltages), coil resistance, operate and release time, contact dynamic characteristics, coil
transient suppression (when specified), solderability, seal, visual and mechanical inspection (external).
Qualification inspection (reduced testing for previously qualified relays) for relays supplied with spacer mounting
pads (-037 through -042 and -049 through -054): Two units of the 26.5-volt rated coil voltage (-042) shall be tested
as specified below:
Before installation of spacer mounting pad, perform the following tests as specified in the qualification inspection
table of MIL-PRF-39016 in the order shown below:
For failure rate level L only: Screening.
For failure rate levels M, P, and R: Vibration (sinusoidal) test duration shall be 10 minutes, vibration
(random), screening.
After installation of spacer 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).
Group A testing for relays supplied with spacer mounting pads (-037 through -042) shall be tested as specified
below:
Perform seal test immediately preceding the A2 electrical tests. Relay leads shall be formed and the mounting
pad removed before the seal test. After the seal test, the mounting pad shall be rigidly attached to the relay and
the remaining group A tests performed (The seal test is not performed with group A4.
