MIL-PRF-39016/17H
Before installation of spacer mounting pad: Screening, visual and mechanical inspection (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, or
dropout values (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): Two (2) 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 and -049 through -054), shall be
tested as specified below:
Perform seal test immediately preceding the A2 electrical tests. Relay leads shall be formed and the spacer
mounting pad removed before the seal test. After the seal test, the spacer 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.).
