MIL-PRF-39016/41E
Initial qualification of relays supplied with spacer mounting pads (-049 through -056 and -065 through -072), 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 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, 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).
Qualification inspection (reduced testing for previously qualified relays) for relays supplied with spacer
mounting pads (-049 through -056 and 065 through -072) two units of the 26.5 volt rated coil voltage (-052)
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. (Failure rate level "L" is inactive for new design).
For failure rate levels M, P, and R: Vibration (sinusoidal) test duration shall be 10 minutes, vibration
(random), and 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 (-049 through -056 and -065 through -072) 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.)
