MIL-PRF-39016/27F
Qualification inspection (reduced testing for previously qualified relays) for relays supplied with spreader mounting
pads (-031 through -036), two (2) units of the 26.5 volt rated coil voltage (-036) shall be tested as specified below:
Before 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:
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), and screening.
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 (latch/reset)
value (voltage), 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 spreader mounting pads (-031 through -036), shall be tested as specified
below:
Perform seal test immediately, preceding the A2 electrical tests. Relay leads shall be formed and the spreader
mounting pad removed before the seal test. After the seal test, the spreader mounting pad shall be rigidly
attached to the relay and the remaining group A tests performed.
Qualification inspection (reduced testing) and sample size: See table III.
If the relays produced for MIL-PRF-39016/27 are similar in construction and design except for the contact
arrangement, diodes, and headers, as applicable to the relays produced for MIL-PRF-39016/28, /29, and/30,
then reduced testing for qualification of MIL-PRF-39016/27 relays may be performed concurrent with or
subsequent to successful qualification of MIL-PRF-39016/28, /29, and /30. For reduced testing, see table III.
