TABLE IV. Test details for dielectric withstanding voltage.
Points of application
Test voltage
1,000 percent 5 percent
Between case, frame, or enclosure and between all contacts
volts ac plus twice rated
in the energized and de-energized positions
voltage (or current) or the
Between case, frame, or enclosure and coil(s)
specified value 5 percent
Between all contacts and coil(s)
Between open contacts in the energized and de-energized
positions
Between contact poles in the energized and de-energized
positions (applicable to multipole relays)
4.6.7.2 At reduced barometric pressure. Relays shall be tested in accordance with method 105 of
MIL-STD-202. The following details shall apply:
a. Method of mounting: Normal mounting means.
b. Test condition: C.
c. Tests during subjection to reduced pressure: As specified in 4.6.7.1, except test voltage shall be
350 V rms unless otherwise specified (see 3.1).
d. Points of application of test voltage: All terminals to case.
e. Duration of application: 60 seconds minimum for qualification and group B and group C tests.
f. Attributes data is acceptable.
4.6.8 Electrical characteristics (see 3.10).
4.6.8.1 Static contact resistance (see 3.10.1). Relays shall be tested in accordance with method 307
of MIL-STD-202. The following details and exception shall apply:
a. Method of connection: For relays with wire-lead terminals, this measurement shall be made .125
inch (3.18 mm) maximum from the emergence of the lead from the relay.
b. Test load: 10 mA maximum at 6 V maximum (dc or peak ac).
c. Post test loads for high level life and intermediate current: Current and voltage shall be the same
as the life or intermediate current test or 100 mA maximum at 28 V dc maximum.
d. Points of measurements:
(1)
Between all normally closed mated contacts.
(2)
Between all normally open mated contacts, with the coil energized with rated coil voltage (or
current).
