MIL-DTL-12883F
f.
Points of application:
(1)
Connect all contacts together.
(2)
Connect all metallic parts (except contacts) of the socket together.
(3)
Measure between all contacts (tied together), and the metallic parts of the socket (tied
together), with the positive test probe on the contacts.
g. After testing sockets shall meet the requirements of 3.5.3.
4.7.4.2 High altitude. Unless otherwise specified (see 3.1), sockets shall be tested as specified in 4.7.4,
while being maintained at a barometric pressure simulating an altitude of 50,000 feet (i.e. 87 torr). The
following details and exceptions shall apply:
a. Period of time at reduced pressure prior to application of dielectric potential: Long enough for all
entrapped air in the chamber to escape.
b. Dielectric potential: As specified (see 3.1).
c.
Duration of application of test voltage: 60 seconds.
d. Points of application:
(1) Connect all odd-numbered contacts together.
(2) Connect all even-numbered contacts together.
(3) Measure between the odd-numbered contacts (tied together) and the even-numbered contacts
(tied together).
e. After testing sockets shall meet the requirements of 3.5.3.
f.
Points of application:
(1) Connect all contacts together.
(2) Connect all metallic parts (except contacts) of the socket together.
(3) Measure between all contacts (tied together), and the metallic parts of the socket (tied
together), with the positive test probe on the contacts.
g. After testing sockets shall meet the requirements of 3.5.3.
4.7.5 Gauge retention (see 3.5.4). Appropriate gauge retention by each contact of the socket under test
shall be determined by using the applicable contact-retention test gauge (see appendix). The probe end of
the gauge shall be inserted into and withdrawn from the particular contact three times; the test end of the
gauge shall then be inserted into the contact, and the socket shall be so held that the gauge is in a pendant
position under the socket. After testing sockets shall meet the requirements of 3.5.4.
