MIL-PRF-31031B
3.15 Connector durability. When connectors are tested as specified in 4.6.12, they shall show no
evidence of severe mechanical damage and the coupling device shall remain functional. Connectors
3.16 Contact resistance. When connectors are tested as specified in 4.6.13, the contact resistance of
the center contact, outer contact, and braid to connector shall be as specified (see 3.1).
3.17 Dielectric withstanding voltage. When connectors are tested as specified in 4.6.14, there shall
be no evidence of breakdown.
3.18 Vibration. When the cabled (or wired, as applicable) connector is tested as specified in 4.6.15,
there shall be no electrical interruptions exceeding 1 microsecond or as otherwise specified (see 3.1).
There shall be no evidence of visual or mechanical damage after the test, and the contact resistance of
the center contact shall not be changed by more than the specified amount (see 3.1 and 3.16).
3.19 Shock (specified pulse). When the cabled (or wired, as applicable) connector is tested as
specified in 4.6.16, there shall be no electrical interruptions exceeding 1 microsecond unless otherwise
specified (see 3.1). There shall be no evidence of visual or mechanical damage after the test and, the
contact resistance of the center contact shall not be changed by more than the specified amount (see
3.1).
3.20 Temperature cycling. When tested as specified in 4.6.17, there shall be no evidence of visual
or mechanical damage to the connector and it shall meet the dielectric withstanding voltage requirement
(see 3.17) and the contact resistance specified for the center contact shall not be exceeded (see 3.16).
3.21 Humidity. When connectors are tested as specified in 4.6.18, there shall be no evidence of
damage. Connectors shall withstand the dielectric withstanding voltage specified (see 3.17) and the
insulation resistance shall not be less than that specified (see 3.11).
3.22 Corona level. When connectors are tested as specified in 4.6.19, at the altitude and voltage
specified (see 3.1), there shall be no evidence of sustained discharge.
3.23 RF high potential withstanding voltage. When connectors are tested as specified in 4.6.20, there
shall be no breakdown and the leakage current specified shall not be exceeded (see 3.1).
3.24 Cable retention force. When connectors are tested as specified in 4.6.21, there shall be no
evidence of mechanical failure, loosening, rupture, or discontinuity. The direct clamping of the cable
jacket shall not be the primary method of cable retention.
3.25 Coupling mechanism retention force. When tested as specified in 4.6.22, the coupling
mechanism shall not be dislodged from the connector and the connector shall be capable of meeting the
requirements of 3.5.1 immediately after the test.
3.26 Shielding effectiveness. When connectors are tested as specified in 4.6.23, the total leakage,
cable to cable, shall not exceed that specified (see 3.1).
3.27 RF transmission loss. When connectors are tested as specified in 4.6.24, the RF transmission
loss shall not exceed that specified over the frequency range (see 3.1).
3.28 Porosity. When gold-plated contacts are examined for plating porosity as specified in 4.6.25,
there shall be no bubbling during the 30 second observation period.
