MIL-PRF-39012E
3.5.2 "Push on" connector types. When tested as specified in 4.6.2.2, the forces necessary to fully
engage or disengage the connector shall not exceed that specified (see 3.1).
3.6 Coupling proof torque. When tested as specified in 4.6.3, the coupling mechanism (threaded
types) shall not be dislodged, and the connector shall meet requirements of 3.5.1. The interface
dimensions of the connector shall remain as specified (see 3.1).
3.7 Mating characteristics. When connectors are tested as specified in 4.6.4, the mating dimensions
shall be gauged as specified and the dimensions shall remain within the specified tolerances (see
3.1).
3.8 Permeability of nonmagnetic materials. When connectors (except hermetic sealed) are tested as
specified in 4.6.5, the permeability (Mu) shall be less than 2.0. The permeability does not apply to
connector hardware.
3.9 Hermetic seal (pressurized connectors). When connectors are tested as specified in 4.6.6, the
leakage rate shall not exceed that specified (see 3.1).
3.10 Leakage (pressurized connectors). When connectors are tested as specified in 4.6.7, there
shall be no leakage as detected by escaping air bubbles.
3.11 Insulation resistance. When connectors are tested as specified in 4.6.8, the insulation
resistance shall not be less than that specified (see 3.1).
3.12 Center contact retention. When all class I connectors, and class II where applicable (see 3.1)
are tested as specified in 4.6.9, the center contacts must not be displaced from the specified interface
dimensions in the uncabled connector by the application of the specified axial force (see 3.1) in either
direction or torque.
3.13 Corrosion. When connectors are tested as specified in 4.6.10, there shall be no exposure of the
base metal on the interface or mating surface, and they shall meet the requirements of 3.5.1 or 3.5.2
as applicable.
3.14 Voltage standing wave ratio (VSWR). When connectors are tested as specified in 4.6.11, the
VSWR shall not exceed that specified over the frequency range specified (see 3.1).
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). The
following statement takes precedence over any specification sheet interpretation. The outer contact
resistance values given for steel bodied connectors are typical values and are for engineering
information purposes only.
3.17 Dielectric withstanding voltage. When connectors are tested as specified in 4.6.14, there shall
be no evidence of breakdown.
