MIL-PRF-55339C
3.3.4 Spring members. Unless otherwise specified (see 3.1), center contact spring members shall
be made of copper beryllium.
3.3.5 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or
environmentally preferable materials should be used to the maximum extent possible, provided that
the material meets or exceeds the operational and maintenance requirements, and promotes
economically and advantageous life cycle costs.
3.4 Configuration and features. Adapters shall be of the configuration and physical dimensions
specified (see 3.1). The nominal impedance, working voltage, frequency range, and temperature
range shall be as specified (see 3.1).
3.4.1 Mating (visual indication). When applicable, a visual means for indicating complete mating
shall be as specified (see 3.1).
3.4.2 Screw threads. Screw threads shall be in accordance with FED-STD-H28 unless otherwise
specified (see 3.1).
3.4.3 Adapter interfaces. Adapter interfaces shall be in accordance with MIL-STD-348 unless
otherwise specified (see 3.1).
3.5 Center contact retention. When adapters are tested as specified in 4.5.2, the center contacts
shall withstand the axial force specified (see 3.1). The center contact shall meet the mating interface
dimensions. When a torque requirement is specified (see 3.1) there shall be no rotation of the center
contact.
3.6 Force to engage/disengage (see 4.5.3).
3.6.1 Bayonet and threaded types. When tested as specified in 4.5.3.1, the torque necessary to
completely couple or uncouple the adapters shall not exceed that specified (see 3.1). Also the
longitudinal force necessary to initiate the engaging or disengaging cycle shall not exceed that
specified (see 3.1).
3.6.2 "Push on" adapter types (with or without detents). When tested as specified in 4.5.3.2, the
forces necessary to fully engage or disengage the adapter shall not exceed that specified (see 3.1).
3.7 Coupling proof torque (threaded adapters). When tested as specified in 4.5.4, the coupling
mechanism shall not be dislodged, and the adapter shall meet requirements of 3.6.1. The interface
dimensions of the adapter shall remain as specified (see MIL-STD-348).
3.8 Mating characteristics. When adapters are tested as specified in 4.5.5, the mating dimensions
shall be gauged as specified (see 3.1) and the dimensions shall remain within the specified
tolerances (see 3.1).
3.9 Permeability of nonmagnetic materials. When adapters (except hermetic sealed and connector
hardware) are tested as specified in 4.5.6 , the permeability (Mu) shall be less than 2.0.
3.10 Hermetic seal (pressurized adapters only). When adapters are tested as specified in 4.5.7, the
leakage rate shall not exceed that specified (see 3.1).
3.10.1 Leakage (pressurized adapters only). When adapters are tested as specified in 4.5.7.1,
there shall be no leakage as detected by escaping air bubbles.
