MIL-DTL-12883F
3.5.1 Insertion and withdrawal force. When sockets are tested in accordance with 4.7.2, the insertion
and withdrawal force shall be as specified (see 3.1).
3.5.2 Insulation resistance. When sockets are tested in accordance with 4.7.3, the insulation resistance
shall be as specified (see 3.1).
3.5.3 Dielectric withstanding voltage (sea level and high altitude). When sockets are tested in
accordance with 4.7.4, there shall be no breakdown of insulation or flashover (see 3.1).
3.5.4 Gauge retention. When sockets are tested in accordance with 4.7.5, each contact shall retain the
fully inserted test end of the test gauge without allowing the gauge to slide in the contact (see 3.1).
3.5.5 Contact resistance. When sockets are tested in accordance with 4.7.6, the contact resistance
shall be as specified (see 3.1).
3.5.6 Torque (when specified).
3.5.6.1 Sockets with bushings or tapped extruded holes. When tested in accordance with 4.7.7.1,
bushings shall not rotate or otherwise be loosened, and the threads of the bushings or tapped extruded
holes shall not strip when subjected to the torque specified (see 3.1).
3.5.6.2 Sockets with molded-in, threaded mounting studs. When tested in accordance with 4.7.7.2,
studs must not rotate in or crack housing, and the threads shall not strip when subjected to the torque
specified (see 3.1).
3.5.6.3 Sockets with loose, threaded mounting studs. When tested in accordance with 4.7.7.3, studs
must not rotate in or crack housing, and the threads shall not strip when subjected to the torque specified
(see 3.1).
3.5.7 Vibration. When sockets are tested in accordance with 4.7.8, there shall be no evidence of any
loosening or distortion of assembled parts, no chipping or cracking of the insulator body, nor any other
damage to the socket assembly. Socket shall retain the test gauge throughout the test. There shall be no
loss of electrical continuity for a period greater than 1 microsecond. After the vibration test is completed,
the test gauge shall be fully engaged in the socket (see 3.1).
3.5.8 Mechanical shock (when specified) (see 3.1). When sockets are tested in accordance with 4.7.9,
there shall be no evidence of loosening or bending of metal parts, no chipping or cracking of the insulator
body, or any other damage to the socket assembly. There shall be no loss of electrical continuity for a
period greater than 1 microsecond.
3.5.9 Humidity. When sockets are tested in accordance with 4.7.10, they shall pass the insulation
resistance (3.5.2) and dielectric withstanding voltage (3.5.3) requirements specified (see 3.1).
3.5.10 Durability. When tested in accordance with 4.7.11, the sockets, including the contact assemblies,
shall show no evidence of cracks or breaks. They shall meet the withdrawal force requirements as
specified (see 3.1), the gauge retention requirements of 3.5.4, and the contact resistance requirements of
3.5.5.
3.5.11 Static load (when specified) (see 3.1). When sockets are tested in accordance with 4.7.12, there
shall be no evidence of any loosening of the insulator body from the saddle or bending of the saddle.
