standard ambient conditions.

4.7.13 Contact Resistance (See 3.6.12). Contact resistance tests shall be performed in

accordance with MIL-C-49142, Paragraph 4.6.16.

4.7.14 Cable Retention Force (See 3.6.13). When applicable (see 3.1), the connector shall be

assembled to its mating test cable as specified in Paragraph 4.5.1. The connector shall be

firmly fixed and a movable sleeve attached to the cable. The sleeve is then moved

longitudinally away from the fixed connector gradually and in such a manner that the

cable remains unbent and un- twisted. A scale for measuring the retention force shall be

attached to the sleeve. The force shall be held for 30 seconds minimum. The assembly

shall then be examined for mechanical failure, loosening, or rupture and tested with a

suitable low voltage continuity circuit. With the connector still in the fixed position, the

cable shall be held at a distance from the connector equal to 10 times the diameter of the

cable, and a torque shall be applied in both directions as specified. The cable shall then be

bent to a radius of 10 times the diameter of the cable and a torque shall be applied in both

directions as specified. The cable shall then be bent to a radius of 10 times the diameter

of the cable, starting at the connector at an angle of 90° +5° from the axis of the

connector, then reversed 180° ± 10°. Repeat this procedure four times, then retest and re-

examine as outlined above. Test force shall be as specified on the detail specification

sheet.

4.7.15 Coupling Mechanism Retention Force (See 3.6.14). The connector body and coupling

mechanism shall be secured to the lower and upper jaws, respectively, of a tensile tester.

A tensile load shall be applied at a rate of approximately 100 pounds per minute up to 100

pounds minimum and held at that value for 1 minute. During the 1 minute of constant

applied force, the coupling mechanism shall be rotated with respect to the connector body,

two full revolutions in each direction.

4.7.16 Connector Durability (See 3.6.15). Mated connectors shall be subjected to 500 cycles of

mating and unmating at a rate of approximately 300 cycles per hour. Debris may be

shaken or blown from the threads or interface surfaces at intervals of not less than 50

cycles. Solvents or tools shall not be used for cleaning.

4.7.17 Altitude Immersion (See 3.6.16). Mated connectors shall be tested in accordance with

Method 1004 of MIL-STD-1344.

4.7.18 Contact Engagement and Separation Force (Contacts) (See 3.6.1). Socket contacts shall be

mounted in a suitable fixture for applying gradually increasing loads for the engagement

and separation of the specified test pins in accordance with Method 2014 of MIL-STD-

1344. The test pins shall be inserted and removed from each socket contact. The

engagement force shall be measured during insertion with maximum diameter pin. A

minimum-diameter test pin shall be inserted and removed from each socket contact and

the separation force shall be measured during removal.

4.7.19 Air Leakage (See 3.6.18). Terminated, mated pressure bulkhead connector assemblies

shall be tested in accordance with the environmental seal test method of MIL-STD-1344,

Method 1008. Cable attached to the connector shall be sealed and remain within the test

chamber. The test shall be conduct- ed at room temperature with a pressure differential of

1 atmosphere maintained for 30 minutes.

4.7.20 Coupling Overtorque (See 3.6.19). Terminated connector assemblies shall be mated in the

normal manner. A torque of 150% of the maximum coupling torque specified shall then be

applied to the coupling nut.

4.7.21 Ruggedness Proof Test. Terminated, mated, connector assemblies shall be subjected to

tensile loading by pulling on each cable with a force of 25 lbs. The required force shall be

maintained for one minute, following which the connectors shall be visually examined for

damage.

5. Packaging

Unless otherwise specified in the procurement document, the requirements for packaging

shall be in accordance with standard commercial practice.

6. Notes

6.1 Intended Use. Connectors and associated shielded contacts covered by this specification

are primarily intended for use with coaxial, triaxial or twinaxial cable for data

transmission applications.
