Subject: Communications Cable Reliability
I am trying to develop a reliability test for a communications cable. The cable uses stranded wires, some of which are twisted pair and is approx 2 feet long and is installed within a piece of electronic equipment.

Aside from installing a cable in the top level assembly and testing it under vibration etc. does anybody know of a stand-alone test for a cable to qualitatively assess it's reliability and to perhaps compare it with different designs of the cable ? (i.e. create a measuring stick to determine improvements etc.)

Thanks in advance.

The primary failure mode for cables is wire breakage. Therefore, I would suggest that you could perform a bending reliability test. Repeated bends over a mandrill could show the inherent life of the cable and be used for comparison purposes.
