This test is used to determine the ability of a sample’s insulation to withstand the rubbing on a similar sample in a vibrational environment. Wires/cables in close contact with one another can rub against each other causing progressive deterioration of the insulation. The impact of how quickly the insulation degrades in a wire-to-wire scenario is dependent on the inherent insulation properties as well as the particular construction. In this cable-to-cable abrasion test, the samples are rubbed together until electrical conductivity is detected between conductors (or shields) of the two test samples.

Smooth surface wire/cable insulation types tend to have a greater longevity in this test when compared to tape wrapped constructions. The uneven surface of tape wrapped constructions creates an abrasion point that accelerates the material wear.

There are several parameters that can be adjusted to the client’s particular needs, including:

  • Weight on Sample
  • Abrasion Frequency
  • Temperature

Additional information about abrasion tests can be found here.

Our Process
1
Visually examine the test sample for any defects. Record any observations.
2
Cut two samples lengths (part A and part B) and place terminals on each end.
3
Place test samples into fixture such that sample part A and part B are in intimate contact for about 1.0 inch (25mm).
4
Place the specified weight on sample part A.
5
Connect both sample parts to conduction detection test circuit.
6
Begin abrasion of samples (typically set to greater than 10Hz).
7
Once electrical conductivity is detected between the two samples, the test is completed.
8
Report the total number of cycles and test parameters.
