In this test, a contaminate liquid is slowly dripped between two electrodes on the surface of the material. By adding this contamination, electrical conduction between the two electrodes is started and carbonization of the polymer slowly occurs. Once the carbonization occurs and the electrical current exceeds the threshold set on the test, the test is halted, and the voltage is decreased. This continues until sufficient amount of data is gathered to interpolate the number of contaminate drops necessary to achieve the electrical current threshold.

The dielectric is perhaps one of the most referenced tests when examining wires. The reason is that it tests the most important part of the wire insulation: determine if the wire insulation is free of breaches (or has been sufficiently degraded such that a high voltage would breach any weak points in the insulation). The basics of the test are that the entire wire, except for an inch at both ends, is placed in a water bath (with salt and wetting agent) and a high voltage potential is placed between the conductor and the return electrode in the water bath. If there is a failure in the insulation, then there will be a noticeable current flow. Dependent on the test method used, the pretest soak time, voltage amplitude and type (AC or DC) will vary.

For
Wire

The thermal index test (also known as the Relative Thermal Life and Temperature Index) is based on multiple cycles of elevated temperature exposure, mechanical stressing, and electrical insulation integrity checks. The goal of this test is to determine the maximum continuous operational temperature for the wire/cable for a targeted time interval (the common goal for aerospace wires is to find the maximum continuous temperature for 10,000 hours of operation). This is achieved with long-term exposure to temperatures above this desired temperature rating.

Insulation

The wrap back examines a wire/cable's insulation susceptibility to breach when tightly wrapped around itself and exposed to elevated temperatures. This test is usually required in the individual wire specifications as part of the insulation integrity assessment. After the elevated temperature exposure, the specimen is visually examined for any insulation cracks (or delamination in the case of tape wrapped insulations). The insulation integrity is then examined with a wet dielectric test.
