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.

The impulse dielectric tests can be thought of a production line means of checking for insulation/jacket breaches in wires/cables. In this test, a voltage is placed on the specimen and the specimen is pulled under a 'chain mail' curtain connected to ground.

The long-term readability of wire/cable identification is important for supporting EWIS maintenance operations. A wire/cable with an easily identifiable circuit identification will make it easier to identify the correct circuit in need of evaluation/repair/replacement. If the identification has worn off, then debugging operations may require removing more equipment and/or demating more connectors.
The marking durability test seeks to evaluate the wire/cable identification after abrasion. The pass/fail criteria are based on the individual wire/cable specification but is primarily focused the readability of the wire/cable marks.
