1.1 These test methods cover procedures for testing crosslinked insulations and jackets for wire and cable. To determine the test to be made on the particular insulation or jacket, refer to the product specification for that type. These test methods do not apply to the class of products known as flexible cords.
This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.2 Whenever two sets of values are presented, in different units, the values in the first set are the standard, while those in the parentheses are for information only.
1.3 In many instances the insulation or jacket cannot be tested unless it has been formed around a conductor or cable. Therefore, tests are done on insulated or jacketed wire or cable in these test methods solely to determine the relevant property of the insulation or jacket and not to test the conductor or completed cable.
1.4 The procedures appear in the following sections:
1.5 This test applies to the detection and measurement of partial discharges occurring in the following types of electric cables:
1.5.1 Single-conductor shielded cables and assemblies thereof, and
1.5.2 Multiple-conductor cables with individually shielded conductors.
1.6 Do not perform these tests on:
1.6.1 Cables which have a nonconductive separator between the conductor and the insulation,
1.6.2 Cables having insulations less than 0.045 in. (1.14 mm) thick, or
1.6.3 Insulations with coverings that are not removable without damage to the insulation.
