scope:

1.1 This specification covers extruded crosslinked and thermoplastic semi-conducting, conductor and insulation shielding materials for electrical wires and cables.

1.2 The materials covered are not compatible with hydrocarbon derivatives of a swelling or deteriorating nature.

1.3 Whenever two sets of values are presented, in different units, the values in the first set are the standard, while those in parentheses are for information only.

1.4 In many instances, the electrical properties of the shielding material are strongly dependent on processing conditions. For this reason, in this specification the material is sampled from cable. Therefore, tests are done on shielded wire in this standard solely to determine the relevant property of the shielding material and not to test the conductor or completed cable.
