ASTM-D2308 2020

1.1 This specification covers a thermoplastic jacketing compound for 2 to 35 kV wire and cable, of at least 0.030 in. (0.76 mm) nominal thickness, consisting substantially of pigmented polyethylene.

1.2 In many instances the jacket material cannot be tested unless it has been formed around a conductor or cable. Therefore, tests done on jacketed wire and cable in this specification are solely to determine the relevant property of the jacket material and not to test the jacketed conductor or completed cable.

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 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
