ASTM D3555-01

Standard Specification for Track-Resistant Black Crosslinked Polyethylene Insulation for Wire and Cable, 90^oC Operation

SCOPE
1.1 This specification covers a track-resistant black crosslinked polyethylene insulation, the base polymer which consists substantially of polyethylene or its copolymers. This insulation shall be carbon black pigmented.
1.2 This type of insulation is considered suitable for use on wire or cable that will be used for continuous operation at conductor temperatures up to 90oC.
1.3 This insulation is suitable for use on wire or in cable used for power transmission in overhead spaced-line service, installed at temperatures above -25o and exposed to sunlight and other atmospheric environments between -55 and +90oC.
1.4 In many instances, the insulation cannot be tested unless it has been formed around a conductor. Therefore, tests are done on insulated wire in this standard solely to determine the relevant property of the insulation and not to test the conductor or completed cable.
1.5 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.
