ASTM D3554-01

Standard Specification for Track-Resistant Black Thermoplastic High-Density Polyethylene Insulation for Wire and Cable, 75^oC Operation

SCOPE
1.1 This specification covers track-resistant black thermoplastic high-density polyethylene insulation. The base polymer of this material consists substantially of polyethylene. Before application to the conductor, the insulation shall comply with the requirements of Specification D1248, Type III, Class C, Category 5, Grade E10, J4, or J5. The requirements of Specification D1248 shall not apply to the insulation removed from the conductor.
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 75oC.
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 -25oC and exposed to sunlight and other atmospheric environments between -55 and +75oC.
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.
