scope:

1.1 This specification covers a crosslinked rubber insulating compound for electrical wires and cables. The polymer consists substantially of synthetic rubber.

1.2 This type of insulation is suitable for continuous operation at conductor temperatures not exceeding 75C in dry or wet locations and operating voltages not exceeding 2000 V. This insulation may have low-temperature limitations. Consult the manufacturer for specific recommendations for installation or application.

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 insulation material cannot be tested unless it has been formed around a conductor or cable. Therefore, tests are done on insulated wire or cable in this document solely to determine the relevant property of the insulation material and not to test the insulated conductor or completed cable.
