This specification covers crosslinked chlorinated polyethylene compounds intended for use as jacket materials (outer coverings) on electrical wires and cables for general-purpose, heavy-duty, and extra-heavy-duty service. The materials under this specification, however, are not recommended for applications with very low temperature service requirement. Physical tests shall be performed and shall conform to the physical property requirements specified such as tensile strength, tensile stress at elongation, elongation at rupture, and tension set. Per service requirement, additional tests for sunlight and weather resistance shall be performed as well, and shall conform to the tensile strength and elongation requirements specified.

1.1 This specification covers crosslinked chlorinated polyethylene (CM) compounds suitable for use as outer coverings or jackets on electrical cables for general-purpose, heavy-duty, and extra-heavy-duty service.

1.2 These jacket materials are not recommended for use on cables which are to be installed at a temperature less than − 25°C.

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.
