ASTM D4313-21

Standard Specification for General-Purpose, Heavy-Duty, and Extra-Heavy-Duty Crosslinked Chlorinated Polyethylene (CPE) Jackets For Wire and Cable

ABSTRACT
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.
SCOPE
1.1 This specification covers crosslinked chlorinated polyethylene (CPE) 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 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
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.
