ASTM D4363-21

Standard Specification for Thermoplastic Chlorinated Polyethylene (CPE) Jacket for Wire and Cable

ABSTRACT
This specification covers thermoplastic chlorinated polyethylene (CM) compounds suitable for use as an outer covering or jacket on electrical cables. Thermoplastic jackets shall conform to the requirements for physical properties specified. The sunlight and weather resistance of the jackets shall be tested to meet the requirements specified.
SCOPE
1.1 This specification covers thermoplastic chlorinated polyethylene (CPE) compounds suitable for use as an outer covering or jacket on electrical cables.  
1.2 These jacket materials are suitable for use on cables which will be installed at temperatures above –35 °C.  
1.3 The values stated in inch-pound units are 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.
