This specification covers semirigid, flame-retardant, crosslinked poly(vinylidene fluoride) heat-shrinkable tubing for electrical insulation purposes. It is supplied in an expanded form and will shrink to its extruded diameter when heated. The tubing shall be extruded, crosslinked, and then expanded to the required dimensions. The material shall conform to the chemical property requirements specified. Every lot of material manufactured shall be tested for restricted shrinkage, heat shock, tensile strength, and elongation to conform to the mechanical, thermal, electrical requirements.
1.1 This specification covers semirigid, flame-retardant, crosslinked poly(vinylidene fluoride) heat-shrinkable tubing for electrical insulation purposes. It is supplied in an expanded form and will shrink to its extruded diameter when heated.
Note 1: This standard is similar but not identical to IEC 60684–3–228.
1.2 The values stated in inch-pound units are to be regarded as the standard, except temperature which shall be stated in degrees Celsius. Values in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
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.
