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.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
