This specification applies to flexible fluoropolymer resin heat-shrinkable extruded tubing made from tetrafluoroethylene resin, copolymer of tetrafluoroethylene and hexafluoropropylene (FEP), and from perfluoroalkoxy (PFA) resin for use as electrical insulation. This specification covers three types of tubings, namely: Type I tubing, normally made by paste extrusion, and Type II and Type III tubings, normally made by melt extrusion. The finished compound shall be free of all foreign matter other than intended formulation additives. The material shall conform to the specified chemical and physical property requirements such as: (1) restricted shrinkage, (2) specific gravity, (3) longitudinal change, (4) tensile modulus at elongation, (5) volume resistivity, (6) dielectric breakdown voltage, (7) heat resistance, (8) low-temperature flexibility, and (9) melting point. The dimensional requirements after unrestrictive shrinkage such as inside diameter, wall thickness, and stock lengths are specified. The sampling and test methods to determine conformance to the specified requirements are given.

1.1 This specification applies to flexible heat-shrinkable extruded tubing made from tetrafluoroethylene resin, copolymer of tetrafluoroethylene and hexafluoropropylene, and from perfluoroalkoxy resin for use as electrical insulation.

Note 1

This standard is similar but not identical to IEC 60684-3-240 to -243.

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.
