ASTM International Standard Specification for Nonmetallic Semi-Conducting and Electrically Insulating Rubber Tapes ASTM D4388-20

This specification covers nonmetallic semi-conducting and electrically insulating rubber tapes designed for the splicing and repair of electrical wire and cables operating at specified phase to phase voltages. The tapes, which are classified into five types (Types I, II, III, IV, and V), shall conform to physical property requirements such as tensile strength, elongation at break, dielectric strength, dissipation factor, permittivity, volume resistivity, behavior during fusion test, ozone resistance, heat exposure, and UV resistance.
