【国外标准】 Standard Specification for Polyester Film Pressure-Sensitive Electrical Insulating Tape (Withdrawn 2020)

This specification covers the manufacture, testing, and standard requirements of four types of electrical insulating tape consisting of a polyester plastic film coated on one side with a pressure-sensitive adhesive. Besides differences in nominal thickness, Type 1 is a general-purpose tape coated with a thermoplastic adhesive that is not chemically heat reactive, while Types 2, 3, and 4 are general-purpose tapes coated with a heat-reactive thermosetting adhesive. The tapes shall be tested accordingly and consequently conform to standard widths, lengths, and thicknesses, and other specific properties such as elongation, penetraction, high-humidity insulation resistance (measure of corrosion), strain relief (shrinkage), breaking strength, dielectric breakdown, and adhesion to steel and backing.1.1 This specification covers electrical insulating tape consisting of a polyester plastic film coated on one side with a pressure-sensitive adhesive.1.2 The values stated in SI units are to be regarded as the standard. The values given in parenthesis are provided for information only.Note 1—This standard and IEC 60454–3–2 and –3 are similar but not equivalent in all details.
