【国外标准】 Standard Specification for Polytetrafluoroethylene-Backed Pressure-Sensitive Electrical Insulating Tape

This specification establishes the manufacture of and requirements for two types and two grades of electrical insulating tape consisting of a polytetrafluoroethylene (PTFE) film coated on one side with a pressure-sensitive adhesive. Type I is standard backing, while Type II is bondable backing tape. Grades are designate based on backing thickness. Besides standard lengths, widths, and thicknesses, tapes shall also conform to other requirements such as breaking strength, elongation, adhesion to steel and backing, dielectric breakdown, and high-humidity insulation resistance.1.1 This specification covers electrical insulating tape consisting of a polytetrafluoroethylene (PTFE) 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 parentheses are for information only.NOTE 1: This standard is similar to IEC 60454-3-14.1.3 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.
