ASTM D2686 Standard Specification for Polytetrafluoroethylene-Backed Pressure-Sensitive Electrical Insulating Tape
ASTM D2686 聚四氟乙烯为基底对压力敏感的电绝缘胶带用标准规范

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.
