ASTM D2754-99(2004)

Standard Specification for High-Temperature Glass Cloth Pressure-Sensitive Electrical Insulating Tape

ABSTRACT
This specification covers the requirements for two types of high-temperature electrical insulating tape consisting of glass cloth coated on one side with a pressure-sensitive adhesive. Type I, which is subdivided into two grades (Grade A and B) according to thickness, is woven glass cloth with silicone adhesive. Type II, on the other hand, is woven glass cloth impregnated with polytetrafluoroethylene, silicone adhesive. Tapes shall undergo tests that shall examine their conformance to the following requirements: standard thickness, width, and length; breaking strength; dielectric breakdown; adhesion strength both to steel and backing; high-humidity insulation resistance; unwind force; and accelerated aging.
SCOPE
1.1 This specification covers requirements for high-temperature electrical insulating tape consisting of glass cloth 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 provided for information purposes only.
