This specification covers the properties and requirements for electrical insulating tape consisting of a backing of vinyl chloride plastic, coated on one side with a pressure-sensitive adhesive, for use at low temperatures. Four types are included providing two thicknesses at two operating temperatures. Selected from standard widths and lengths, the tapes shall conform to specified values of the following requirements: break strength; break and static elongation; dielectric breakdown; adhesion to both steel and backing; roll unwind; high-humidity insulation resistance; flammability; and behavior during flagging test.

1.1 This specification covers an electrical insulating tape for use at low temperature down to approximately -18°C (0°F). The tape consists of a backing of vinyl chloride plastic, coated on one side with a pressure-sensitive adhesive. Four types are included providing two thicknesses at two operating temperatures.

1.2 The values stated in SI units are the standard. The values given in parentheses are provided for information purposes only.
