(Test Method)Standard Test Methods for Friction Tapes
Standard Test Methods for Friction Tapes
SIGNIFICANCE AND USE
In most applications, a friction tape must have adequate adhesion to remain in place and function properly.
SCOPE
1.1 These test methods cover the methods and procedures for testing friction tapes. Such tapes consist of a woven fabric sheeting that has been impregnated with an adhesive insulating compound and cut into rolls of narrow width. These tapes are commonly used for protecting and binding in place, insulation applied to joints of electrical wires and cables, and for other mechanical purposes.
Note 1—The material specifications formerly included in these test methods are now contained in Specification D4514.
1.2 The test methods included in this standard are as follows:
Sections Adhesion 6-11 Aged Adhesion 12-17 Breaking Strength 18-23 Dielectric Breakdown Voltage 24-29 Dimensions 30-35 Discoloration of Copper 36-40 Parallelism 41-45
1.3 The values stated in inch-pound units are the standard. The SI units in parentheses are for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Note 2—There is no equivalent IEC standard.
