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 Units—The values stated in SI units are the standard. The inch-pound units in parentheses are for information only. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. NOTE 2—There is no equivalent IEC standard. 1.5 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.
