Standard Test Method for Pressure-Sensitive Adhesive-Coated Tapes Used for Electrical and Electronic Applications
SCOPE
1.1 These test methods cover procedures for testing pressure-sensitive adhesive-coated tapes to be used as electrical insulation and are classified as follows:
1.1.1 Class 1 -Non-elastomeric backings made from materials such as: Paper, flat or creped, Fabric, uncoated or coated, Cellulose ester films, Polyethylene terephthalate (polyester) films, Fluorocarbon polymer films, Composite filament films, Polyamide films, Polyimide films, and Combinations thereof.
1.1.2 Class 2 -Elastomeric backings that are characterized by both high stretch and substantial recovery made from materials such as: Vinyl chloride and co-polymers, Vinylidene chloride and co-polymers, and Polyethylene and co-polymers. Note 1-Laminates of Class 1 and Class 2 backings should be tested according to Class 1 test methods.
1.2 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. For specific hazards see Section 3.
1.3 The procedures appear in the sections indicated: Paper, flat or creped, Fabric, uncoated or coated, Cellulose ester films, Polyethylene terephthalate (polyester) films, Fluorocarbon polymer films, Composite filament films, Polyamide films, Polyimide films, and Combinations thereof.
1.4 The values stated in inch-pound units are the standard, unless otherwise noted. If a value for measurement is followed by a value in SI units in parentheses, the second value may only be approximate. The first stated value is the requirement.
