scope:

These test methods cover procedures for testing pressure-sensitive adhesive-coated tapes to be used as electrical insulation. These tapes are classified as follows

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

Class 2-Elastomeric backings that are characterized by both high stretch and substantial recovery. These backings are made from materials such as

Vinyl chloride and co-polymers,

Vinylidene chloride and co-polymers, and

Polyethylene and co-polymers

Test laminates of Class 1 and Class 2 backings according to Class 1 test methods

NOTE 1-These procedures apply to both Class 1 and Class 2 tapes except as noted above

This is a fire-test response standard (see Section 104)

The values stated in SI units are the standard, unless otherwise noted. If a value for measurement is followed by a value in inch-pound or English units in parentheses, it is likely that the second value will only be approximate and it is for information only. The first stated value is the preferred unit

NOTE 2-These test methods are similar to IEC 60454-3, but may differ sometimes in some details

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

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
