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

1.1.1 Class 1—Non-elastomeric backings made from materials such as:

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

1.2 Laminates of Class 1 and Class 2 backings should be tested according to Class 1 test methods.

1.3 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.

1.4 The procedures appear in the sections indicated below and in alphabetical order:

Note 1—These procedures apply to both Class 1 and Class 2 tapes except as noted above.

1.5 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, the second value may only be approximate and 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.

1.6 This is a fire–test response standard.
