Standard Test Methods for Pressure-Sensitive Adhesive-Coated Tapes Used for Electrical and Electronic Applications
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:
Paper, flat or creped,
Fabric, uncoated or coated,
Cellulose ester films,
Polyethylene terephthalate (polyester) films,
Fluorocarbon polymer films,
Composite filament films,
Polyimide films, and
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:
Vinyl chloride and co-polymers,
Vinylidene chloride and co-polymers, and
Polyethylene and co-polymers.
1.2 Test laminates of Class 1 and Class 2 backings according to Class 1 test methods.
1.3 The procedures appear in the sections indicated below and in alphabetical order:
Adhesion Strength to Steel and Backing at Room Temperature
46 – 53
Adhesion Strength to Steel and Backing at Low Temperatures
Bond Strength After Solvent Immersion
110 – 115
Breaking Strength and Elongation at Room Temperature
37 – 45
Breaking Strength and Elongation at Low Temperatures
6 – 8
Curling and Twisting
140 – 146
Dielectric Breakdown Voltage
83 – 90
Effect of Accelerated Aging on High-Temperature Tapes
97 – 103
66 – 76
104 – 109
Insulation Resistance at High Humidity
91 – 96
Length of Tape in a Roll
28 – 36
116 – 122
123 – 128
Resistance to Accelerated Aging (Heat and Moisture)
129 – 139
77 – 82
21 – 27
Unwind Force at Room Temperature
54 – 65
Unwind Force at Low Temperatures
11 – 20
Note 1: These procedures apply to both Class 1 and Class 2 tapes except as noted above.
1.4 This is a fire-test response standard (see Section 104).
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, 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.
1.6 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.
1.7 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.
