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, Polyamide films, Polyimide films, and Combinations thereof. 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 46 – 53 Bond Strength After Solvent Immersion 110 – 115 Breaking Strength and Elongation at Room Temperature 37 – 45 Breaking Strength and Elongation at Low Temperatures 37 – 45 Conditioning 6 – 8 Curling and Twisting 140 – 146 Dielectric Breakdown Voltage 83 – 90 Effect of Accelerated Aging on High-Temperature Tapes 97 – 103 Flagging 66 – 76 Flammability 104 – 109 Hazards/Precautions 3 Insulation Resistance at High Humidity 91 – 96 Length of Tape in a Roll 28 – 36 Oil Resistance 116 – 122 Puncture Resistance 123 – 128 Resistance to Accelerated Aging (Heat and Moisture) 129 – 139 Sampling 4 Specimen Preparation 5 Thermosetting Properties 77 – 82 Thickness 21 – 27 Unwind Force at Room Temperature 54 – 65 Unwind Force at Low Temperatures 54 – 65 Width 11 – 20 Note 1: These procedures apply to both Class 1 and Class 2 tapes except as noted above. 1.4 These test methods are used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but do not by themselves incorporate all factors required for fire hazard or fire risk assessment of the materials, products or assemblies under actual fire conditions. 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 and IEC 60454–3-All Sheets address the same subject matter, but differ in technical content. 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, health, and environmental 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.
