【国外标准】 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,  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 – 53Adhesion Strength to Steel and Backing at Low Temperatures 46 – 53Bond Strength After Solvent Immersion 110 – 115Breaking Strength and Elongation at Room Temperature 37 – 45Breaking Strength and Elongation at Low Temperatures 37 – 45Conditioning 6 – 8Curling and Twisting 140 – 146Dielectric Breakdown Voltage 83 – 90Effect of Accelerated Aging on High-Temperature Tapes 97 – 103Flagging 66 – 76Flammability 104 – 109Hazards/Precautions 3Insulation Resistance at High Humidity 91 – 96Length of Tape in a Roll 28 – 36Oil Resistance 116 – 122Puncture Resistance 123 – 128Resistance to Accelerated Aging (Heat and Moisture) 129 – 139Sampling 4Specimen Preparation 5Thermosetting Properties 77 – 82Thickness 21 – 27Unwind Force at Room Temperature 54 – 65Unwind Force at Low Temperatures 54 – 65Width 11 – 20NOTE 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.
