Short description
1. Scope 1.1 These test methods cover procedures for testing film-insulated magnet wire that is used in electrical apparatus. These test methods are intended primarily for the evaluation of the electrical insulating materials used. The intent is that these test methods be used, except where modified, by individual specifications for particular applications. 1.2 These test methods present different procedures for evaluating given properties of round and shaped, copper and aluminum film-insulated magnet wire. 1.3 The values stated in inch-pound units are to be regarded as the standard. The SI units in parentheses are provided for information only. 1.4 The test methods appear in the following sections: Sections Bond Strength 4 to 12 Burnout 13 to 21 Chemical Resistance 22 to 28 Coefficient of Fraction 29 to 37 Continuity, High Voltage 38 to 45 Continuity, Low Voltage 46 to 53 Completeness of Cure 54 to 60 Cut-Through Temperature 61 to 68 Dielectric Breakdown Voltage 69 to 75 Dielectric Breakdown Voltage after Bending 76 to 82 Dielectric Breakdown Voltage at Elevated Temperatures 83 to 89 Dielectric Breakdown Voltage after Conditioning in Refrigerant Atmosphere 90 to 99 Dimensional Measurement 100 to 106 Dissipation Factor Measurement 107 to 114 Electrical Resistance 115 to 121 Elongation 122 to 129 Extractables, Refrigerant 130 to 140 Film Adherence and Flexibility 141 to 148 Formability: a) Elastic Ratio 152 b) Low Stress Elongation 153 c) Spring Back 154 to 155 Heat Shock 156 to 162 Oiliness 163 to 169 Scrape Resistance, Unidirectional 170 to 177 Solderability 178 to 185 Resistance to Insulating Liquids 186 to 195 1.5 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. Specific hazard statements are given in Notes 1, 2, 4, 6, 7, 11, 13, 16, 20, 21, 27, 28 and 10.1.
