ASTM D 1676:2024

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, rectangular or square, copper or aluminum film-insulated magnet wire. 1.3 The values stated in inch-pound units are 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 - 12 Burnout (AC Overload Resistance) 13 - 21 Chemical Resistance 22 - 28 Coefficient of Friction 29 - 37 Continuity, DC High Voltage 38 - 45 Continuity, DC Low Voltage 46 - 53 Completeness of Cure 54 - 60 Cut-Through Temperature (Thermoplastic Flow) 61 - 68 Dielectric Breakdown AC Voltage 69 - 75 Dielectric Breakdown AC Voltage after Bending 76 - 82 Dielectric Breakdown AC Voltage at Elevated Temperatures 83 - 89 Dielectric Breakdown AC Voltage after Conditioning in Refrigerant Atmosphere 90 - 99 Dimensional Measurement 100 - 106 Dissipation Factor Measurement 107 - 114 Electrical Resistance 115 - 121 Elongation 122 - 129 Extractables, Refrigerant 130 - 140 Film Adherence and Flexibility 141 - 148 Formability: a) Elastic Ratio 152 b) Low Stress Elongation 153 c) Spring Back 154 - 155 Heat Shock 156 - 162 Oiliness 163 - 169 Scrape Resistance, Unidirectional 170 - 177 Solderability ...
