Designation:D167617Standard Test Methods forFilm-Insulated Magnet Wire1This standard is issued under the fixed designation D1676;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 These test methods cover procedures for testing film-insulated magnet wire that is used in electrical apparatus.Thesetest methods are intended primarily for the evaluation of theelectrical insulating materials used.The intent is that these testmethods be used,except where modified,by individual speci-fications for particular applications.1.2 These test methods present different procedures forevaluating 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:SectionsBond Strength4 12Burnout(AC Overload Resistance)13 21Chemical Resistance22 28Coefficient of Friction29 37Continuity,DC High Voltage38 45Continuity,DC Low Voltage46 53Completeness of Cure54 60Cut-Through Temperature(Thermoplastic Flow)61 68Dielectric Breakdown AC Voltage69 75Dielectric Breakdown AC Voltage after Bending76 82Dielectric Breakdown AC Voltage at Elevated Temperatures83 89Dielectric Breakdown AC Voltage after Conditioning in Refriger-ant Atmosphere90 99Dimensional Measurement100 106Dissipation Factor Measurement107 114Electrical Resistance115 121Elongation122 129Extractables,Refrigerant130 140Film Adherence and Flexibility141 148Formability:a)Elastic Ratio152b)Low Stress Elongation153c)Spring Back154-155Heat Shock156 162Oiliness163 169Scrape Resistance,Unidirectional170 177Solderability178 185Resistance to Insulating Liquids and Hydrolytic Stability186 1951.5 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.Specific hazard statements are given in 9.5,19.1,19.3,19.8,52.1,58,59.1,74.1,112.1,135.4,and 182.3.NOTE1This test method is related to IEC 60851.Since both methodscontain multiple test procedures,many procedures are technically equiva-lent while others differ significantly.1.6 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:A228/A228M Specification for Steel Wire,Music SpringQualityB3 Specification for Soft or Annealed Copper WireB43 Specification for Seamless Red Brass Pipe,StandardSizesB193 Test Method for Resistivity of Electrical ConductorMaterialsB279 Test Method for Stiffness of Bare Soft Square andRectangular Copper andAluminum Wire for Magnet WireFabricationB324 Specification for Aluminum Rectangular and SquareWire for Electrical PurposesB609/B609M Specification for Aluminum 1350 RoundWire,Annealed and Intermediate Tempers,for ElectricalPurposesD149 Test Method for Dielectric Breakdown Voltage andDielectric Strength of Solid Electrical Insulating Materialsat Commercial Power FrequenciesD150 Test Methods for AC Loss Characteristics and Permit-tivity(Dielectric Constant)of Solid Electrical InsulationD374/D374M Test Methods for Thickness of Solid Electri-cal InsulationD877 Test Method for Dielectric Breakdown Voltage ofInsulating Liquids Using Disk ElectrodesD1533 Test Method for Water in Insulating Liquids by1These test methods are under the jurisdiction of ASTM Committee D09 onElectrical and Electronic Insulating Materials and are the direct responsibility ofSubcommittee D09.12 on Electrical Tests.Current edition approved Nov.1,2017.Published December 2017.Originallyapproved in 1959.Last previous edition approved in 2011 as D1676 03(2011).DOI:10.1520/D1676-17.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 Coulometric Karl Fischer TitrationD1711 Terminology Relating to Electrical InsulationD2475 Specification for FeltD2519 Test Method for Bond Strength of Electrical Insulat-ing Varnishes by the Helical Coil TestD5423
