Designation:D303221aStandard Test Methods forHookup Wire Insulation1This standard is issued under the fixed designation D3032;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 These test methods cover procedures for testing hookupwire.1.2 For the purposes of these test methods,hookup wireinsulation includes all components of the insulation systemused on single insulated conductors or an assembly of singleinsulated conductors such as a cable bundle and harness or flatribbon cable.The insulating materials include not only theprimary insulation over the conductor,but also insulatingjackets over shielded constructions.1.3 These test methods and their locations are as follows:SectionAxial Stability(Longitudinal Change)After Thermal Exposure20Bondability of Insulation to Potting Compounds18Capacitance9 to 11Cold Bend Test25Concentricity25Crush Resistance19Dielectric Breakdown Voltage5Dimensions14Dry-arc Tracking28Dynamic Cut-through21Fluid Immersion22High Temperature Shock23Insulation-Continuity Proof Tests12Insulation Resistance6Partial Discharge(Corona)Inception and Extinction Voltage24Relative Thermal Life and Temperature Index13Strip Force26Surface Resistance26Tensile Properties16Vertical Flame17Vertical Flame Test A18.5(Test MethodD8354)Vertical Flame Test B17.6 17.11.4Voltage Rating of Hook-Up WireAnnex A1Voltage Withstand Test8Wet Arc-tracking271.4 The values stated in SI units are to be regarded asstandard.The values given in parentheses after SI units areprovided for information only and are not considered standard.1.5 This standard measures and describes the response ofmaterials,products,or assemblies to heat and flame undercontrolled conditions,but does not,by itself,incorporate allfactors required for fire hazard or fire risk assessment of thematerials,products,or assemblies under actual fire conditions.1.6 Fire testing is inherently hazardous.Adequate safe-guards for personnel and property shall be employed inconducting these tests.1.7 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.For specific warning statements,see 17.1.3,24.4,and Note 18.1.8 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:2D149 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 InsulationD257 Test Methods for DC Resistance or Conductance ofInsulating MaterialsD374 Test Methods for Thickness of Solid Electrical Insu-lation(Metric)D0374_D0374MD412 Test Methods for Vulcanized Rubber and Thermoplas-tic ElastomersTensionD471 Test Method for Rubber PropertyEffect of LiquidsD543 Practices for Evaluating the Resistance of Plastics toChemical Reagents1These test methods are under the jurisdiction of ASTM Committee D09 onElectrical and Electronic Insulating Materials and are the direct responsibility ofSubcommittee D09.07 on Electrical Insulating Materials.Current edition approved April 1,2021.Published June 2021.Originallyapproved in 1972.Last previous edition approved in 2021 as D3032 21.DOI:10.1520/D3032-21A.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.*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.1D638 Test Method for Tensile Properties of PlasticsD1711 Terminology Relating to Electrical InsulationD1868 Test Method for Detection and Measurement ofPartial Discharge(Corona)Pulses in Evaluation of Insu-lation SystemsD2303 Test Methods for Liquid-Contaminant
