Designation:D303210Standard 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 The test procedures and their locations are as follows:SectionAxial Stability(Longitudinal Change)After Thermal Exposure21Bondability of Insulation to Potting Compounds19Capacitance9 to 12Cold Bend Test26Concentricity16Crush Resistance20Dielectric Breakdown Voltage5Dimensions15Dry-Arc Tracking29Dynamic Cut-Through22Fluid Immersion23High Temperature Shock24Insulation-Continuity Proof Tests13Insulation Resistance6Partial Discharge(Corona)Inception and Extinction Voltage25Relative Thermal Life and Temperature Index14Strip Force27Surface Resistance7Tensile Properties17Vertical Flame Test18Voltage Rating of Hook-Up WireA2Voltage Withstand Test8Wet Arc-Tracking281.4 The values stated in SI units are to be regarded asstandard.The values given in parentheses are mathematicalconversions to inch-pound units that are provided for informa-tion only and are not considered standard.1.5 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 and health practices and determine the applica-bility of regulatory limitations prior to use.For specificprecaution statements,see 12.2.1,12.4.1.8,18.1.3,Note 17,and 25.4.2.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(Withdrawn 2013)3D412 Test Methods for Vulcanized Rubber and Thermoplas-tic ElastomersTensionD471 Test Method for Rubber PropertyEffect of LiquidsD543 Practices for Evaluating the Resistance of Plastics toChemical ReagentsD638 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,Inclined-Plane Tracking and Erosion of Insulating MaterialsD2307 Test Method for Thermal Endurance of Film-Insulated Round Magnet WireD2865 Practice for Calibration of Standards and Equipmentfor Electrical Insulating Materials TestingD3183 Practice for RubberPreparation of Pieces for Test1These test methods are under the jurisdiction of ASTM Committee D09 onElectrical and Electronic Insulating Materials and are the direct responsibility ofSubcommittee D09.18 on Solid Insulations,Non-Metallic Shieldings and Coveringsfor Electrical and Telecommunication Wires and Cables.Current edition approved March 1,2010.Published April 2010.Originallyapproved in 1972.Last previous edition approved in 2004 as D303204.DOI:10.1520/D3032-10.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.*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 States1 Purposes from ProductsD3636 Practice for Sampling and Judging Quality of SolidElectrical Insulating MaterialsD3638 Test Method for Comparative Tracking Index ofElectrical Insulating MaterialsD5032 Practice for Maintaining Constant Relative Humidityby Means of Aqueous Glycerin SolutionsD5374 Test Methods for Forced-Convection Laboratory Ov-ens for Evaluation of Electrical InsulationD5423 Specification for Forced-Convection Laboratory Ov-ens for Evaluation of Electrical InsulationD6054 Practice for Conditioning Electrical Insulating Mate-rials for Testing(Withdrawn 2012)3E29 Practice for Using Significant Digits in Test Data toDetermine Confor
