Designation:D35013Standard Test Methods forFlexible Treated Sleeving Used for Electrical Insulation1This standard is issued under the fixed designation D350;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 electri-cal insulating sleeving comprising a flexible tubular productmade from a woven textile fibre base,such as cotton,rayon,nylon,or glass,thereafter impregnated,or coated,or impreg-nated and coated,with a suitable dielectric material.1.2 The procedures appear in the following sections:ProceduresSectionsBrittleness Temperature18 to 21Compatibility of Sleeving with Magnet Wire Insulation45 to 59Conditioning6Dielectric Breakdown Voltage12 to 17Dielectric Breakdown Voltage After Short-Time Aging29 to 33Dimensions7 to 11Effect of Push-Back After Heat Aging73 to 78Flammability22 to 28Hydrolytic Stability66 to 72Oil Resistance34 to 37Selection of Test Material5Solvent Resistance60 to 65Thermal Endurance38 to 441.3 The values stated in inch-pound units,except for C,areto be regarded as the standard.The values in parentheses aremathematical conversions to SI units that are provided forinformation only and are not considered standard.1.4 This is a fire-test-response standard.See Sections 22through 28,which are the procedures for flammability tests.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 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 specific hazardstatements,see 45.2 and 63.1.1.NOTE1This standard resembles IEC 60684-2,Specification forFlexible Insulating SleevingPart 2 Methods of Test,in a number ofways,but is not consistently similar throughout.The data obtained usingeither standard are not necessarily technically equivalent.1.7 Fire testing is inherently hazardous.Adequate safe-guards for personnel and property shall be employed inconducting these tests.2.Referenced Documents2.1 ASTM Standards:2D149 Test Method for Dielectric Breakdown Voltage andDielectric Strength of Solid Electrical Insulating Materialsat Commercial Power FrequenciesD374 Test Methods for Thickness of Solid Electrical Insu-lation(Withdrawn 2013)3D471 Test Method for Rubber PropertyEffect of LiquidsD746 Test Method for Brittleness Temperature of Plasticsand Elastomers by ImpactD876 Test Methods for Nonrigid Vinyl Chloride PolymerTubing Used for Electrical InsulationD1711 Terminology Relating to Electrical InsulationD2307 Test Method for Thermal Endurance of Film-Insulated Round Magnet WireD3487 Specification for Mineral Insulating Oil Used inElectrical ApparatusD3636 Practice for Sampling and Judging Quality of SolidElectrical Insulating MaterialsD5423 Specification for Forced-Convection Laboratory Ov-ens for Evaluation of Electrical InsulationD6054 Practice for Conditioning Electrical Insulating Mate-rials for Testing(Withdrawn 2012)3E145 Specification for Gravity-Convection and Forced-Ventilation OvensE176 Terminology of Fire Standards1These test methods are under the jurisdiction of ASTM Committee D09 onElectrical and Electronic Insulating Materials and are the direct responsibility ofSubcommittee D09.07 on Flexible and Rigid Insulating Materials.Current edition approved Nov.1,2013.Published December 2013.Originallyapproved in 1932.Last previous edition approved in 2009 as D350 09.DOI:10.1520/D0350-13.2For 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 2.2 IEEE Standard:IEEE 101 Guide for the StatisticalAnalysis of Thermal LifeTest Data42.3 IEC Standard:IEC 60684-2SpecificationforFlexibleInsulatingSleevingPart 2 Methods of Test52.4 ISO Standard:ISO 13943 Fire SafetyVocabulary3.Terminology3.1 Definitions:3.1.1 Use Terminology E176 and ISO 13943 for definitionsof terms used in this test method and associated with fireissues.Where difference
