Designation:D61914An American National StandardStandard Test Methods forVulcanized Fibre Used for Electrical Insulation1This standard is issued under the fixed designation D619;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 the procedures for testingvulcanized fibre sheets,tubes,and rods of such grades as canbe used for electrical insulation.1.2 The procedures appear in the following sections:ProcedureSectionArc resistance23Ash6Bond strength(ply adhesion)16Bursting strength14Compressive strength12,25,30Conditioning4Density17,26,32Dielectric strength18,27Dimensional measurements28,33Flammability22Flexural strength13,31Silica7Tearing strength11Tensile strength10,24,29Thickness(sheets)20Resistance to impact15Rockwell hardness19Volatile matter8Water absorption5Zinc chloride91.3 The values stated in inch-pound units are to be regardedas the standard.The SI values given in parentheses are forinformation only.1.4 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.Specific hazardstatements are given in 7.3,22.1,22.2.NOTE1The test methods described herein are similar technically tothose described in IEC Publication 60667-2.Not all of the tests in thisdocument are included in IEC 60667-2,and the procedures in the twopublications are not completely identical;but it is expected that compa-rable results will be obtained from most of the procedures.Conductcomparative tests if necessary before directly comparing results of testsusing the different procedures.2.Referenced Documents2.1 ASTM Standards:2D149 Test Method for Dielectric Breakdown Voltage andDielectric Strength of Solid Electrical Insulating Materialsat Commercial Power FrequenciesD202 Test Methods for Sampling and Testing UntreatedPaper Used for Electrical InsulationD229 Test Methods for Rigid Sheet and Plate MaterialsUsed for Electrical InsulationD256 Test Methods for Determining the Izod PendulumImpact Resistance of PlasticsD348 Test Methods for Rigid Tubes Used for ElectricalInsulationD349 Test Methods for Laminated Round Rods Used forElectrical InsulationD374 Test Methods for Thickness of Solid Electrical Insu-lation(Withdrawn 2013)3D495 Test Method for High-Voltage,Low-Current,Dry ArcResistance of Solid Electrical InsulationD570 Test Method for Water Absorption of PlasticsD668 Test Methods of Measuring Dimensions of Rigid Rodsand Tubes Used for Electrical InsulationD689 Test Method for Internal Tearing Resistance of Paper(Withdrawn 2009)3D695 Test Method for Compressive Properties of RigidPlasticsD710 Specification for Vulcanized Fibre Sheets,Rods,andTubes Used for Electrical InsulationD785 Test Method for Rockwell Hardness of Plastics andElectrical Insulating MaterialsD792 Test Methods for Density and Specific Gravity(Rela-tive Density)of Plastics by DisplacementD828 Test Method for Tensile Properties of Paper andPaperboard Using Constant-Rate-of-ElongationApparatus(Withdrawn 2009)31These 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 MaterialsCurrent edition approved Nov.1,2014.Published December 2014.Originallyapproved in 1941.Last previous edition approved in 2004 as D619 99(2004)which was withdrawn January 2013 and reinstated in November 2014.DOI:10.1520/D0619-14.2For 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 D952 Test Method for Bond or Cohesive Strength of SheetPlastics and Electrical Insulating MaterialsD1711 Terminology Relating to Electrical InsulationD6054 Practice for Conditioning Electrical Insulating Mate-rials for Testing(Withdrawn 2012)32.2 IEC Standard:IEC 60667-2 Specification for Vulcanized Fibre for Electri-cal PurposesPart 2:Methods of Test43.Terminology3.1 DefinitionsFor definitions of terms used in this stan-dard refer to Terminology D1711.3.2 Definitions of Terms Specific to This Standard:3.2.1 In referring to the cutting of specimens and theapplication of the load,the following definitions of termsapply.These definitions of terms correspond to
