Designation:D22913Standard Test Methods forRigid Sheet and Plate Materials Used for ElectricalInsulation1This standard is issued under the fixed designation D229;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 rigidelectrical insulation normally manufactured in flat sheet orplate form.They are generally used as terminal boards,spacers,voltage barriers,and circuit boards.1.2 Use Test Methods D619(withdrawn)or SpecificationD710 for tests applying to vulcanized fibre.1.3 Some of the test methods contained in this standard aresimilar to those contained in IEC 60893-2,which applies torigid industrial laminated sheets based on thermosetting resinsfor electrical purposes.1.4 The test methods appear in the following sections:TestSectionsASTMTestMethodAcetone extractable matter83 to 84D494Arc resistance47D495Ash56 to 60.Bonding strength49 to 54.Burning rate and flame resistance61 to 75.Compressive strength25D695Conditioning4D6054Dissipation factor34 to 40D669Dielectric strength28 to 33D149Expansion(linear thermal)76D696Flexural properties12 to 24D790Hardness(Rockwell)55D785Insulation resistance and resistivity41 to 46D257Permittivity34 to 40D150Resistance to impact26D256Tensile properties7 to 11D638Thickness5 to 6D374Tracking resistance48D2132Warp or twist77 to 82.Water absorption27D5701.5 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.6 This is a fire-test-response standard.See Sections 61through 75,which are the procedures for burning rate andflame resistance.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 and health practices and determine the applica-bility of regulatory limitations prior to use.Specific precau-tionary statements are given in 31.1 and 1.8.1.8 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.1.9 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 FrequenciesD150 Test Methods for AC Loss Characteristics and Permit-tivity(Dielectric Constant)of Solid Electrical InsulationD256 Test Methods for Determining the Izod PendulumImpact Resistance of PlasticsD257 Test Methods for DC Resistance or Conductance ofInsulating MaterialsD374 Test Methods for Thickness of Solid Electrical Insu-lation(Withdrawn 2013)3D494 Test Method for Acetone Extraction of PhenolicMolded or Laminated ProductsD495 Test Method for High-Voltage,Low-Current,Dry Arc1These 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 November 2013.Originallyapproved in 1925.Last previous edition approved in 2009 as D229 09b.DOI:10.1520/D0229-13.2For 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 Resistance of Solid Electrical InsulationD570 Test Method for Water Absorption of PlasticsD617 Test Method for Punching Quality of Phenolic Lami-nated Sheets(Withdrawn 2003)3D619 Test Methods for Vulcanized Fibre Used for ElectricalInsulationD638 Test Method for Tensile Properties of PlasticsD669 Test Method for Dissipation Factor and PermittivityParallel with Laminations of Laminated Sheet and PlateMaterials(Withdrawn 2012)3D695 Test Method for Compressive Properties of RigidPlasticsD696 Test Method for Coefficient of Linear Thermal Expan-sion of Plastics Between 30C and 30C with a VitreousSilica DilatometerD710 Specification for Vulcanized Fibre Sheets
