Designation:D87613Standard Test Methods forNonrigid Vinyl Chloride Polymer Tubing Used for ElectricalInsulation1This standard is issued under the fixed designation D876;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 the testing of general-purpose(Grade A),low-temperature(Grade B),and high-temperature(Grade C)2nonrigid vinyl chloride polymer tubing,or itscopolymers with other materials,for use as electrical insula-tion.For the purpose of these test methods nonrigid tubingshall be tubing having an initial elongation in excess of 100%at break.NOTE1These test methods are similar but not identical to those inIEC 606842.1.2 The values stated in inch-pound units are to be regardedas standard,except for temperature,which shall be expressedin degrees Celsius.The values given in parentheses aremathematical conversions to SI units that are provided forinformation only and are not considered standard.1.3 The procedures appear in the following sections:ProcedureSectionASTM ReferenceStandardBrittleness Temperature43 45D746Corrosion Tests74 85D1000Dielectric Breakdown Voltage at High Humidity65 73E104Dielectric Breakdown Voltage58 64D149Dimensional Tests8 14D374Effect of Elevated Temperatures25 36D412Flammability Test15 21Oil Resistance Test35 42D471Penetration Test46 51Sampling6Strain Relief Test68 73Tension Test22 24D412Test Conditions7Volume Resistivity52 57D2571.4 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.For specific hazardstatements,see Section 5.1.5 For fire test caveats,see Section 15.2.Referenced Documents2.1 ASTM Standards:3D149 Test Method for Dielectric Breakdown Voltage andDielectric Strength of Solid Electrical Insulating Materialsat Commercial Power FrequenciesD257 Test Methods for DC Resistance or Conductance ofInsulating MaterialsD374 Test Methods for Thickness of Solid Electrical Insu-lation(Withdrawn 2013)4D412 Test Methods for Vulcanized Rubber and Thermoplas-tic ElastomersTensionD471 Test Method for Rubber PropertyEffect of LiquidsD746 Test Method for Brittleness Temperature of Plasticsand Elastomers by ImpactD1000 Test Methods for Pressure-Sensitive Adhesive-Coated Tapes Used for Electrical and Electronic Applica-tionsD1711 Terminology Relating to Electrical InsulationD5032 Practice for Maintaining Constant Relative Humidityby Means of Aqueous Glycerin SolutionsE104 Practice for Maintaining Constant Relative Humidityby Means of Aqueous SolutionsE176 Terminology of Fire Standards2.2IEC Standards:606842 Flexible insulating sleeving,Part 2,Methods oftest53.Terminology3.1 Definitions:1These 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 1946.Last previous edition approved in 2009 as D876 09.DOI:10.1520/D0876-13.2Test methods applicable to Grade B will be specified at a later date.3For 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.4The last approved version of this historical standard is referenced onwww.astm.org.5Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.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 3.1.1 For definitions pertaining to electrical insulation,referto Terminology D1711.3.1.2 For definitions pertaining to fire standards,refer toTerminology E176.3.2 Definitions of Terms Specific to This Standard:3.2.1 brittleness temperature,nthat temperature at which50%of the specimens fail when the specified number aretested,using the apparatus and conditions specified.3.2.2 corrosive effect,nunder the prescribed conditions,the percentage change in electrical resistance of a fine copperwire in contact with the tubing.3.2.3 resistance to penetration,nthat property of tubingindicated by its resistance to high local pressures,as deter-mined by the temperature at which a steel ball punctures thetubing under the conditions of loading and temperature risespecified in these test methods.3.2.4 wall th
