Designation:D135120Standard Specification forThermoplastic Polyethylene Insulation for Electrical Wireand Cable1This standard is issued under the fixed designation D1351;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 This specification covers a thermoplastic insulationwhich consists substantially of polyethylene.1.2 This type of insulation is considered suitable for use onwire or cable that will be used for continuous operation atconductor temperatures up to 75 C with a maximum conduc-tor size of 1000 kcmil(507 mm2).The maximum voltage ratingshall not exceed 35 000 V for power application or 9 000 V forseries lighting.1.3 In many instances the insulation material cannot betested unless it has been formed around a conductor.Therefore,tests done on insulated wire or cable in this specification aresolely to determine the relevant property of the insulationmaterial and not to test the insulated conductor or completedcable.1.4 Whenever two sets of values are stated,in differentunits,the values in the first set are regarded as standard,whilethe values in parentheses are provided for information only andare not considered standard.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D1248 Specification for Polyethylene Plastics ExtrusionMaterials for Wire and CableD1711 Terminology Relating to Electrical InsulationD2308 Specification for Thermoplastic Polyethylene Jacketfor Electrical Wire and CableD2633 Test Methods for Thermoplastic Insulations andJackets for Wire and CableD3349 Test Method for Absorption Coefficient of EthylenePolymer Material Pigmented with Carbon Black2.2 ICEA Standard:3T-24-380 Guide for Partial-Discharge Procedure3.Terminology3.1 Definitions:3.1.1 Refer to Terminology D1711 for definitions of termsused in this specification.3.2 Definitions of Terms Specific to This Standard:3.2.1 aging(act of),nexposure of materials to air at atemperature of 100 C for 48 h.4.High Voltage Hazard4.1 High Voltage:4.1.1 Lethal voltages are a potential hazard during theperformance of this test.It is essential that the test apparatus,and all associated equipment electrically connected to it,beproperly designed and installed for safe operation.4.1.2 Solidly ground all electrically conductive parts whichit is possible for a person to contact during the test.4.1.3 Provide means for use at the completion of any test toground any parts which were at high voltage during the test orhave the potential for acquiring an induced charge during thetest or retaining a charge even after disconnection of thevoltage source.4.1.4 Thoroughly instruct all operators as to the correctprocedures for performing tests safely.4.1.5 When making high voltage tests,particularly in com-pressed gas or in oil,it is possible for the energy released atbreakdown to be sufficient to result in fire,explosion,orrupture of the test chamber.Design test equipment,testchambers,and test specimens so as to minimize the possibilityof such occurrences and to eliminate the possibility of personalinjury.If the potential for fire exists,have fire suppression1This specification is under the jurisdiction of ASTM Committee D09 onElectrical and Electronic Insulating Materials and is the direct responsibility ofSubcommittee D09.07 on Electrical Insulating Materials.Current edition approved Oct.1,2020.Published October 2020.Originallyapproved in 1954.Last previous edition approved in 2014 as D1351 14.DOI:10.1520/D1351-20.2For 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.3Available from The Insulated Cable Engineers Association,Inc.(ICEA),P.O.Box 2694,Alpharetta,GA 30023,http:/.*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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1equipment available.Design test equipment,test chambers,and test specimens so as to minimize the possibility of suchoccurrences and to eliminate the possibility of personal injur
