Designation:D355407(Reapproved 2013)Standard Specification forTrack-Resistant Black Thermoplastic High-DensityPolyethylene Insulation for Wire and Cable,75 COperation1This standard is issued under the fixed designation D3554;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.Scope1.1 This specification covers track-resistant black thermo-plastic high-density polyethylene insulation.Before applica-tion to the conductor,the insulation shall comply with therequirements of Specification D1248,Type III,Class C,Category 5,Grade E10,J4,or J5.The requirements ofSpecification D1248 shall not apply to the insulation removedfrom the conductor.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.1.3 This insulation is suitable for use on wire or in cableused for power transmission in overhead spaced-line service,installed at temperatures above 25 C and exposed to sunlightand other atmospheric environments between 55 and+75 C.1.4 In many instances,the insulation cannot be tested unlessit has been formed around a conductor.Therefore,tests done oninsulated wire in this standard are solely to determine therelevant property of the insulation and not to test the conductoror completed cable.1.5 Whenever two sets of values are presented,in differentunits,the values in the first set are the standard,while those inparentheses are for information only.2.Referenced Documents2.1 ASTM Standards:2D1248 Specification for Polyethylene Plastics ExtrusionMaterials for Wire and CableD1693 Test Method for Environmental Stress-Cracking ofEthylene PlasticsD1711 Terminology Relating to Electrical InsulationD1928 Practice for Preparation of Compression-MoldedPolyethylene Test Sheets and Test Specimens(Withdrawn2001)3D2132 Test Method for Dust-and-Fog Tracking and ErosionResistance of Electrical Insulating MaterialsD2633 Test Methods for Thermoplastic Insulations andJackets for Wire and Cable3.Terminology3.1 Definitions:3.1.1 For definitions of terms used in this specification,referto Terminology D1711.3.2 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.Physical Properties4.1 When tested for physical and aging requirements,heatdistortion,cold bend,U-bend discharge,and surface resistivityin accordance with Test Methods D2633,environmental crack-ing in accordance with Test Method D1693,and track resis-tance in accordance with Test Method D2132,the track-resistant black thermoplastic high-density polyethyleneinsulation shall meet the requirements specified in Table 1.5.Electrical Requirements5.1 Subject cable specimens to a 5 min ac or dc voltagewithstand test at voltages which are based on the nominalthickness of the insulation.Conduct tests in accordance withTest Methods D2633 using 125 V/mil(5 kV/mm)for ac testsor 375 V/mil(15 kv/mm)for dc tests.6.Sampling6.1 Sample the insulation in accordance with Test MethodsD2633 and Test Method D1693.1This specification is under the jurisdiction of ASTM Committee D09 onElectrical and Electronic Insulating Materials and is the direct responsibility ofSubcommittee D09.18 on Solid Insulations,Non-Metallic Shieldings and Coveringsfor Electrical and Telecommunication Wires and Cables.Current edition approved March 1,2013.Published March 2013.Originallyapproved in 1977.Last previous edition approved in 2007 as D3554 07.DOI:10.1520/D3554-07R13.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 7.Test Methods7.1 Test the insulation in accordance with Test MethodsD2633 and Test Method D1693,modified as noted in Table 1,and noted as follows.7.2 To test for environmental cracking in accordance withTest Method D1693,test specimens shall be molded inaccordance with Procedure C of Practice D1928 and the testreagent shall be 10%Igepal CO-630.47.3 Test the track resistance in accordance with Test MethodD2132.8.Keywords8.1 ac test;cold bend;dc test;elongation;environmentalcracking;heat distortion;high-density polyethylene;surfaceresistivity;tensile strength;thermoplastic;track-resistant;u-bend dischargeASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentionedin this standard.Users of this standard are expressly advised that determination of the validity of any
