Designation:D263313aStandard Test Methods forThermoplastic Insulations and Jackets for Wire and Cable1This standard is issued under the fixed designation D2633;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 procedures for the testing ofthermoplastic insulations and jackets used on insulated wireand cable.To determine the test to be made on the particularinsulation or jacket compound,refer to the product specifica-tion for that type.These test methods do not apply to the classof products known as flexible cords.The electrical tests oninsulation and water-absorption tests do not apply to the classof products having a separator between the conductor and theinsulation.1.2 These test methods pertain to insulation or jacketmaterial for electrical wires and cables.In many instances theinsulation or jacket material cannot be tested unless it has beenformed around a conductor or cable.Therefore,tests are doneon insulated or jacketed wire or cable in these test methodssolely to determine the relevant property of the insulation orjacket material and not to test the conductor or completedcable.1.3 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.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.For specific hazardssee Sections 4 and 63.1.5 The procedures appear in the following sections:ProcedureSectionsCold Bend Test75 to 77Dielectric Strength Retention Test45 to 51Electrical Tests of Insulation17 to 29Heat Distortion Test74Heat Shock Test73Insulation Resistance Test30 to 37Partial-Discharge Extinction Level Test38 to 44Physical Tests of Insulation and Jackets5 to 16Surface Resistivity Test64 to 67Thermal Tests72 to 77Track Resistance Test78 to 81U-Bend Discharge Test68 to 71Vertical Flame Test63Water Absorption Tests,Accelerated52 to 622.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 InsulationD257 Test Methods for DC Resistance or Conductance ofInsulating MaterialsD374 Test Methods for Thickness of Solid Electrical Insu-lation(Withdrawn 2013)3D471 Test Method for Rubber PropertyEffect of LiquidsD573 Test Method for RubberDeterioration in an AirOvenD638 Test Method for Tensile Properties of PlasticsD1711 Terminology Relating to Electrical InsulationD1248 Specification for Polyethylene Plastics ExtrusionMaterials for Wire and CableD2132 Test Method for Dust-and-Fog Tracking and ErosionResistance of Electrical Insulating MaterialsD3755 Test Method for Dielectric Breakdown Voltage andDielectric Strength of Solid Electrical Insulating MaterialsUnder Direct-Voltage StressD5025 Specification for Laboratory Burner Used for Small-Scale Burning Tests on Plastic MaterialsD5207 Practice for Confirmation of 20mm(50W)and125mm(500W)Test Flames for Small-Scale BurningTests on Plastic MaterialsD5423 Specification for Forced-Convection Laboratory Ov-ens for Evaluation of Electrical InsulationE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with Specifications1These methods are under the jurisdiction of ASTM Committee D09 onElectrical and Electronic Insulating Materials and are the direct responsibility ofSubcommittee D09.18 on Solid Insulations,Non-Metallic Shieldings and Coveringsfor Electrical and Telecommunication Wires and Cables.Current edition approved Nov.1,2013.Published December 2013.Originallyapproved in 1967.Last previous edition approved in 2013 as D2633 13.DOI:10.1520/D2633-13a.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 2.2 Federal Standard:Federal Specification for Tape;Paper,Gummed(Kraft)(PPP-T-45D)42.3 ICEA Standard:T-24-380 Guide for Partial-Discharge Procedure52.4 UL Standard:UL 2556 Wire and Cable Test Methods63.Terminology3.1 Definitions:For definitions of terms used in these testmethods,refer to
