Designation:D456614Standard Test Methods forElectrical Performance Properties of Insulations andJackets for Telecommunications Wire and Cable1This standard is issued under the fixed designation D4566;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 electricaltesting of thermoplastic insulations and jackets used on tele-communications wire and cable and for the testing of electricalcharacteristics of completed products.To determine the proce-dure to be used on the particular insulation or jacketcompound,or on the end product,reference should be made tothe specification for the product.1.2 The test methods appear in the following sections of thisstandard:Test MethodSectionsElectrical Tests of InsulationIn-Process4 8DC proof test8Insulation defect or fault rate7Spark test6Electrical Tests of Completed Wire and Cable9 51Attenuation24Attenuation,effects due to aging31Attenuation,effects due to elevated temperature29Attenuation,effects due to humidity30Attenuation to crosstalk ratiofar end(ACR-F)28Attenuation to crosstalk rationear end(ACR-N)26Capacitance deviation19Capacitance difference20Capacitance unbalance,Pair-to-ground(CUPG)22Capacitance unbalance,Pair-to-pair(CUPP)21Capacitance unbalance,Pair-to-support wire23Characteristic ImpedanceMethod 1 Propagation con-stantand capacitance47Characteristic ImpedanceMethod 2,Single-endedmeasurements48Characteristic ImpedanceMethod 3 Least SquaresFunction Fit49Coaxial capacitance(capacitance to water)17Conductor continuity11Conductor resistance(CR)13Conductor resistance unbalance(CRU of pairs)15Continuity of other metallic elements12Crosses test(continuity between wires of different pairs)35Crosstalk loss,far-end27Crosstalk loss,near-end25Test MethodSectionsDC proof test,Core-to-internal shield(screen)40DC proof test,Core-to-shield38DC proof test,Core-to-support wire39DC proof test,Internal shield(screen)-to-shield41DC proof test,Other required isolations42DC proof test,Wire-to-wire37Fault rate test(air core only)33Insulation resistance(IR)32Jacket voltage breakdown rating test36Mutual capacitance(CM)18Mutual conductance16Phase Constant44Phase Delay45Phase Velocity46Resistance of other metallic cable elements14Shorts test(continuity between wires of a pair)34Structural Return Loss and Return Loss50Unbalance attenuation(conversion losses)51Voltage surge test431.3 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.1.4 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.Specific hazardstatements are given in Sections 6 and 37.2.Referenced Documents2.1 ASTM Standards:2B193 Test Method for Resistivity of Electrical ConductorMaterialsD150 Test Methods for AC Loss Characteristics and Permit-tivity(Dielectric Constant)of Solid Electrical InsulationD1711 Terminology Relating to Electrical InsulationD2633 Test Methods for Thermoplastic Insulations andJackets for Wire and CableD3426 Test Method for Dielectric Breakdown Voltage andDielectric Strength of Solid Electrical Insulating Materials1These test 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 May 15,2014.Published May 2014.Originallyapproved in 1986.Last previous edition approved in 2008 as D4566 081.DOI:10.1520/D4566-14.2For 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.*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 Using Impulse WavesD5423 Specification for Forced-Convection Laboratory Ov-ens for Evaluation of Electrical InsulationE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with Specifications2.2 ANSI Standard:ANSI/IEEE Standard 100 IEEE Standard Dictionary ofElectrical and Electronics Terms32.3 IEC Standard:IEC 61156-1 Multicore and Symmetrical Pair/Quad Cablesfor Digital CommunicationsPart 1:Generic Specifica-tion33.Terminology3.1 DefinitionsFor definitions of terms us
