Designation:D473113Standard Specification forHot-Application Filling Compounds for TelecommunicationsWire and Cable1This standard is issued under the fixed designation D4731;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 variety of petroleum-basedand other compounds used for filling the air spaces in telecom-munications wires and cables(both electrical and fiber optic)for the purpose of preventing water and other undesirable fluidsfrom entering or migrating through the cable structure.(Forrelated standards see Specifications D4730 and D4732).1.2 A hot-application compound is a material that requiresmelting in order to be applied as a liquid and its melting pointaffects its performance in the finished cable product.1.3 The values stated in SI units are to be regarded asstandard.The values given in parentheses are mathematicalconversions to inch-pound units that are provided for informa-tion only and are not considered standard.2.Referenced Documents2.1 ASTM Standards:2D6 Test Method for Loss on Heating of Oil and AsphalticCompoundsD92 Test Method for Flash and Fire Points by ClevelandOpen Cup TesterD97 Test Method for Pour Point of Petroleum ProductsD127 Test Method for Drop Melting Point of PetroleumWax,Including PetrolatumD150 Test Methods for AC Loss Characteristics and Permit-tivity(Dielectric Constant)of Solid Electrical InsulationD257 Test Methods for DC Resistance or Conductance ofInsulating MaterialsD445 Test Method for Kinematic Viscosity of Transparentand Opaque Liquids(and Calculation of Dynamic Viscos-ity)D938 Test Method for Congealing Point of PetroleumWaxes,Including PetrolatumD1500 Test Method for ASTM Color of Petroleum Products(ASTM Color Scale)D2161 Practice for Conversion of Kinematic Viscosity toSaybolt Universal Viscosity or to Saybolt Furol ViscosityD3895 Test Method for Oxidative-Induction Time of Poly-olefins by Differential Scanning CalorimetryD3954 Test Method for Dropping Point of WaxesD4565 Test Methods for Physical and Environmental Per-formance Properties of Insulations and Jackets for Tele-communications Wire and CableD4568 Test Methods for Evaluating Compatibility BetweenCable Filling and Flooding Compounds And PolyolefinWire and Cable MaterialsD4730 Specification for Flooding Compounds for Telecom-munications Wire and CableD4732 Specification for Cool-Application Filling Com-pounds for Telecommunications Wire and CableD4872 Test Method for Dielectric Testing of Wire and CableFilling Compounds3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 filling materialany of several materials used to fillthe air spaces in the cores of multi-conductor insulated wiresand cables,or between buffer tubes covering optical fibers,orwithin such buffer tubes,or any combination of these configu-rations and any other cable components,for the purpose ofexcluding water and other undesirable fluids;especially withregard to telecommunications wire and cable,including opticalcable,intended for outside aerial,buried,or undergroundinstallations.3.1.2 producerthe primary manufacturer of the material.3.1.3 suppliersjobbers and distributors as distinct fromproducers.4.Classification4.1 Two basic types of filling compounds are covered,asfollows:4.1.1 Type IGeneral-purpose filling compounds includeall materials to be used for filling cables that are not required1This 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.Subcommittee D02.10contributed in the development of this standard.Current edition approved May 1,2013.Published July 2013.Originally approvedin 1987.Last previous edition approved in 2008 as D473102(2008)1.DOI:10.1520/D4731-13.2For 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 to function under electrical stress(for example,all dielectricfiber-optic cable),including filling compounds for fiber-opticloose buffer tubes.4.1.2 Type IIElectrical-type filling compounds includematerials having prescribed electrical properties and used forfilling wires and cables that are required to function fully orpartially under electrical stress(including hybrid fiber-opticcable).5.Ordering Information5.1 Orders for material under this speci
