Designation:D456813Standard Test Methods forEvaluating Compatibility Between Cable Filling andFlooding Compounds And Polyolefin Wire and CableMaterials1This standard is issued under the fixed designation D4568;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 evaluate the compatibility betweencable filling or cable flooding compounds,or both,andpolyolefin materials used in the manufacture of wire and cablethat are usually in intimate contact with the filler or floodant,orboth.1.2 These test methods are useful to ensure compatibilityand to verify that new formulations of filling or floodingcompounds will have no deleterious effect upon the otherpolyolefin materials being used or,conversely,use thesemethods to ensure that other polyolefin wire and cable mate-rials are evaluated for possible use not degraded by contactwith fillers or floodants already in use.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.2.Referenced Documents2.1 ASTM Standards:2D1711 Terminology Relating to Electrical InsulationD1928 Practice for Preparation of Compression-MoldedPolyethylene Test Sheets and Test Specimens(Withdrawn2001)3D2633 Test Methods for Thermoplastic Insulations andJackets for Wire and CableD4730 Specification for Flooding Compounds for Telecom-munications Wire and CableD4731 Specification for Hot-Application Filling Com-pounds for Telecommunications Wire and CableD4732 Specification for Cool-Application Filling Com-pounds for Telecommunications Wire and CableD5423 Specification for Forced-Convection Laboratory Ov-ens for Evaluation of Electrical Insulation3.Terminology3.1 Definitions:3.1.1 For definitions of terms used in these test methods,refer to Terminology D17113.2 Definitions of Terms Specific to This Standard:3.2.1 aging(act of),nexposure of materials to filling orflooding compound at a specified temperature for a specifiedtime.3.2.2 filling compoundany of several materials(see Speci-fications D4731 and D4732)used to fill the air spaces in thecores of multi-conductor insulated wires and cables for thepurpose of excluding air or moisture or both;especially withregard to telecommunications wire and cable intended fordirect burial.3.2.3 flooding compoundany of several materials(seeSpecification D4730)used to flood wire or cable sheathinterfaces(for example,the region between core wrap and ashield,between a shield and a jacket,etc.)to eliminate or tominimize normal voids or air spaces in these areas;especiallywith regard to telecommunications wire and cable intended fordirect burial.1These 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.Members of ASTMCommittee D02 on Petroleum Products and Lubricants and ASTM Committee B07on Light Metals and Alloys have contributed to these test methods.Current edition approved Nov.1,2013.Published December 2013.Originallyapproved in 1986.Last previous edition approved in 2009 as D4568 99(2009).DOI:10.1520/D4568-13.2For 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.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 4.Significance and Use4.1 Cable filling and flooding compounds are normallysemi-solid at room temperature and fluid in varying degrees atelevated temperatures.They are normally applied in a liquidstate and at an elevated temperature during wire and cablemanufacturing.The completed finished wire or cable is ex-posed to various ambient conditions during its useful life.If notcarefully selected,components of filling or flooding com-pounds have the potential to degrade the materials they contact,short term or long term.The following methods are intended tominimize the chances of such problems occurring.4.2 Some of the effects that might occur include,but are notlimited to:4.2.1 Delamination of coated metal sh
