Designation:D647722Standard Terminology Relating toTire Cord,Bead Wire,Hose Reinforcing Wire,and Fabrics1This standard is issued under the fixed designation D6477;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 terminology is the compilation of all definitionsdeveloped by Subcommittee D13.19 on Tire Cords and Fab-rics.1.2 The terminology,mostly definitions,is unique to the tirecord fabric industry.Meanings of the same terms used outsidethe tire cord fabric industry can be found in other compilationsor in dictionaries of general usage.1.3 In addition to being a specialized dictionary,this termi-nology is also a tool for managing the Subcommitteesterminology.This includes finding,eliminating,and preventingredundancies,that is,where two or more terms relating to thesame concept are defined in different words.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D123 Terminology Relating to TextilesD885/D885M Test Methods for Tire Cords,Tire CordFabrics,and Industrial Filament Yarns Made from Manu-factured Organic-Base FibersD1871 Test Method for Adhesion Between Tire Bead Wireand RubberD2229 Test Method for Adhesion Between Steel Tire Cordsand RubberD2692/D2692M Test Method for Air Permeability of TireFabrics,Tire Cord Fabrics,Tire Cord,and YarnsD2969 Test Methods for Steel Tire CordsD2970/D2970M Test Methods for Testing Tire Cords,TireCord Fabrics,and Industrial Yarns Made From GlassFilamentsD4776/D4776M Test Method for Adhesion of Tire Cordsand Other Reinforcing Cords to Rubber Compounds byH-Test ProcedureD4974/D4974M Test Method for Hot Air Thermal Shrink-age of Yarn and Cord Using a Thermal Shrinkage OvenD4975 Test Methods for Single-Filament Tire Bead WireMade from SteelD5591 Test Method for Thermal Shrinkage Force of Yarnand Cord With a Thermal Shrinkage Force TesterD6320/D6320M Test Methods for Single Filament HoseReinforcing Wire Made from SteelD6477 Terminology Relating to Tire Cord,Bead Wire,HoseReinforcing Wire,and Fabrics(Withdrawn 2022)3D6611 Test Method for Wet and Dry Yarn-on-YarnAbrasionResistanceD7269/D7269M Test Methods for Tensile Testing ofAramidYarnsD7812 Test Method for Tensile Testing of Aramid PaperD8054/D8054M Test Methods for Tensile Testing of Para-Aramid Flat Yarns3.Terminologyabrasion,nthe wearing away of any part of a material byrubbing against another surface.D6611adhesion,nin tire fabrics,the force required to separate atextile material from rubber or other elastomer by a definiteprescribed method.D1871,D2229,D4776/D4776Madhesion,nthe property denoting the ability of a material toresist delamination or separation into two or more layers.D6477adhesive treated tire cord,na tire cord whose adhesion torubber or other elastomer has been improved by the appli-cation of a dip followed by rapid drying and(normally)additional heat treatment.D5591air wicking,n in tires,the passage of air longitudinally alongor through yarns in a fabric that has been encased and cured1This terminology is under the jurisdiction ofASTM Committee D13 on Textilesand is the direct responsibility of Subcommittee D13.19 on Industrial Fibers andMetallic Reinforcements.Current edition approved June 1,2022.Published July 2022.Originally approvedin 1999.Last previous edition approved in 2013 as D6477131which waswithdrawn January 2022 and reinstated in June 2022.DOI:10.1520/D6477-22.2For 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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1in rubber or other elastomer,that is,air permeability in theplane of the fabric.D2692/D2692Mapex angle,nthe angle formed between the incoming andoutgoing yarn at the top(and bottom)of the inter-wrappedyarn area in the static condition.DISCUSSIONIn yarn abrasion testing,the state of a yarn,which hasbeen soaked for a prescribed period of time in water befor
