Designation:D885/D885M10a(Reapproved 2014)1Standard Test Methods forTire Cords,Tire Cord Fabrics,and Industrial Filament YarnsMade from Manufactured Organic-Base Fibers1This standard is issued under the fixed designation D885/D885M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1NOTEEq 27 was corrected editorially in October 2014.1.Scope1.1 These test methods cover the testing of industrialfilament yarns made wholly of manufactured organic-basefibers,cords twisted from such yarns,fabrics woven from suchcords,and products that are made specifically for use in themanufacture of pneumatic tires.They may be applied to similaryarns and cords used for reinforcing other rubber goods and forother industrial applications.The test methods apply to nylon,polyester,and rayon yarns and tire cords twisted from suchyarns and to fabrics made from such cords.The yarn or cordmay be wound on cones,tubes,bobbins,spools,or beams;maybe woven into fabric;or may be in some other form.Themethods include testing procedure only and include no speci-fications or tolerances.1.2 No procedure is included for the determination offatigue resistance of cord,but several commonly used proce-dures for the measurement of fatigue resistance of cords inrubber were published in the appendix of these test methods inthe 1967 Annual Book of ASTM Standards,Part 24,and inearlier issues of Test Methods D885.1.3 The sections on“Growth of Conditioned Yarns andCords,”“Properties of Yarns and Cords at ElevatedTemperature,”and“Properties of Wet Yarns and Cords”havebeen moved to Appendix X1 Appendix X3 as non-mandatoryinformational items because of their very limited use by theindustry and because precision and bias statements are notincluded.1.4 This standard includes the following sections:SectionAdhesion of Cord to Elastomers34Bibliography of Tire Cord Test MethodsX5Breaking Strength(Force)of Yarns and Cords at Elevated Tempera-tureX2.3Breaking Strength(Force)of Conditioned Yarns and Cords16Breaking Strength(Force)of Oven-Dried Rayon Yarns and Cords23Breaking Strength(Force)of Rayon Yarns and Cords at SpecifiedMoisture Regain Level,Adjustment of17Breaking Tenacity of Conditioned Yarns and Cords18Breaking Tenacity of Oven-Dried Rayon Yarns and Cords24Breaking Toughness of Yarns and Cords28Commercial Mass9Conditioning7Contraction of Wet Yarns and CordsX3Count of Tire Cord Fabric37Dip(Adhesive)Solids Pickup on Yarns and Cords33Elongation at Break of Conditioned Yarns and Cords19Elongation at Break of Oven-Dried Rayon Yarns and Cords25Elongation of Rayon Yarns and Cords at a Specified Moisture RegainLevel,Adjustment of Observed20Extractable Matter in Yarns and Cords32Force at Specified Elongation(FASE)of Conditioned Yarns andCords21Force at Specified Elongation(FASE)of Oven-Dried Rayon Yarns andCords26Growth of Conditioned Yarns and CordsX1Identification of Fibers8Keywords40Linear Density11Mass of per Unit Area of Tire Cord Fabric36Modulus of Conditioned Yarns and Cords22Moisture Regain,Actual10Precision and Bias of Certain Yarn and Cord Tests3935 toProperties of Tire Cord Fabric38Sampling6Shrinkage Force of Conditioned Yarns and Cords at Elevated Temper-atureX2.5Shrinkage of Conditioned Yarns and Cords at Elevated TemperatureX2.4Significance and Use,General5Significance and Use,Tensile Properties14SI Calculations(examples for work-to-break,specific work-to-break,and breaking toughness)X4Stiffness of Fabric3812 toTensile Properties of Yarns and Cords28Terminology3Thickness of Cords31Twist in Yarns and Cords30Width of Tire Cord Fabric35Work-to-Break of Yarns and Cords271.5 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated in1These test methods are under the jurisdiction of ASTM Committee D13 onTextiles and are the direct responsibility of Subcommittee D13.19 on IndustrialFibers and Metallic Reinforcements.Current edition approved May 15,2014.Published June 2014.Originallyapproved in 1946.Last previous edition approved in 2010 as D885/D885M 10a.DOI:10.1520/D0885_D0885M-10AR14E01.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 each system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.6 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
