ASTM D2969-02

Standard Test Methods for Steel Tire Cords

SCOPE
1.1 These test methods cover the testing of cords made from steel that are specifically designed for use in the reinforcement of pneumatic tires. By agreement, these test methods may be used to test similar cords or filaments used for reinforcing other rubber products. The steel cords may be wound on spools or beams. The steel cords may also be woven into fabric, in which case they must be removed from the fabric prior to testing.
Note 1—For other methods of testing tire cords and tire cord fabrics, refer to Methods D885, Test Methods D1871, Specifications D122, and Test Methods D2692 and D2970. For tolerances on tire cords and tire cord fabrics, refer to Specifications D122 and Methods D885.
1.2 These test methods include test procedures only; they do not establish specifications or tolerances.
1.3 This test method includes the following sections:SubjectSectionAdhesion of Steel Cords and Filaments to Elastomers16Brass Coating Composition and Mass14, 15 Breaking Force (Strength)10Construction12Data Form for Reporting Test ResultsAppendix X1Elongation at Break10Elongation Between Defined Forces (EDF)11Flare8Lay12Linear Density9Visual Appearance8Nomenclature SystemAnnex A1Residual Torsions8Straightness8Thickness and Out-of-Roundness13
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. See 14.3 and Note 11.
1.4 This standard is written in SI units. No other units of measurement are included in this standard.
