ASTM D2969
1. 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 1For other methods of testing tire cords and tire cord fabrics, refer to Methods D 885, Test Methods D 1871, Specifications D 122, and Test Methods D 2692 and D 2970. For tolerances on tire cords and tire cord fabrics, refer to Specifications D 122 and Methods D 885.
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:
| Subject | Section |
| Adhesion of Steel Cords and Filaments to Elastomers | |
| Brass Coating Composition and Mass | , |
| Breaking Force (Strength) | |
| Construction | |
| Data Form for Reporting Test Results | |
| Elongation at Break | |
| Elongation Between Defined Forces (EDF) | |
| Flare | |
| Lay | |
| Linear Density | |
| Visual Appearance | |
| Nomenclature System | |
| Residual Torsions | |
| Straightness | |
| Thickness and Out-of-Roundness |
1.5 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 and Note 0.
1.4 This standard is written in SI units. No other units of measurement are included in this standard.
