Historical Standard: ASTM D4975-96a Standard Test Methods for Single-Filament Tire Bead Wire Made from Steel
SUPERSEDED (see Active link, below)
ASTM D4975
1. Scope
1.1 These test methods cover testing of single-filament steel wires that are components of tire beads used in the manufacture of pneumatic tires. By agreement, these test methods may be applied to similar filaments used for reinforcing other rubber products.
1.2 These test methods describe test procedures only and do not establish specifications and tolerances.
1.3 These test methods are written in SI units. The inch-pound units which are provided are not necessarily exact equivalents of the SI units. Either system of units may be used in these test methods. In case of referee decisions the SI units will prevail.
1.4 These test methods cover the determination of the mechanical properties listed below:
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.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
