ASTM D1871 : 04(2010)

Standard Test Method for Adhesion Between Tire Bead Wire and Rubber

Standard Details

1.1 This test method cover procedures for testing the strength of adhesion of single-filament wire to vulcanized rubber compounds. The method applies to, but is not limited to, wire made from brass, bronze, or zinc coated steel wire. The adhesion strength is expressed as the magnitude of the pull-out force for the single filament of wire.

1.2 This test method is applicable to single-filament wires used in reinforced rubber products as single filaments and is normally used to evaluate the adhesion of samples of wire to a standard rubber applied under specified conditions. It is primarily used to evaluate tire bead wire and may be applied, with modifications and by agreement between supplier and customer, to various wire types used in rubber product reinforcing.

1.3 This test method is written in SI units.

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 6.5.1.
