ASTM D 1871 : 1998

1.1 These test methods cover procedures for testing the strength of adhesion of single-filament wire to vulcanized rubber compounds. The methods apply to, but are 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 or the force generated by strip peeling.

1.2 These test methods are applicable to single-filament wires used in reinforced rubber products as single filaments and are normally used to evaluate the adhesion of samples of wire to a standard rubber applied under specified conditions. They are primarily used to evaluate tire bead wire or hose reinforcing 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 These test methods are written in SI units. The inch-pound units which are provided in these methods are not necessarily exact equivalents of the SI units. Either system of units may be used in these methods. In case of referee decisions the SI units will prevail.

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.
