This specification covers as cold-drawn or galvanized steel wires to be used as such, or in fabricated form, for the reinforcement of concrete. The steel shall be made by one of the following processes: open-hearth, electric furnace, or basic-oxygen. The wires shall be cold drawn from rods that have been hot rolled from billets. The tests described include tension, bending, and reduction of area tests. After undergoing tension test, the tensile and yield strength properties of the test specimen shall conform to the requirements of a reference material based on nominal area of the wire. The specimen for bend test shall withstand being bent at room temperature without cracking on the outside of the bent portion. The reduction of area shall be determined as described in a reference document.

1.1 This specification covers cold-drawn steel wire, as-drawn or galvanized, to be used as such, or in fabricated form, for the reinforcement of concrete, in sizes not less than 2.03 mm [0.080 in.] nominal diameter.

1.2 Supplement S1 describes high-strength wire, which shall be furnished when specifically ordered. It shall be permissible to furnish high-strength wire in place of regular wire if mutually agreed to by the purchaser and the manufacturer.

1.3 The values stated in SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard (The inch-pound units are shown in brackets except in Table 6.)
