ASTM A82 / A82M

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.
