Standard Specification for Steel Wire, Plain, for Concrete Reinforcement AASHTO Designation: M 32M/M 32-09 ASTM Designation: A 82/A 82M-07 1. SCOPE 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 either 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 nonconformance with the standard. (The inch-pound units are shown in brackets except in Table 6.) 2. REFERENCED DOCUMENTS 2.1.
