【国外标准】 Standard Specification for Steel Wire, Deformed, for Concrete Reinforcement (Withdrawn 2013)

This specification covers deformed steel wires that have been cold-worked by drawing, rolling, or both drawing and rolling, to be used as produced, or in fabricated form, for the reinforcement of concretes. Deformations shall be spaced along the wire at a substantially uniform distance and its average spacing and height shall be determined. Tension tests shall be used to determine the required tensile properties such as tensile strength and yield strength. Bend test shall be performed to determine if the specimen shall withstand being bent at room temperature through right angle without cracking on the outside of the bent portion.1.1 This specification covers deformed steel wire which has been cold-worked by drawing, rolling, or both drawing and rolling, to be used as produced, or in fabricated form, for the reinforcement of concrete in sizes having nominal cross-sectional areas not less than 6.45 mm 2 [0.01 in.2].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 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 1).
