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).

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.)

This specification covers steel-welded wire reinforcements, deformed for concrete reinforcement. The welded wire reinforcement shall be furnished either in flat sheets, or in rolls as specified by the purchaser. The wires shall be assembled, connected to every intersections, and shall be fabricated and finished wherein the wires shall conform to the required specifications. Tensile, bend and weld shear strength tests shall be performed to assure the specimens meet the mechanical property requirements.1.1 This specification covers welded wire reinforcement made from cold-worked drawn or rolled deformed wire, or a combination of deformed and non-deformed wires, to be used for the reinforcement of concrete.Note 1Welded wire for concrete reinforcement has been described by various terms: welded wire fabric, WWF, fabric, and mesh. The wire reinforcement industry prefers the term "welded wire reinforcement" (WWF) as being more representative of the range of products being manufactured. Therefore, the term "welded wire fabric" has been replaced with the term "welded wire reinforcement" in this specifcation and in other related specifications.1.2 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.

This specification covers steel welded wire reinforcements to be used for the reinforcement of concrete. The wires shall be assembled by automatic machines or by other suitable mechanical means that shall assure accurate spacing and alignment of all wires of the finished welded wire reinforcement. Test specimens shall be obtained by cutting from the finished welded wire reinforcement a full width section of sufficient length to perform testing. The wire shall withstand mechanical tests such as tensile test and bend test and shall meet the minimum requirements on reduction of area and wear shear strength. The welded wire reinforcement shall be acceptable if the average of all test values across the specimen meets each of the prescribed minimum values.1.1 This specification covers welded wire reinforcement to be used for the reinforcement of concrete.Note 1Welded wire for concrete reinforcement has been described by various terms: welded wire fabric, WWF, fabric, and mesh.
