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 1

Welded 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" (WWR) 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 specification and in 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. (Within the text the inch-pound units are shown in brackets.)
