(Specification)Standard Specification for Steel Wire for Masonry Joint Reinforcement
Standard Specification for Steel Wire for Masonry Joint Reinforcement
ABSTRACT
Specification covers masonry joint reinforcements fabricated from cold-drawn steel wires. It specifies that joint reinforcement consists of longitudinal wires welded to cross wires. Wire used in the manufacture of masonry joint reinforcement shall be round. Masonry joint reinforcement shall then be assembled by automatic machines or by other suitable mechanical means that will assure accurate spacing and alignment of all members of the finished product. Longitudinal and cross wires shall be securely connected at every intersection by an electric-resistance welding process and then it shall be deformed. Tension, weld shear strength, and bend tests shall be performed on the samples. When corrosion protection of joint reinforcement has been provided, it shall be either zinc coated mill or hot-dip galvanized.
SCOPE
1.1 This specification covers masonry joint reinforcement fabricated from cold-drawn steel wire. Joint reinforcement consists of longitudinal wires welded to cross wires.
1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. 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 document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
