This specification covers woven wire plaster base, flat or self-furring, with or without stiffener wires, and with or without backing, designed for use as a base to receive gypsum or Portland cement based plaster. Backing shall allow lapping of wire-to-wire and backing-to-backing of one mesh at ends and edges and shall have a minimum tensile breaking strength. The wire shall be zinc-coated (galvanized). The weight, size, and diameter of the wire are specified.

1.1 This specification covers woven wire plaster base, flat or self-furring, with or without stiffener wires, and with or without factory-attached water-resistive barrier, designed for use as a base to receive gypsum or portland cement based plaster.

1.2 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 non-conformance with the standard. Within the text, the SI units are shown in brackets.

1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
