    1. Scope

    1.1 This specification covers plain and deformed steel wire and plain and deformed steel welded wire reinforcement with protective epoxy coating. A Class A minimum coating thickness is required for wire and welded wire reinforcement intended for use in concrete and masonry. A Class B minimum coating thickness is required for wire and welded wire reinforcement intended for use in mechanically stabilized earth applications. A Type 1 coating is a fusion-bonded epoxy coating that has been formulated to be sufficiently flexible to allow bending of the coated wire or welded wire reinforcement. A Type 2 coating is a fusion-bonded epoxy coating that has not been designed to be sufficiently flexible to allow bending of the coated wire or welded wire reinforcement.

    Note 1The coating applicator is identified throughout this specification as the manufacturer.

    1.2 This specification is applicable for orders in either inch-pound units (as Specification A884) or SI units (as Specification A884M).

    1.3 The values stated in either inch-pound 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 except as specifically noted in Table 1. Combining values from the two systems may result in non-conformance with this specification.

It is the responsibility of the user of this specification to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
