ASTM A884/A884M-14

Standard Specification for Epoxy-Coated Steel Wire and Welded Wire Reinforcement

ABSTRACT
This specification covers plain and deformed steel wire and plain and deformed steel welded wire reinforcement with protective epoxy coating for use in concrete, masonry and mechanically stabilized earth applications. The materials under this specification shall be in accordance with other ASTM documents enlisted herein. Tests for coating thickness and continuity shall be made on each size of wire or style of welded wire reinforcement. Bend tests for coating flexibility shall be conducted on at least one wire of each size or style or welded wire reinforcement. If the specimen fails to meet the specified requirements for coating thickness, continuity, or bend test (if applicable), two retests on random specimens shall be conducted for each failed test. If both retests meet the specified requirements, the coated material represented by the specimens shall be accepted.
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 1—The 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. TABLE 1 Best Test Requirements
