ASTM A933/A933M-95 - 1.1.2001
 
1. Scope

1.1 This specification covers plain and deformed steel wire and plain and deformed steel welded wire fabric with protective vinyl (PVC, polyvinyl chloride, or polyvinyl chloride powder compound) coating. Class A is intended for use as reinforcement in concrete and Class B as reinforcement in earth.

1.2 Other thermoplastic organic coatings may be used provided they meet the requirements of this specification.

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

1.3 Requirements for coatings are contained in Annex A1.

1.4 This specification is applicable for orders in either inch-pound units (as Specification A933) or in SI units [as Specification A933M].

1.5 The values stated in either inch-pound or SI units are to be regarded as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification.
