Scope

1.1 This specification covers deformed and plain steel reinforcing bars which prior to surface preparation are prefabricated and then coated with a protective fusion-bonded epoxy coating by electrostatic spray or other suitable method. 1.2 Prefabricated steel reinforcing bars coated with fusionbonded epoxy powder coating in accordance with this specification are intended to be fabricated before being coated. 1.3 Organic coatings other than epoxy may be used provided they meet the requirements of this specification. 1.4 Requirements for epoxy coatings are contained in Annex A1. 1.5 Requirements for patching material are contained in Annex A2 in Specification A775/A775M. 1.6 Guidelines for application process and product test procedures of epoxy coatings for steel reinforcing bars are presented in Appendix X1. 1.7 Guidelines for construction practices at the job-site for coated steel reinforcing bars are presented in Appendix X2. 1.8 This specification is applicable for orders in either inch-pound units (as Specification A934) or SI [metric] units [as Specification A934M]. 1.9 The values stated in either inch-pound units or SI 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. 1.10 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.11 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.
