ASTM A775/A775M-19

Standard Specification for Epoxy-Coated Steel Reinforcing Bars

ABSTRACT
This specification covers deformed and plain steel reinforcing bars with protective epoxy coating applied by the electrostatic spray method. The surface of the steel reinforcing bars to be coated shall be cleaned by abrasive blast cleaning to near-white metal. The number and frequency of tests for coating thickness, continuity, flexibility and adhesion are specified. If the specimen for coating thickness or flexibility fails to meet the specified requirements, two retests on random samples shall be conducted for each failed test.
SCOPE
1.1 This specification covers deformed and plain steel reinforcing bars with protective epoxy coating applied by the electrostatic spray method.
Note 1: The coating applicator is identified throughout this specification as the manufacturer.  
1.2 Other organic coatings may be used provided they meet the requirements of this specification.  
1.3 Requirements for coatings are contained in Annex A1.  
1.4 Requirements for patching material are contained in Annex A2.  
1.5 Guidelines for construction practices at the job-site are presented in Appendix X1.  
1.6 This specification is applicable for orders in either inch-pound units (as Specification A775) or SI units [as Specification A775M].  
1.7 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.  
1.8 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.  
1.9 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
