Active Standard ASTM A934 / A934M | Developed by Subcommittee: A01.05
Book of Standards Volume: 01.04
Historical (view previous versions of standard)
This specification covers deformed and plain steel reinforcing bars. Steel samples shall be blast cleaned and shall be coated with a protective fusion-bonded epoxy coating by electrostatic spray or other suitable method. The steel specimens shall undergo deformation test, holiday checks, bending tests, and cathodic disbondment test. The steels materials shall conform to the required values of coating thickness, continuity, flexibility, adhesion.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
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.
1.4 Requirements for epoxy coatings are contained in Annex A1.
1.5 Guidelines for application process and product test procedures of epoxy coatings for steel reinforcing bars are presented in Appendix X1.
1.6 Guidelines for construction practices at the job-site for coated steel reinforcing bars are presented in Appendix X2.
1.8 The values stated in either SI units or inch-pound 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.
