Designation:A775/A775M17Standard Specification forEpoxy-Coated Steel Reinforcing Bars1This standard is issued under the fixed designation A775/A775M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This specification covers deformed and plain steelreinforcing bars with protective epoxy coating applied by theelectrostatic spray method.NOTE1The coating applicator is identified throughout this specifica-tion as the manufacturer.1.2 Other organic coatings may be used provided they meetthe requirements of this specification.1.3 Requirements for coatings are contained in Annex A1.1.4 Requirements for patching material are contained inAnnex A2.1.5 Guidelines for construction practices at the job-site arepresented in Appendix X1.1.6 This specification is applicable for orders in either SIunits(as Specification A775M)or inch-pound units as Speci-fication A775.1.7 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.8 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2A615/A615M Specification for Deformed and Plain Carbon-Steel Bars for Concrete ReinforcementA706/A706M Specification for Deformed and Plain Low-Alloy Steel Bars for Concrete ReinforcementA944 Test Method for Comparing Bond Strength of SteelReinforcing Bars to Concrete Using Beam-End Speci-mensA996/A996M Specification for Rail-Steel and Axle-SteelDeformed Bars for Concrete ReinforcementB117 Practice for Operating Salt Spray(Fog)ApparatusD374 Test Methods for Thickness of Solid Electrical Insu-lation(Metric)D0374_D0374MD2967 Test Method for Corner Coverage of Powder Coat-ingsD4060 Test Method for Abrasion Resistance of OrganicCoatings by the Taber AbraserG8 Test Methods for Cathodic Disbonding of Pipeline Coat-ingsG14 Test Method for Impact Resistance of Pipeline Coatings(Falling Weight Test)G20 Test Method for Chemical Resistance of Pipeline Coat-ingsG62 Test Methods for Holiday Detection in Pipeline Coat-ings2.2 NACE Standards:3RP-287-87 Field Measurement of Surface Profile of Abra-sive Blast-Cleaned Steel Surface Using a Replica Tape2.3 SSPC Specifications:4SSPC-PA 2 Measurement of Dry Coating Thickness withMagnetic GagesSSPC-SP 10 Near-White Blast CleaningSSPC-VIS 1 Pictorial Surface Preparation Standards forPainting Steel Surfaces2.4 CRSI Documents:5“Voluntary Certification Program for Fusion Bonded EpoxyCoating Applicator Plants”1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.05 on Steel Reinforcement.Current edition approved Jan.1,2017.Published January 2017.Originallyapproved in 1981.Last previous edition approved in 2016 as A775/A775M 16.DOI:10.1520/A0775_A0775M-17.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from NACE International(NACE),1440 South Creek Dr.,Houston,TX 77084-4906,http:/www.nace.org.4Available from Society for Protective Coatings(SSPC),40 24th St.,6th Floor,Pittsburgh,PA 15222-4656,http:/www.sspc.org.5Available from Concrete Reinforcing Steel Institute(CRSI),933 North PlumGrove Rd.,Schaumburg,IL 601734758,http:/www.crsi.org.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 2.5ACI Standards:6ACI 301 Specifications for Structural Concrete3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 conversion coating,npreparation of the blast-cleaned steel surface prior to coating application that isdesigned to pretreat the metal to promote coating adhesion,reduce metal-coating reactions,improve corrosion resistance,and increase bliste
