Designation:A 497/A 497M 07Standard Specification forSteel Welded Wire Reinforcement,Deformed,for Concrete1This standard is issued under the fixed designationA 497/A 497M;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(e)indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope*1.1 This specification covers welded wire reinforcementmade from cold-worked drawn or rolled deformed wire,or acombination of deformed and non-deformed wires,to be usedfor the reinforcement of concrete.NOTE1Welded wire for concrete reinforcement has been describedby various terms:welded wire fabric,WWF,fabric,and mesh.The wirereinforcement industry prefers the term“welded wire reinforcement”(WWF)as being more representative of the range of products beingmanufactured.Therefore,the term“welded wire fabric”has been replacedwith the term“welded wire reinforcement”in this specifcation and inother related specifications.1.2 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.2.Referenced Documents2.1 ASTM Standards:2A 82/A 82M Specification for Steel Wire,Plain,for Con-crete ReinforcementA 496/A 496M Specification for Steel Wire,Deformed,forConcrete ReinforcementA 700 Practices for Packaging,Marking,and LoadingMethods for Steel Products for Shipment2.2Military Standards:MIL-STD-129 Marking for Shipment and Storage32.3Federal Standard:Fed.Std.No.123 Marking for Shipments(Civil Agencies)32.4 ASTM Adjuncts:Testing Jig Drawing43.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 convoluted wire,nwhen wire for welded wire rein-forcement is shaped into a sinusoidal wave shape,it iscommonly referred to as convoluted wire.The wire is used inthe manufacture of cages for certain applications of concretepipe reinforcing.Only non-deformed wire is normally subjectto convolution.3.1.2 welded wire reinforcement,nas used within thescope and intent of this specification,welded wire reinforce-ment designates a material composed of cold-worked steelwire,fabricated into sheets or rolls by the process of electricresistance welding.The finished material shall consist essen-tially of a series of longitudinal and transverse wires arrangedsubstantially at right angles to each other,and welded togetherat points of intersection.4.Ordering Information4.1 It shall be the responsibility of the purchaser to specifyall requirements that are necessary for the manufacture anddelivery of the welded wire reinforcement under this specifi-cation.Such requirements to be considered include,but are notlimited to,the following:4.1.1 Quantity(weight or square area),4.1.2 Name of material(deformed welded wire reinforce-ment for concrete),4.1.3 Wire spacings and sizes,4.1.4 Minimum yield strength if Supplement S1 of Specifi-cation A 496/A 496M applies;and minimum yield strength ifwire conforming to SpecificationA 82/A 82M is to be used andSupplement S1 of Specification A 82/A 82M applies.4.1.5 Yield strength measurement.The purchaser shall havethe options described in Specification A 496/A 496M on In-spection(section 13.3),4.1.6 Request for outside inspection(if not requested,15.1applies),4.1.7 Exclusion of over-steeling,if required(see 9.4.1),4.1.8 Length and width of sheets or rolls,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 Sept.1,2007.Published October 2007.Originallyapproved in 1964.Last previous edition approved in 2006 as A 497/A 497M06e1.2For 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 Standardization Documents Order Desk,DODSSP,Bldg.4,SectionD,700RobbinsAve.,Philadelphia,PA19111-5098,http:/www.dodssp.daps.mil.4Available from ASTM International Headquarters.Order Adjunct No.ADJA0185.Original adjunct produced in 1967.1*A Summary of Changes section appears at the end of this standard.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.Copyright ASTM International Provided by IHS under license with ASTM Licensee=Committee on Institutional Cooperation/5967164001 Not for Resale,02/11/2012 15:38:36 MSTNo reproduction or networking permitted without license from IHS-,-,-4.1.9 Packaging(see Section 15),and4.1.10 ASTM designati
