Designation:A109/A109M16(Reapproved 2018)Standard Specification forSteel,Strip,Carbon(0.25 Maximum Percent),Cold-Rolled1This standard is issued under the fixed designation A109/A109M;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 cold-rolled carbon steel strip incut lengths or coils,furnished to closer tolerances than cold-rolled carbon steel sheet,with specific temper,with specificedge or specific finish,and in sizes as follows:Width,in.Thickness,in.Over12to 2315160.300 and underOver 12.5 to 600 mm7.6 mm and under1.2 Cold-rolled strip is produced with a maximum specifiedcarbon not exceeding 0.25 percent.1.3 Strip tolerance products may be available in widthswider than 231516in.600 mm by agreement between pur-chaser and supplier.However,such products are technicallyclassified as cold rolled sheet.The tolerances,finishes,tempers,edges,and available widths and thicknesses differen-tiate cold rolled strip from the product known as cold rolledsheet which is defined by Specification A568/A568M and fromcold rolled high carbon strip which is defined by SpecificationA682/A682M.1.4 For the purpose of determining conformance with thisspecification,values shall be rounded to the nearest unit in theright hand place of figures used in expressing the limitingvalues in accordance with the rounding method of PracticeE29.1.5 The SI portions of the tables contained herein listpermissible variations in dimensions and mass(see Note 1)inSI(metric)units.The values listed are not exact conversions ofthe values listed in the inch-pound tables,but instead arerounded or rationalized values.Conformance to SI tolerancesis mandatory when the“M”specification is used.NOTE1The term weight is used when inch-pound units are thestandard.However,under SI the preferred term is mass.1.6 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.1.7 This specification is expressed in both inch-pound unitsand SI units.However,unless the order specifies the applicable“M”specification designation(SI units),the material shall befurnished to inch-pound units.1.8 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2A370 Test Methods and Definitions for Mechanical Testingof Steel ProductsA568/A568M Specification for Steel,Sheet,Carbon,Structural,and High-Strength,Low-Alloy,Hot-Rolled andCold-Rolled,General Requirements forA682/A682M Specification for Steel,Strip,High-Carbon,Cold-Rolled,General Requirements For(Withdrawn2009)3A700 Guide for Packaging,Marking,and Loading Methodsfor Steel Products for ShipmentA751 Test Methods,Practices,and Terminology for Chemi-cal Analysis of Steel ProductsA941 Terminology Relating to Steel,Stainless Steel,RelatedAlloys,and FerroalloysA1073/A1073M Practice for Using Hand Micrometers toMeasure the Thickness of Uncoated Steel Sheet andNonmetallic and Metallic-Coated Steel SheetE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with Specifications1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.19 on Steel Sheet and Strip.Current edition approved Nov.1,2018.Published November 2018.Originallyapproved in 1926.Last previous edition approved in 2016 as A109/A109M 16.DOI:10.1520/A0109_A0109M-18.2For 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.3The last approved version of this historical standard is referenced onwww.astm.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.
