Designation:A626/A626M16Standard Specification forTin Mill Products,Electrolytic Tin Plate,Double Reduced1This standard is issued under the fixed designation A626/A626M;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 double-reduced electrolytic tinplate produced from low-carbon cold-reduced steel furnishedin coils and cut sizes for use predominately in the manufactureof cans.It is furnished in commercially available tin coatingweights masses and is normally supplied with a trimmededge.1.2 This specification is applicable to orders in eitherinch-pound units(as A626)which is supplied in thicknessesfrom 0.0050 to 0.0118 in.or SI units as A626M which issupplied in thicknesses from 0.127 to 0.300 mm.1.3 The values stated in either inch-pound or SI units are tobe regarded as standard.Within the text,the SI units are shownin brackets.The values stated in each system are not exactequivalents.Therefore,each system must be used indepen-dently of the other.Combining values from the two systemsmay result in nonconformance with this specification.1.4 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:2A623 Specification for Tin Mill Products,General Require-mentsA623M Specification for Tin Mill Products,General Re-quirements MetricA630 Test Methods for Determination of Tin CoatingWeights for Electrolytic Tin PlateA754/A754M Test Method for Coating Weight(Mass)ofMetallic Coatings on Steel by X-Ray FluorescenceB339 Specification for Pig Tin3.Ordering Information3.1 Orders for product under this specification shall includethe following information,as required and applicable,todescribe adequately the desired product:3.1.1 Name of product(double-reduced electrolytic tinplate)(Section 1),3.1.2 Tin coating weight mass designation,and marking,ifany(Section 5,Table 1,and Fig 1 and 2),3.1.3 Surface appearance and finish(Section 6),3.1.4 Chemical treatment(Section 7),3.1.5 Oiling(Section 8),3.1.6 Thickness(Specification A623 A623M)(consistentwith the intended application),3.1.7 Coil width or cut size in increments of116in.or 1 mm,3.1.8 Due to the very distinct directional properties,rollingdirection must be specified on cut sizes by underlining the slit(rolling width)dimension(Section 4)(consistent with theintended application),3.1.9 Steel type(Specification A623 A623M),3.1.10 Mechanical requirement designation(SpecificationA623 A623M)(consistent with the intended application),3.1.11 Intended application,3.1.12 Quantity in base boxes SITAs(see Note 4),3.1.13 On coils,specify minimum or range of acceptableinside diameters.The standard inside diameter is approxi-mately 16 in.if ordered to Specification A626 410 mm ifordered to Specification A626M.Coils should be specified toa maximum coil weight if ordered to Specification A626 massif ordered to Specification A626M or maximum outsidediameter,or both,3.1.14 Packaging,3.1.15 Special requirements,where applicable(J=plate orK=plate),and3.1.16 ASTM specification number and year of issue.NOTE1A typical ordering description is as follows:1000 base boxes,double-reduced electrolytic tin plate,D50/25,melted,CDC,ATBC,0.0066-in.thickness,30 by coil,MR,DR-8 CA,for 307 by 401 weldedcan bodies in accordance with Specification A626/A626M-XX.250SITAs,double-reduced electrolytic tin plate,D 5.6 2.8,melted,CDC,1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.20 on Tin Mill Products.Current edition approved Dec.1,2016.Published December 2016.Originallyapproved in 1968.Last previous edition approved in 2013 as A626/A626M-13.DOI:10.1520/A0626_A0626M-16.2For 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.*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 States1 ATBC,0.17-mm thickness,760 by coil,MR,DR-8,for 99 by 105 mmwelded can bodies to Specification A626/A626M-XX.NOTE2A typical ordering description for cut sizes is as follows:500base boxes,single reduced electrolytic tin plate,No.25,ATBC,MR,T-2BA,7C,0.0110 in.thickness,3034in.by 30716in.,for 307 diametergeneral line ring
