Designation:B81113(Reapproved 2017)Standard Specification forWrought Zirconium Alloy Seamless Tubes for NuclearReactor Fuel Cladding1This standard is issued under the fixed designation B811;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers seamless wrought zirconium-alloy tubes for nuclear fuel cladding application,in the outsidediameter(OD)size range of 0.200 in.(5.1 mm)to 0.650 in.(16.5 mm)and wall thickness range of 0.010 in.(0.25 mm)to0.035 in.(0.89 mm).1.2 Two grades of reactor grade zirconium alloys aredescribed.1.2.1 The present UNS numbers designated for the twogrades are given in Table 1.1.3 Unless a single unit is used,for example corrosion massgain in mg/dm2,the values stated in either inch-pound or SIunits are to be regarded separately as standard.The valuesstated in each system are not exact equivalents;therefore eachsystem must be used independently of the other.SI valuescannot be mixed with inch-pound values.1.4 The following precautionary caveat pertains only to thetest method portions of this specification:This standard doesnot purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the user of thisstandard to establish appropriate safety,health,and environ-mental practices and determine the applicability of regulatorylimitations prior to use.1.5 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:2B350/B350M Specification for Zirconium and ZirconiumAlloy Ingots for Nuclear ApplicationB353 Specification for Wrought Zirconium and ZirconiumAlloy Seamless and Welded Tubes for Nuclear Service(Except Nuclear Fuel Cladding)E8 Test Methods for Tension Testing of Metallic MaterialsE8M Test Methods for Tension Testing of Metallic MaterialsMetric(Withdrawn 2008)3E21 Test Methods for Elevated Temperature Tension Tests ofMetallic MaterialsE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with SpecificationsE112 Test Methods for Determining Average Grain SizeG2/G2M Test Method for Corrosion Testing of Products ofZirconium,Hafnium,and Their Alloys in Water at 680F(360C)or in Steam at 750F(400C)2.2 Other Document:ANSI B46.1 Surface Texture(Surface Roughness)43.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 dimensions,ntube dimensions are outside diameter,inside diameter,and wall thickness.Only two of these param-eters may be specified in addition to length,except minimumwall may be specified with outside and inside diameter.In eachcase,ovality and wall thickness variation(WTV)may bespecified as additional requirements.3.1.2 hydride orientation fraction,Fn,nthe ratio of hy-dride platelets oriented in the radial direction to the totalhydride platelets in the field examined.3.1.3 lot size,na lot shall consist of all tubes of the samesize,shape,condition,and finish produced from the same ingotby the same reduction schedule and heat treatment.The finalheat treatment shall be in a single furnace charge.1This specification is under the jurisdiction of ASTM Committee B10 onReactive and Refractory Metals and Alloys and is the direct responsibility ofSubcommittee B10.02 on Zirconium and Hafnium.Current edition approved Nov.1,2017.Published November 2017.Originallyapproved in 1990.Last previous edition approved in 2013 as B811 13.DOI:10.1520/B0811-13R17.2For 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.4Available from American Iron and Steel Institute(AISI),1140 ConnecticutAve.,NW,Suite 705,Washington,DC 20036,http:/www.steel.org.Copyright 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 3.1.4 mill finish tubes,ntubes that have received allfinishing operations subsequent to final anneal,which poten-tially affects tube mechanical,dimensional,or surface condi-tion.These operations include,but are not limited to,pickling,cleani
