Designation:B139/B139M12(Reapproved 2017)Standard Specification forPhosphor Bronze Rod,Bar,and Shapes1This standard is issued under the fixed designation B139/B139M;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 establishes the requirements for phos-phor bronze rod,bar,and shapes.1.2 UnitsValues stated in either inch-pound units or SIunits are to be regarded separately as standard.Within the text,SI units are shown in brackets.The values stated in eachsystem may not be exact equivalents;therefore,each systemshall be used independently of the other.Combining valuesfrom the two systems may result in nonconformance with thespecification.1.3 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
