Designation:B187/B187M19Standard Specification forCopper,Bus Bar,Rod,and Shapes and General PurposeRod,Bar,and Shapes1This standard is issued under the fixed designation B187/B187M;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 specification2establishes the requirements for cop-per conductor bar,rod,and shapes for electrical(bus)applica-tions and rod,bar,and shapes for general applications.1.1.1 The products for electrical(bus)applications shall bemade from the following coppers:3Copper UNS No.3Reference

otherwise specified in the contract or purchaseorder.1.2 The product for general applications shall be made fromany of the coppers in 1.1.1 or the following coppers:Copper UNS No.3Reference DesignationC10800OFLPC12200DHP1.2.1 The product may be furnished from any copper listedabove unless otherwise specified in the contract or purchaseorder.Other coppers may be used upon agreement between thesupplier and purchaser.1.3 UnitsThe values stated in either inch-pound units orSI units are to be regarded separately as standard.Within thetext,SI units are shown in brackets.The values stated in eachsystem are not necessarily exact equivalents;therefore,toensure conformance with the standard,each system shall beused independently of the other,and values from the twosystems shall not be combined.NOTE1Material for hot forging will be found in SpecificationB124/B124M.1.4 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
