1、Designation: B 927 03Standard Specification forBrass Rod, Bar, and Shapes1This standard is issued under the fixed designation B 927; 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
2、 indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification establishes requirements for brass rod(round, hexagonal, and octagonal), bar (rectangular andsquare), and shapes of UNS Alloys C21000, C
3、22000, C23000,C24000, C26000, C26800, C27000, and C27400.1.2 UnitsThe values stated in either inch-pound or SIunits are to be regarded separately as standard. Within the textand tables, the SI units are shown in brackets. The values statedin each system may not be exact equivalents; therefore, eachs
4、ystem shall be used independently of the other. Combiningvalues from the two systems may result in nonconformancewith the standard.2.
