ASTM B927-08

Standard Specification for Brass Rod, Bar, and Shapes

SCOPE
1.1 This specification establishes requirements for brass rod (round, hexagonal, and octagonal), bar (rectangular and square), and shapes of UNS Alloys C21000, C22000, C23000, C24000, C26000, C26800, C27000, and C27400.
1.2 Units—The values stated in either inch-pound or SI units are to be regarded separately as standard. Within the text and tables, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
