1、 Designation:B 21/B21M 01e 1Standard Specication forNaval Brass Rod, Bar, and Shapes 1This standard is issued under the xed designation B 21/B21M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number

2、 in parentheses indicates the year of last reapproval. A superscript epsilon (e indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.e 1N OTE Section 1.4was added editorially in January 2003.1. Scope *1.1

3、This specication establishes the requirements for naval brass rod, bar, and shapes produced from Copper Alloys UNS No. C46200, C46400, C47940, C48200, or C48500. 1.1.1For piston-nish rod or shafting refer to the Other Requirements Section.1.1.2For hot forging material, refer to Specication B 124/ B

4、124M.1.2Units The values stated in inch-pound units or SI units are to be regarded separately as standard. Within the text, SI units are shown in brackets. The values in each system are not exact equivalents; therefore, each system shall be used inde-pendently of the other. Combining values from the

5、 two systems may result in nonconformance with the specication. 1.3Warning Mercury is a denite health hazard in use and disposal (seePerformance Requirements.1.4This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user

6、 of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
