1. Scope
1.1 This specification establishes the requirements for naval brass rod, bar, and shapes produced from Copper Alloys UNS No. C46200, C46400, C47940, C48200, or C48500.
1.1.1 For piston-finish rod or shafting refer to the Other Requirements Section.
1.1.2 For hot forging material, refer to Specification B 124/B 124M.
1.2 Units—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 independently of the other. Combining values from the two systems may result in nonconformance with the specification.
1.3 Warning—Mercury is a definite health hazard in use and disposal (see Performance Requirements).
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
