Full Description

1.1This specification establishes general requirements common to ASTM copper alloy casting specifications B22/B22M, B61, B62, B66, B67, B148, B176, B271/B271M, B369, B427, B505/B505M, B584, B763/B763M, B770, and B806. These requirements apply to the casting specifications to the extent referenced therein.

1.1.1In the event of conflict between this specification and a casting specification, the requirements of the casting specification shall take precedence.

1.2The chemical composition and other requirements not included in this specification shall be prescribed in the casting product specifications.

1.3Units-The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4No precise quantitative relationship can be stated between the properties of the metal in various locations of the same casting or between the properties of castings and those of a test bar casting from the same metal. (See Appendix X1.)2

1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
