1.1 This specification establishes a group of general requirements common to ASTM copper alloy casting specifications B22, B61, B62, B66, B67, B148, B176, B271, B369, B427, B505, B584, B763, B770, and B806. These requirements apply to the casting specifications to the extent referenced therein. In the event of conflict between this specification and a casting specification, the requirements of the casting specification shall take precedence.

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

1.3 The values stated in inch-pound units are the standard. SI values given in parentheses are for information only.

1.4 No 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.)
