Standard Specification for General Requirements for Copper Alloy Castings

1.1 This specification establishes general requirements common to ASTM copper alloy casting specifications B 22, B 61, B 62, B 66, B 67, B 148, B 176, B 271, B 369, B 427, B 505, B 584, B 763, B 770, and B 806. These requirements apply to the casting specifications to the extent referenced therein.

1.1.1 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 product specifications.

1.3 Units—The values stated in inch-pound units are the standard. The values given in parentheses are mathematical conversions to SI units, which are provided for information only and not considered standard.

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)
