Significance and Use

14.1 For the purpose of determining compliance with the specified limits for requirements of the properties listed in the following table, an observed value or a calculated value shall be rounded as indicated in accordance with the rounding method of Practice E29.

Property	Rounded Limit for Observed or Calculated Value

Chemical Composition Hardness Electrical Resistivity Electrical Conductivity	nearest unit in the last right-hand significance digit used in expressing the limiting value

Tensile Strength	nearest ksi (5 MPa)
Yield Strength

Elongation	nearest 1 %

Grain Size:
Under 0.060 mm	nearest multiple of 0.005 mm
0.060 mm and over	nearest 0.01 mm

1. Scope

1.1 This 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.

1.1.1 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 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.

1.4 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.)2

1.5 This 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.
