Abstract
This specification establishes requirements for copper alloy sand castings for valve applications. The castings shall conform to the chemical composition requirements specified. Mechanical properties shall be determined from separately cast test bars, and shall conform with the requirements. Brinell hardness readings shall be taken in the grip end of the tension test bar and shall be made in accordance with the specified requirements.
Scope
1.1 This specification establishes requirements for copper alloy sand castings for valve applications. Nominal compositions of the alloys defined by this specification are shown in Table 1.2
Note 1: This specification does not cover Copper Alloy UNS Nos. C83600, C92200, C96200, and C96400. These alloys are also used in valve applications. They are covered by the following specifications: C83600: B62 C92200: B61 C96200: B369 C96400: B369
1.2 The castings produced under this specification are used in products which may be manufactured in advance and supplied for sale from stock by the manufacturer.
1.3 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
1.4 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.
