Anotace textu normy ASTM B30-23 :

This specification establishes the requirements for copper alloys in ingot form that shall be subjected to remelting for the manufacture of castings having the Copper Alloy UNS No. designations specified and enumerated herein. Any material and manufacturing process may be used so long as the alloy is of the required composition and mechanical characteristics, and the yielded ingot is free of defects of a kind that would render it unsuitable for remelting. Materials shall hence be sampled, prepared, and tested accordingly to examine their conformance to mechanical, chemical composition, and weldability requirements.

1. Scope

1.1?This specification covers the requirements for copper alloys in ingot and other forms including granules, nuggets, pellets, or shot for remelting for the manufacturing of castings having the Copper Alloy UNS No. designation, commercial designations and nominal composition shown in Table 1 and Table 2. Product delivered in forms other than ingot shall be upon agreement between the supplier and purchaser.

1.2?A cross reference of Copper Alloy UNS Nos. and copper alloy casting specifications is given in Table 3.

1.3?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?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.
