1.1 This specification2 establishes the requirements for copper-alloy plate, sheet, and circles cut from plate and sheet for pressure vessels, condensers, and heat exchangers. The following alloys are covered: Copper Alloy Previously Used Designation C36500 Leaded Muntz Metal C44300 Admirality, Arsenical C44400 Admirality, Antimonial C44500 Admirality, Phosphorized C46400 Naval Brass, Uninhibited C46500 Naval Brass, Arsenical C61300 Aluminum Bronze C61400 Aluminum Bronze D C63000 10 % Aluminum-Nickel Bronze C63200 9 % Aluminum-Nickel Bronze C70600 90-10 Copper Nickel C70620 90-10 Copper Nickel-(modified for welding) C71500 70-30 Copper Nickel C71520 70-30 Copper Nickel-(modified for welding) C72200 . . .
1.2 Units—The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 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.
