Standard Specification for Seamless Copper Alloy Pipe and Tube
This specification establishes the requirements for seamless, copper alloy pipe and tube in nominal pipe sizes, both regular and extra-strong, and seamless tube in straight lengths for general engineering purposes. The material of manufacture shall be a cast billet, bar, or tube. The product shall be produced by hot-working or cold-working operations, or both. Unless otherwise specified, the product shall be finished by such cold working and annealing or heat treatment. Only tensile, yield, or elongation test results shall be a basis for rejection based upon mechanical properties. At least two replicate analyses for each element with a limiting value shall be conducted under chemical analysis. The test specimen shall be of the size and shape to permit testing with the available test equipment. The surface of the specimen shall be sufficiently flat and smooth to permit the accurate determination of hardness and shall be sufficiently free of scale and foreign material to permit the accurate determination of hardness. Care shall be taken to avoid changing the material's condition through either cold working or heating, or both. The product shall be free from defects, but blemishes of a nature that do not interfere with the intended application are acceptable.
1.1 This specification2 establishes the requirements for seamless, copper alloy pipe and tube in nominal pipe sizes, both regular and extra strong, and seamless tube in straight lengths for general engineering purposes. Pipe and tube are produced in the copper alloy UNS Numbers: C61300, C61400, C63020, C65100, and C65500.
1.2 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.
1.3 The following safety caveat pertains only to the test method(s) described in this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
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.
