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.
