    This specification covers a group of general requirements for wrought seamless copper and copper alloy tube. The material shall be produced by either hot or cold working operations, or both, and shall be finished, unless otherwise specified, by such cold working and annealing or heat treatment as necessary to meet the properties specified. Dimensional requirements such as wall thickness are specified. The sampling requirements including lot size, portion size, and selection of sample pieces are given. Requirements for chemical analysis, and tension, microscopical examination, Rockwell hardness, grain size, expansion (pin), mercurous nitrate, and electrical resistivity tests are detailed. The material shall conform to the prescribed chemical composition, hardness, electrical resistivity, tensile strength, yield strength, elongation, and grain size.
