This specification establishes the requirements for seamless round, rectangular, and square copper tube suitable for general engineering applications. The tube shall be manufactured by such hot- and cold-working processes as to produce a homogeneous, uniform wrought structure in the finished product. It shall be cold drawn to the finished size and wall thickness. The requirements and size availability of tube in the tempers shall conform to the specified requirements. Tensile and yield strength test, Rockwell hardness test, expansion test, microscopical examination, hydrogen embrittlement, electromagnetic test, hydrostatic pressure test, pneumatic pressure test, electrical resistivity, and chemical composition shall be made to conform to specified requirements.
1.1 This specification establishes the requirementsfor seamless round, rectangular, and square copper tube suitablefor general engineering applications.
1.1.1 Tubes made from any of the following CopperUNS No. designations shall be supplied unless otherwise specifiedin the contract or purchase order:
|Copper UNS No.||Type of Copper|
|C10200||Oxygen-free without residualdeoxidants|
|C10300||Oxygen-free, extra lowphosphorus|
|C10800||Oxygen-free, low phosphorus|
|C12000||Phosphorus deoxidized, low residualphosphorus|
|C12200||Phosphorus deoxidized, high residualphosphorus|
1.2 Units—The values stated in either inch-poundunits or SI units are to be regarded separately as standard. Withinthe text, SI units are shown in brackets. The values stated in eachsystem may not be exact equivalents; therefore, each system shallbe used independently of the other. Combining values from the twosystems may result in non-conformance with the standard.
1.3 Thefollowing hazard statement pertains only to the test methodsdescribed in Sections 22.214.171.124, 21.2.9, and 21.2.10 of thisspecification: This standard does not purport to address allof the safety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establishappropriate safety and health practices and determine theapplicability of regulatory limitations prior to use.
