Title (english): Copper and copper alloys - Seamless, round tubes for general purposes; German version EN 12449:2012

Document type: Standard

Publication date: 2012-07


This European Standard specifies the composition, property requirements and tolerances on dimensions and form for seamless round drawn copper and copper alloy tubes for general purposes. It applies for the size range from 3 mm up to and including 450 mm outside diameter and from 0,3 mm up to and including 20 mm wall thickness. The sampling procedures and the methods of test for verification of conformity to the requirements of this standard are also specified. Tubes having an outside diameter less than 80 mm and/or a wall thickness greater than 2 mm in certain alloys are most frequently used for free machining purposes. These tubes are specified in EN 12168. The European Committee for Standardization (CEN) draws attention to the fact that it is claimed that compliance with this document may involve the use of a patent concerning the alloy CuSi3Zn2P (CW121C) and CuZn21Si3P (CW724R). This European Standard has been prepared by Technical Committee CEN/TC 133 "Copper and copper alloys" (secretariat: DIN, Germany) of the European Committee for Standardization (CEN). Regarding the German collaboration, the responsible committee is Working Committee NA 066-02-03 AA "Kupferrohre (Installation und Industrie)" ("Copper tubes (Installation and industrial)") of the Non-ferrous Metals Standards Committee (FNNE).
