Committee CEN/TC 133 "Copper and copper alloys", the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2000, and conflicting national standards shall be withdrawn at the latest by January 2000. According to the CENCENELEC Internal Regulations, the national standards organizations of the following countries are bound to impiement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This European Standard is considered to be a supporting standard to those application and product standards which in themselves support an essential safety requirement of a New Approach Directive and which make reference to this European Standard. Within its programme of work, Technical Committee CEN/TC 133 requested CEN/TC 133/WG 3.2 "Tubes for general purposes" to prepare the following standard: EN 12449 Copper and copper alloys - Seamless, round tubes for general purposes This is one of a series of European Standards for copper and copper alloy tubes. Other products are, or will be, specified as follows: EN 1057 Copper and copper alloys - Seamless, round copper tubes for water and gas in sanitary and heating applications EN 12450 Copper and copper alloys - Seamless, round copper capillary tubes EN 12451 Copper and copper alloys - Seamless, round tubes for heat exchangers EN 12452 Copper and copper alloys - Rolled, finned, seamless tubes for heat exchangers prEN 12735-1 Copper and copper alloys - Seamless, round copper tubes for air conditioning and refrigeration - Part 1: Tubes for piping systems prEN 12735-2 Copper and copper alloys - Seamless, round copper tubes for air conditioning and refrigeration - Part 2: Tubes for equipment prEN 13348 Copper and copper alloys - Seamless, round copper tubes for medical gases prEN 13349 Copper and copper alloys - Pre-insulated copper tubes with solid covering prEN 13600 Copper and copper alloys - Seamless copper tubes for electrical purposes 0 BSI 11-1 999 COPYRIGHT European Committee for Standardization Licensed by Information Handling Services COPYRIGHT European Committee for Standardization Licensed by Information Handling Services STD-BSI BS EN 12449-ENGL 1999 m 1624bb9 0805608 566 Page 4 EN 12449:1999 1 scope This European Standard specifies the composition, properiy requirements and tolerances on dimensions and form for seamless round drawn copper and copper alloy tubes for general purposes supplied in 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. NOTE: 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 the free machining purposes which are specified in EN 12168. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references, the latest edition of the publication referred to applies.

NOTE: Although material symbol designations used in this standard might be the same as those in other standards using the designation system given in IS0 1190-1, the detailed composition requirements are not necessarily the same. 4.1.3 Number The material number designation is in accordance with the system given in EN 141 2. 4.2 Materlal condition For the purposes of this standard, the following designations, which are in accordance with the system given in EN 1 173, apply for the material condition: M Material condition for the product as manufactured without specified mechanical properties; R... Material condition designated by the minimum value of tensile strength requirement for the product with mandatory tensile property requirements; H... Material condition designated by the minimum value of hardness requirement for the product with mandatory hardness requirements. NOTE 1: Products in the H... condition can be specified to Vickers or Brinell hardness. The matenal condition designation H... is the same for both hardness test methods. S (suffix) Material condition for a product which is stress relieved. NOTE 2: Products in the M, R... or H... condition can be specially processed (¡.e. mechanically or thermally stress relieved) in order to lower the residual stress level to improve the resistance to stress corrosion (see 6.5.2). Exact conversion between the material conditions designated R... and H... is not possible. Except when the cuff ix S is used, material condition is designated by only one of the above designations.
