This European Standard shall be given the status of a national s
23、tandard, either by publication of an identical text or by endorsement, at the latest by October 2012, and conflicting national standards shall be withdrawn at the latest by October 2012. This document supersedes EN 12449:1999. Within its programme of work, Technical Committee CEN/TC 133 requested CE
24、N/TC 133/WG 3 “Copper tubes (installation and industrial)“ to revise the following standard: EN 12449:1999, Copper and copper alloys Seamless, round tubes for general purposes.

33、ws 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) given in 6.1. CEN takes no position concerning the evidence, validity and scope of this patent right. The holder of this pate
34、nt right has assured the CEN that he is willing to negotiate licenses under reasonable and not-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the holder of this patent right is registered with CEN. For CuSi3Zn2P (CW121C) information may be

39、l The material is designated either by symbol or number (see Tables 1 to 8). 4.1.2 Symbol The material symbol designation is based on the designation system given in ISO 1190-1. NOTE Although material symbol designations used in this standard might be the same as those in other standards using the d
40、esignation system given in ISO 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 1412. 4.2 Material condition For the purposes of this standard, the following designations, which are i
41、n accordance with the system given in EN 1173, 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
42、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 material condition designation H. is the same for both h
43、ardness test methods. S (suffix) material condition for a product which is stress relieved.

44、TE 2 Products in the M, R. or H. condition can be specially processed (i.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 p
45、ossible. Except when the suffix S is used, material condition is designated by only one of the above designations. 4.3 Product The product designation provides a standardized pattern of designation from which a rapid and unequivocal description of a product is conveyed in communication. It provides
46、mutual comprehension at the international level with regard to products which meet the requirements of the relevant European Standard. The product designation is no substitute for the full content of the standard. The product designation for products to this standard shall consist of: denomination (
47、Tube); number of this European Standard (EN 12449); material designation, either symbol or number (see Tables 1 to 8); material condition designation (see Tables 9 to 15); nominal cross-sectional dimensions, either outside diameter (OD) and wall thickness or inside diameter (ID) and wall thickness (see 6.3). The derivation of a product designation is shown in Example 1. EXAMPLE 1 Tube conforming to this standard, in material designated either CuNi10Fe1Mn or CW352H, in material condition H075, nominal outside diameter 22 mm, nominal wall thickness 2,0 mm, shall
