33、on (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 (CW124C) and CuZn21Si3P (CW724R) given in 6.1. CEN takes no position concerning the evidence, validity and scope of this patent right. The holder
34、of this patent 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 (CW124C) inform
35、ation may be obtained from: VIEGA GmbH 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 hard
36、ness requirements. EN 12449:2016 (E) DIN EN 12449:2016-11 8 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 hardness test methods. S (suffix) material condition for a product which is stress relieved. NOT
37、E 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 po
38、ssible. 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 m
39、utual 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 (T
40、ube); 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 (s
41、ee 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, will be designated as follows: Tube EN 1
42、2449 CuNi10Fe1Mn H075 OD22 2,0 or Tube EN 12449 CW352H H075 OD22 2,0 Denomination Number of this European Standard Material designation Material condition designation Nominal cross-sectional dimensions in millimetres EN 12449:2016 (E) DIN EN 12449:2016-11 9 EXAMPLE 2 Tube conforming to this standard
43、, in material designated either CuZn37 or CW508L, in material condition M, stress relieved, nominal inside diameter 30 mm, nominal wall thickness 2,5 mm, will be designated as follows: Tube EN 12449 CuZn37 MS ID30 2,5 or Tube EN 12449 CW508L MS ID30 2,5 5 Ordering information In order to facilitate
44、the enquiry, order and confirmation of order procedures between the purchaser and the supplier, the purchaser shall state on his enquiry and order the following information: a) quantity of product required (number of pieces, length or mass); b) denomination (Tube); c) number of this European Standar
45、d (EN 12449); d) material designation (see Tables 1 to 8); e) material condition designation (see 4.2 and Tables 9 to 15) if it is other than M; f) nominal cross-sectional dimensions either outside diameter (OD) and wall thickness or inside diameter (ID) and wall thickness (see 6.3); g) length, eith
46、er nominal together with tolerance required, or fixed length (see 6.3.4). NOTE 1 It is advised that the product designation, as described in 4.3, is used for items b) to f). In addition, the purchaser shall also state on the enquiry and order any of the following, if required: h) whether the tubes a
47、re for sea water application (see Table 3). If so, the composition limits required; i) test method to be used for the measurement of hardness, i.e. Vickers or Brinell (see 8.3); j) where dimensional tolerances are to be applied, if not on the outside diameter and wall thickness (see 6.3.1); k) wheth
48、er the tubes are required to pass a drift expanding test (see 6.5.1); l) whether the tubes are required to pass a stress corrosion resistance test (see 6.5.2); m) whether the tubes are required to meet a grain size requirement (see 6.5.3); if so, the grain size limits required; NOTE 2 It is advised
49、to agree the grain size limits between the purchaser and the supplier. n) whether the tubes are required to pass freedom from defects tests (see 6.5.4); if so, which test method is to be used (see 8.5), if the choice is not to be left to the discretion of the supplier, and the acceptance criteria if they are not to be left to the discretion of the supplier
