EN 12449:2016 (E)4BS EN 12449:2016EN 12449:2016 (E) 5 Introduction 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 CuSi3

44、Zn2P (CW124C) 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 patent right has assured the CEN that he is willing to negotiate licenses under reasonable and not-discriminatory terms and conditions with a

45、pplicants throughout the world. In this respect, the statement of the holder of this patent right is registered with CEN. For CuSi3Zn2P (CW124C) information may be obtained from: VIEGA GmbH R. material condition designated by the minimum value of tensile strength requirement for the product with man

46、datory tensile property requirements; H. material condition designated by the minimum value of hardness requirement for the product with mandatory hardness requirements. BS EN 12449:2016EN 12449:2016 (E)7BS EN 12449:2016EN 12449:2016 (E) 8 NOTE 1 Products in the H. condition can be specified to Vick

47、ers 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. NOTE 2 Products in the M, R. or H. condition can be specially processed (i.e. mechanically or thermally stress relieved) in

48、 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 suffix S is used, material condition is designated by only one of the above designations. 4.3 Pr

49、oduct 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 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 (Tube); number of this
