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
CuZn36Si1P (CW726R) 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 ensured the CEN that he is willing to negotiate licenses either free of
charge or under reasonable and non-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.

Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights other than those identified above. CEN shall not be held responsible for identifying any or
all such patent rights.
CEN and CENELEC maintain online lists of patents relevant to their standards. Users are encouraged to
consult the lists for the most up to date information concerning patents
(https://www.cencenelec.eu/european-standardization/ipr-and-patents/patents/).
Due to developing legislation, the composition of a material may be restricted to the composition
specified in this European Standard with respect to individual uses (e.g. for the use in contact with
drinking water in some Member States of the European Union). These individual restrictions are not part
of this European Standard. Nevertheless, for materials for which traditional and major uses are affected,
these restrictions are indicated. The absence of an indication, however, does not imply that the material
can be used in any application without any legal restriction.
