European foreword
This document (prEN 12165:2022) has been prepared by Technical Committee CEN/TC 133 “Copper
and copper alloys”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 12165:2016
In comparison with EN 12165:2016, the following significant technical changes were made:
a) Introduction in the § 6.5 of eddy current test parameters;
b) Introduction of the § 6.6 Internal inclusion;
c) Modified the definition of diameter at § 6.4.1;
d) Added a new Figure for straightness at § 6.4.4 and modified values in Table 11;
e) Introduction in the chemical composition Tables of a footnote to explain the meaning of elements
for which no upper and lower limits are defined;
f) CuZn4Si4MnP (CW245E) and CuZn9Si4MnP (CW246E) added in the new Table 3
g) Chemical composition of CuZn39Pb3 (CW614N), CuZn40Pb2 (CW617N), CuZn35Pb1,5AlAs
(CW625N) and CuZn33Pb1,5AlAs (CW626N) modified in Table 8;
h) Added a new alloy CuZn40Pb1 (CW627N) in Table 8;
i) Chemical composition of CuZn33Pb1AlSiAs (CW725R) modified in Table 9;
j) Added a new alloy CuZn36Si1P (CW726R) in Table 9;
k) Removed Tables of Mechanical properties (old Table 9, Table 10, Table 11, Table 12, Table 13,
Table 14, Table 15 and Table 16);
l) Renamed Table 17 in Table 10, Table 18 in Table 11, Table 19 in Table 12;
m) Added new Table 13.

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 alloys
CuZn4Si4MnP (CW245E), CuZn9Si4MnP (CW246E), CuZn33Pb1AlSiAs (CW725R), and
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.

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.
