This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 133.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and

European foreword
This document (prEN 12166:2022) 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 12166:2016.
In comparison with EN 12166:2016, the following significant technical changes were made:
a) Modified the definition of diameter or width across-flats at 6.4.1;
b) Modified 6.4.2 with the introduction of 6.4.2.1 Round wire and 6.4.2.2 Wire with square or regular
cross-section;
c) Introduction in 6.6 of eddy current test parameters;
d) Introduction of 6.7 Internal inclusion;
e) CuPb1P (CW113C) added in Table 1and Table 7;
f) CuSn5 (CW451K) added in Table 3 and Table 9;
g) Added a new alloy CuZn36Si1P (CW726R) in Table 6 and Table 12;
h) Introduction in the chemical composition Tables of a footnote to explain the meaning of elements for
which no upper and lower limits are defined;
i) Chemical composition of CuZn39Pb3 (CW614N) and CuZn40Pb2 (CW617N) modified in Table 5;
j) Added a new alloy CuZn40Pb1 (CW627N) in Table 5 and Table 11;
k) Table 19 added;
l) Annex ZA added.
This document is one of a series of European Standards for the copper and copper alloy products rod,
wire, profile and forgings. Other products are specified as follows:
— EN 12163, Copper and copper alloys — Rod for general purposes;

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.
Information may be obtained from:

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
(ftp://ftp.cencenelec.eu/EN/IPR/Patents/IPRdeclaration.pdf).
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.
