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.

European foreword
This document (prEN 12163:2022) 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 12163:2016.
In comparison with EN 12163:2016, the following significant technical changes were made:
a) Introduction of 6.7 Internal inclusion;
b) Modified the definition of diameter or width across-flats at 6.5.1;
c) Added a new Figure for straightness at 6.5.3 and modified values in Table 18
d) CuZn4Si4MnP (CW245E) and CuZn9Si4MnP (CW246E) added in the new Table 2 and new Table 10
e) CuSn5 (CW451K) added in Table 6 and Table 14;
f) Introduction in the chemical composition Tables of a footnote to explain the meaning of elements for
which no upper and lower limits are defined;
g) Annex ZA added.
