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.

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.

4 Designations
4.1 Material
4.1.1 General
The material is designated either by symbol or by number (see Tables 1 to 8).
4.1.2 Symbol
The material symbol designation is based on the designation system given in ISO 1190-1:1982.
NOTE Although material symbol designations used in this standard might be the same as those in other
standards using the designation system given in ISO 1190-1:1982, the detailed composition requirements are not
necessarily the same.
4.1.3 Number
The material number designation is in accordance with the system given in EN 1412:2016.
4.2 Material condition
For the purposes of this document, the following designations, which are in accordance with the system
given in EN 1173:2008, apply for the material condition:
M material condition for the product as manufactured, without specified mechanical
properties;
R. material condition designated by the minimum value of tensile strength requirement for
the product with mandatory tensile strength requirement;
H. material condition designated by the minimum value of hardness requirement for the
product with mandatory hardness requirement;
S (suffix) material condition for a product which is stress relieved.
Products in the M, R. or H. material condition may be specially processed (i.e. mechanically or thermally
stress relieved) in order to lower the residual stress level to improve the resistance to stress corrosion
and the dimensional stability on machining [see Clause 5 list entry i), list entry j) and 8.5].
Exact conversion between material conditions designated R. and H. is not possible.

---------------------- Page: 9 ----------------------
oSIST prEN 12167:2022
prEN 12167:2022 (E)
Except when the suffix S is used, material condition is designated by only one of the above designations.
4.3 Product
The product designation provides a standardized pattern of designation from which a rapid and
unequivocal description of a product can be 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 (profile or bar);
— number of this document (EN 12167);
— material designation, either symbol or number (see Tables 1 to 8);
— DW for compliance in the chemical composition according to the 4 MS Common Composition List. This
information is mandatory in the case in which the product is used for drinking water applications
according to the 4 MS Common Composition List and not to be given in other cases;
— material condition designation (see Tables 9 to 16);
— for profiles, the number of the profile or a fully dimensioned and toleranced drawing;
— for profiles with L-, T-, U-shaped cross-sections, the nominal cross-sectional dimensions;
— for bar, the nominal cross-sectional dimensions;
— for bar and profiles with L-, T-, U-shaped cross-sections, the tolerance class (see Table 17 to 19);
— for bar, the corner shape (the following designations shall be used as appropriate: SH for sharp, RD for
rounded) (see Table 23).
The derivation of a product designation is shown in in the following examples.
EXAMPLE 1 Bar conforming to this standard, in material designated either CuZn40Pb2 or CW617N, for standard
applications, in material condition H110, nominal cross-sectional dimensions 30 mm × 10 mm, tolerance Class B,
with sharp corners, will be designated as follows:

6 Requirements
6.1 Composition
The composition shall conform to the requirements for the appropriate material given in Tables 1 to 8.

composition. In this case the limitations shall be specified in the ordering information [see Clause 5,
list entry f)].
6.2 Mechanical properties
6.2.1 Profiles
Mechanical properties of profiles depend on the shape, dimensions and the material. For this reason,
mechanical properties of profiles are not specified in this standard but, if needed, are subject to
agreement between the purchaser and the supplier [see Clause 5, list entry k)].

purchaser and supplier.
Products in alloys other than CuZn21Si3P (CW724R) shall be subjected to heat treatment approximately
in the range 500 °C to 550 °C. Should the user need to heat the material out of the range before specified

6.4 Residual stress level
Products ordered and supplied in the stress relieved material condition (see 4.2, 2nd paragraph) shall
show no evidence of cracking if tested. The tests shall be carried
