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 shall be 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 shall be 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 property requirements;
Y. Material condition designated by the minimum value of yield strength requirement for the
product with mandatory tensile property requirements;
H. Material condition designated by the minimum value of hardness requirement for the
product with mandatory hardness requirements;
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 m), list entry n) and 8.4].
Exact conversion between material conditions designated R. and H. is not possible.
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 is 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 (Rod);
— number of this document (EN 12163);
— 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 (see
Bibliography [4]);
— material condition designation (see Tables 9 to 16);
— cross-sectional shape (the following designations shall be used, as appropriate: RND for round, SQR
for square, HEX for hexagonal, OCT for octagonal);
— nominal cross-sectional dimension (diameter or width across-flats);
— tolerance class (see Table 17);
— for polygonal rod, the corner shape (the following designations shall be used as appropriate: SH for
sharp, RD for rounded), (see Table 19).
The derivation of a product designation is shown in the following examples.
EXAMPLE 1 Rod for general purposes conforming to this standard, in material designated either CuZn40 or
CW509L, for standard applications, in material condition R410, hexagonal, nominal width across-flats 14 mm,
tolerance Class B, rounded corners, will be designated as follows:

7.1 General
When required or for use in cases of dispute, an inspection lot shall be sampled in accordance with 7.2 to
7.4.
7.2 Analysis
The sampling rate shall be in accordance with Table 21. A test sample, depending on the analytical
technique to be employed, shall be prepared from each sampling unit and used for the determination of
the composition.
When preparing the test sample, care should be taken to avoid contaminating or overheating the test
sample. Carbide tipped tools are recommended; steel tools, if used, should be made of magnetic material
to assist in the subsequent removal of extraneous iron. If the test samples are in finely divided form (e.g.
drillings, millings), they should be treated carefully with a strong magnet to remove any particles of iron
introduced during preparation.
In cases of dispute concerning the results of analysis, the full procedure given in ISO 1811-2 should be
followed.
Results may be used from analyses carried out at an earlier stage of manufacturing the product, e.g. at the
casting stage, if the material identity is maintained and if the manufacturer can ensure the traceability of
the product.
7.3 Mechanical tests
The sampling rate shall be in accordance with Table 21. Sampling units shall be selected from the finished
products. The test samples shall be cut from the sampling units. Test samples, and test pieces prepared
from them, shall not be subjected to any further treatment, other than any machining operations
necessary in the preparation of the test pieces.
7.4 Dezincification resistance and stress corrosion resistance test
The sampling rate which shall be applied to finished products shall be:
— for products that have been heat treated: one sampling unit per heat treatment batch;
— for products that have not been heat treated: in accordance with Table 21.
The test samples shall be cut from the sampling units. Test samples, and test pieces prepared from them,
shall not be subjected to any further treatment, other than any machining operations necessary in the
preparation of the test pieces.
8 Test methods
8.1 Analysis
Analysis shall be carried out on the test pieces, or test portions, prepared from the test samples obtained
in accordance with 7.2. Except in cases of dispute, the analytical methods used shall be at the discretion
of the supplier. In cases of dispute the methods of analysis to be used shall be agreed between the
disputing parties. For expression of results, the rounding rules given in 8.8 shall be used.
8.2 Tensile test
8.2.1 General
Tensile test pieces shall be prepared in accordance with 8.2.2 and 8.2.3 and the test shall be carried out
in accordance with 8.2.4.
8.2.2 Location of test pieces
Test pieces shall be machined from one of the following locations in the test sample obtained in
accordance with 7.3:
a) for test samples from products up to and including 30 mm diameter, or width across-flats, the test
piece shall be coaxial with the product;
b) for test samples from products over 30 mm diameter, or width across-flats, the longitudinal axis of
the test piece shall be parallel to that of the product and shall be between 15 mm and 20 mm from
the surface of the product.
8.2.3 Shape and size of test pieces
Test pieces shall be in accordance with EN ISO 6892-1:2019, except that 200 mm gauge length is not
permitted.

S S o
o o
is the original cross-sectional area of the test piece in square millimetres.
8.2.4 Procedure for testing
The tensile test shall be carried out in accordance with the method given in EN ISO 6892-1:2019.
8.2.5 Determination of results
The tensile strength and the elongation shall be determined from the tensile test results obtained in
accordance with 8.2.4. For expression of results, the rounding rules given in 8.8 shall be used.
8.3 Hardness test
Hardness shall be determined on test pieces cut from the test sample obtained in accordance with 7.3.
The test shall be carried out in accordance with EN ISO 6506-1:2014.
The position of the impression/indentation shall be:
a) for rod of diameter or width across-flats less than 5 mm upon agreement between the involved
parties;
b) for rod of diameter or width across-flats greater (equal) than 5 mm on the cross-section of the
product midway between the central axis and the outside surface.
8.4 Dezincification resistance test
The test method given in EN ISO 6509-1:2014 shall be used on the test samples obtained in accordance
with 7.4 [see Clause 5 list entry l)].
A test piece shall be taken from each test sample so as to expose a prepared cross-sectional surface to the
test solution.
At the completion of the test the maximum depth of dezincification in a longitudinal direction shall be
measured;
8.5 Stress corrosion resistance test
The test method given in either ISO 6957:1988 (using pH 10,0) or EN 14977:2006 shall be used on the
test pieces prepared from the test samples obtained in accordance with 7.4. The choice of which of these
tests is used shall be at the discretion of the supplier, unless a preference is agreed at the time of the order
[see Clause 5 list entry m)].
8.6 Determination of the electrical conductivity
If not otherwise specified the test method is left to the discretion of the supplier, e.g. eddy current method
or resistance bridge.
8.7 Retests
8.7.1 Analysis, tensile, hardness and dezincification resistance tests and determination of the
electrical conductivity
If there is a failure of one, or more than one, of the tests in 8.1, 8.2, 8.3 or 8.6, two test samples from the
same inspection lot shall be permitted to be selected for retesting the failed property (properties). One
of these test samples shall be taken from the same sampling unit as that from which the original failed
test piece was taken, unless that sampling unit is no longer available, or has been withdrawn by the
supplier.
If the test pieces from both test samples pass the appropriate test(s), then the inspection lot represented
shall be deemed to conform to the particular requirement(s) of this standard. If a test piece fails a test,
the inspection lot represented shall be deemed not to conform to this standard.
NOTE If an inspection lot of alloy CuZn38As (CW511L) fails the dezincification resistance test when tested or
retested, the supplier has the option to heat treat, or to further heat treat, the inspection lot and resubmit it for all
the tests called for on the order, except for analysis.
8.7.2 Stress corrosion resistance test
If a test piece fails the test in 8.5, the inspection lot represented by the failed test piece shall be permitted
to be subjected to a stress relieving treatment. A further test sample shall then be selected in accordance
with 7.4.
If a test piece from the further test sample passes the test, the stress relieved product shall be deemed to
conform to the requirements of this standard for residual stress level and shall then be subjected to all
the other tests called for on the order, except for analysis. If the test piece from the further test sample
fails the test, the stress relieved product shall be deemed not to conform to this standard.
8.8 Rounding of results
For the purpose of determining conformity to the limits specified in this standard an observed or a
calculated value obtained from a test shall be rounded in accordance with the following procedure, which
is based upon the guidance given in EN ISO 80000-1. It shall be rounded in one step to the same number
of figures used to express the specified limit in this European Standard. Except for tensile strength and
0,2 % proof strength the rounding interval shall be 10 N/mm and for elongation the value shall be
rounded to the nearest 1 %.
The following rules shall be used for rounding:
a) if the figure immediately after the last figure to be retained is less than 5, the last figure to be retained
shall be kept unchanged;
b) if the figure immediately after the last figure to be retained is equal to or greater than 5, the last figure
to be retained shall be increased by one.
9 Certificate of compliance and inspection documentation
9.1 Certificate of compliance
When requested and agreed at the time of the order [see Clause 5 list entry p)] the appropriate certificate
of compliance shall be issued for the products. The relevant information is available in
EN ISO/IEC 17050-1:2010 and EN ISO/IEC 17050-2:2004.
9.2 Inspection documentation
When requested and agreed at the time of the order [(see Clause 5 list entry q)] the appropriate
inspection document, in accordance with EN 10204:2004 shall be issued for the products.
For pressure equipment applications, the equipment manufacturer has the obligation to request the
appropriate inspection documentation according to the applicable product or application standard(s),
EN 764-5:2014 and EN 10204:2004.
10 Marking, packaging, labelling
Unless otherwise specified at the time of the order, the marking, packaging and labelling shall be left to
the discretion of the supplier [see Clause 5 list entry r)].
