Products in CuZn21Si3P (CW724R) that have passed the test shall be marked with “Si”. NOTE The as-supplied forging stock may not necessarily meet this requirement unless suitably heat treated as described in 8.3. The test is intended to demonstrate that forgings produced from the stock are capable of being processed so as to pass the test requirement. 6.4 Dimensions and tolerances 6.4.1 Diameter The diameter shall conform to the tolerances given in Table 17 for class A or class B, as appropriate to the order [see 5 g)]. The diameter is calculated as the mean of one or more pairs of measurements taken at right angles at the same cross-section of the rod. SIST EN 12165:2011
EN 12165:2011 (E) 11 6.4.2 Deviation from circular form
For round rod the deviation from circular form shall not exceed half the range of the tolerance on diameter given in Table 17. 6.4.3 Length The forging stock shall have length and length tolerances agreed between customer and supplier. 6.4.4 Straightness For round rod of diameter from 10 mm up to and including 50 mm of length 1 000 mm or over, the deviation from straightness, defined as the curvature (depth of arc) against a datum line when the product is lying flat in a horizontal plane, shall conform to the tolerances given in Table 18. 7 Sampling 7.1 General When required (e.g. if necessary in accordance with specified procedures of a supplier’s quality system, or when the purchaser requests inspection documents with test results, or for use in cases of dispute), an inspection lot shall be sampled in accordance with 7.2 and 7.3. 7.2 Analysis The sampling rate shall be in accordance with Table 19. 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. NOTE 1 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. NOTE 2 In cases of dispute concerning the results of analysis, the full procedure given in ISO 1811-2 should be followed. NOTE 3 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 quality system of the manufacturer is certified as conforming to EN ISO 9001. 7.3 Hardness and dezincification resistance tests The sampling rate shall be in accordance with Table 19. Sampling units shall be selected from the finished products. The test samples shall be cut from the sampling units and may require heat treatment before testing. 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 concerning the results of analysis, methods of analysis to be used shall be agreed between the disputing parties. For expression of results, the rounding rules given in 8.5 shall be used. SIST EN 12165:2011
EN 12165:2011 (E) 12 8.2 Hardness test 8.2.1 General When a hardness test is to be carried out the test samples shall be prepared in accordance with 8.2.2 and the test shall be carried out in accordance with 8.2.3. 8.2.2 Preparation of samples Test samples obtained in accordance with 7.3 shall be prepared directly from forging stock. 8.2.3 Procedure for testing Hardness shall be determined on test pieces cut from the test sample prepared in accordance with 8.2.2. The test shall be carried out in accordance with EN ISO 6506-1 and the impression/indentation made on the cross-section of the test piece mid-way between the central axis and the outside surface. NOTE When reporting hardness test results, reference should be made to the method of preparation of the sample (see 8.2.2). 8.3 Dezincification resistance test The test method given in EN ISO 6509 shall be used on the test samples obtained in accordance with 7.3. If required, the test samples shall be heat treated in the temperature range 450 °C to 550 °C before testing. 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; for sizes greater than 40 mm, the mean depth of dezincification (in accordance with Annex A) in a longitudinal direction shall also be measured. 8.4 Retests for analysis, hardness and dezincification resistance If there is a failure of one, or more than one, of the tests in 8.1, 8.2 or 8.3, 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. 8.5 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 Annex B of ISO 80000-1:2009. It shall be rounded in one step to the same number of figures used t

Foreword
This document (prEN 12165:2009) 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 12165:1998.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Pressure Equipment Directive
(PED) 97/23/EC.
For relationship with EU Directive 97/23/EC, see informative Annex ZA, which is an integral part of this
document.
Within its programme of work, Technical Committee CEN/TC 133 requested CEN/TC 133/WG 4 "Extruded and drawn
products, forging and scrap" to revise the following standard:
EN 12165, Copper and copper alloys — Forging stock
This 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
EN 12164, Copper and copper alloys — Rod for free machining purposes
EN 12166, Copper and copper alloys — Wire for general purposes
EN 12167, Copper and copper alloys — Profiles and rectangular bars for general purposes
EN 12168, Copper and copper alloys — Hollow rod for free machining purposes
EN 12420, Copper and copper alloys — Forgings
In comparison with the first edition of EN 12165:1998, the following significant technical changes were made:
a) some materials have been removed because they are no longer of economic importance;
b) the tables 8_to 16 of mechanical properties were rationalised to reflect current requirements of economic
importance.

6 Requirements
6.1 Composition
The composition shall conform to the requirements for the appropriate material given in Tables 1 to 8.
6.2 Mechanical properties
Shapes other than round can be delivered in M material condition in accordance between supplier and
customer.
The hardness properties of H. material condition material shall conform to the Brinell hardness requirements
given for forging stock with round cross-section in Tables 9 to 16. The test shall be carried out in accordance
with 8.3.
NOTE: In case mechanical properties are required for forging stock, rods in accordance with EN 12163 or EN 12164
shall be used.
6.3 Resistance to dezincification
The maximum depth of dezincification of CuZn36Pb2As (CW602N) products shall be 100 µm for sizes up to
40 mm. For greater sizes the average depth of dezincification shall be less than 100 µm and the maximum
measured value shall be less than 200 µm.
The test shall be carried out in accordance with 8.4.
NOTE The as-supplied forging stock may not necessarily meet this requirement unless suitably heat treated as
described in 8.4. The test is intended to demonstrate that forgings produced from the stock are capable of being
processed so as to pass the test requirement.
6.4 Dimensions and tolerances
6.4.1 Diameter
The diameter shall conform to the tolerances given in Table 17 for class A, B, as appropriate to the order [see

prEN 12165:2009 (E)
6.4.2 Deviation from circular form
For round rod the deviation from circular form shall not exceed half the range of the tolerance on diameter
given in Table 17.
6.4.3 Length
The forging stock shall have length and length tolerances agreed between customer and supplier.
6.4.4 Straightness
For round rod of diameter from 10 mm up to and including 50 mm of length 1 000 mm or over, the deviation
from straightness, defined as the curvature (depth of arc) against a datum line when the product is lying flat in
a horizontal plane, shall conform to the tolerances given in Table 18.
7 Sampling
7.1 General
When required (e.g. if necessary in accordance with specified procedures of a supplier’s quality system, or
when the purchaser requests inspection documents with test results, or for use in cases of dispute), an
inspection lot shall be sampled in accordance with 7.2 and 7.3.
7.2 Analysis
The sampling rate shall be in accordance with Table 20. 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.
NOTE 1 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.
NOTE 2 In cases of dispute concerning the results of analysis, the full procedure given in ISO 1811-2 should be followed.
NOTE 3 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 quality system of the manufacturer is certified as conforming to
EN ISO 9001.
7.3 Hardness and dezincification resistance tests
The sampling rate shall be in accordance with Table 20. Sampling units shall be selected from the finished
products. The test samples shall be cut from the sampling units and may require heat treatment before
testing. 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 concerning the results of analysis, methods of analysis to be used shall be
agreed between the disputing parties. For expression of results, the rounding rules given in 8.5 shall be used.

8.2 Hardness test
8.2.1 General
When a hardness test is to be carried out the test samples shall be prepared in accordance with 8.2.2 and the
test shall be carried out in accordance with 8.2.3.
8.2.2 Preparation of samples
Test samples obtained in accordance with 7.3 shall be prepared directly from forging stock.
8.2.3 Procedure for testing
Hardness shall be determined on test pieces cut from the test sample prepared in accordance with 8.2.2. The
test shall be carried out in accordance with EN ISO 6506-1 and the impression/indentation made on the cross-
section of the test piece mid-way between the central axis and the outside surface.
2
For the Brinell test in accordance with ISO 6506-1, a 0,102 F/D ratio of 10 shall be used i.e. use a 1,00 mm
diameter ball and a force of 98,07 N, or a 2,5 mm diameter ball and a force of 612,9 N, or a 10,0 mm diameter
ball and a force of 9 807 N.
NOTE When reporting hardness test results, reference should be made to the method of preparation of the sample
(see 8.2.2).
8.3 Dezincification resistance test
The test method given in EN ISO 6509 shall be used on the test samples obtained in accordance with 7.3. If
required, the test samples shall be heat treated in the temperature range 450 °C to 550 °C before testing.
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;
for sizes greater than 40 mm, the mean depth of dezincification (in accordance with Annex A) in a
longitudinal direction shall also be measured.
8.4 Retests for analysis, hardness and dezincification resistance
If there is a failure of one, or more than one, of the tests in 8.1, 8.2 or 8.3, 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.
8.5 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 Annex B of ISO 31-0:1992. It shall be rounded in one step to the same number of
figures used to express the specified limit in this standard.
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;
10
---------------------- Page: 12 ----------------------
oSIST prEN 12165:2009
prEN 12165:2009 (E)
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.
