6 Requirements
6.1 Composition
The composition shall conform to the requirements for the appropriate material given in Tables 1 to 6.
Due to developing legislation, specific applications (see 4.3) may require restrictions in the chemical
composition. In this case the limitations shall be specified in the ordering information [see Clause 5 list
entry f)].
6.2 Mechanical properties
The tensile properties of R. material condition or the hardness properties of H. material condition shall
conform to the appropriate requirements given in Tables 7 to 12. The tests shall be carried out in
accordance with 8.2 or 8.3.
6.3 Grain size
The grain size of G. material condition shall conform to the appropriate ranges in Table 13. The tests
shall be carried out in accordance with 8.4.
6.4 Dimensions and tolerances
6.4.1 Diameter or width across-flats
Diameter or width across-flats at any point shall conform to the tolerances given in Tables 14 to 16.
6.4.2 Shape tolerances
6.4.2.1 Round wire
The deviation from circular form (see 3.2) of round wire less than 3,0 mm diameter, shall not exceed half
the range of the tolerance on diameter given in Table 14. The deviation from circular form of round wire
equal to or greater than 3,0 mm diameter, shall not exceed the range of the tolerance on diameter given
in Table 14.
6.4.2.2 Wire with square or regular cross-section (see above)
The width across-flats, measured at the centre of the faces at any one cross-section, shall not differ by
more than half the range of the tolerance given for the size in Table 15.
6.4.3 Corner and edge geometry (wire with square and rectangular cross-section only)
The radii of the corners of wires shall conform to the requirements given in Table 17 for sharp or rounded
corners.
For wires with the minimum width across-flats less than 3 mm the corners shall be calculated according
to Figure 1. For wires with both widths across-flats equal to or greater than 3 mm, except in cases of
dispute, the corners shall be measured directly, either by use of a gauge or an optical projector. In cases
of dispute the method by optical projector shall be used.
Wire edges shall be smooth along the product length without discontinuity.
For sizes below 3 mm, the corner radius c is calculated from the
formula:
cc+
c=
and may fall anywhere between fully circular 'a' and a chamfer 'b'.
Figure 1 — Calculation of corner radii
6.5 Joins
Welds made before the final drawing sequence are permissible. Joins made after the final drawing
sequence are not permitted unless there has been agreement between the involved parties on the method
of performing and marking these joins.
6.6 Surface quality
The surfaces shall be clean and smooth. The wires may have a superficial film of drawing lubricant or, if
annealed or thermally stress relieved, a superficial, dull, iridescent oxide film, securely adherent on the
surfaces.
Discontinuous irregularities on the surfaces of the wires are permitted if they are within the dimensional
tolerances.
Since surface discontinuities (cracks, overlapping, scale, isolated pores, pits, grooves, etc.) cannot be
completely avoided during manufacturing (hot and cold formation, heat treatments, handling and
storage) and since they are retained when drawing, agreements shall be made regarding surface quality.
If eddy current test is requested, the test method given in EN 17263:2019 shall be applied using reference
standard according to Table 19 for round wire. For polygonal wire the reference standard shall be agreed
between the involved parties.
The sensitivity is to be set in such a way that the smallest signal of the borehole(s) just exceeds the
response threshold (acceptance level).
Special requirements (e.g. pickling, degreasing, etc.) relating to the surface quality shall be agreed
between the involved parties [see Clause 5, list entry n)].
6.7 Internal inclusion
Freedom of internal inclusions cannot be ensured in any copper alloys.
7 Sampling
7.1 General
When required 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 18. 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 assure the traceability of
the product.
7.3 Tensile, hardness and grain size tests
The sampling rate shall be in accordance with Table 18. 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.
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 8.6 shall be used.
8.2 Tensile test
The tensile test shall be performed on a coaxial test piece cut from a test sample obtained in accordance
with 7.3. The test shall be carried out in accordance with the method given in EN ISO 6892-1:2019. For
expression of results, the rounding rules given in 8.6 shall be used.
For other than round wire, the tensile test results shall be calculated using nominal cross-sectional areas.
Elongation requirements for wire of diameter:
a) less than 4 mm (A );
100 mm
b) 4 mm up to and including 8 mm (A );
11,3
c) greater than 8 mm (A);
are based on original gauge lengths of 100 mm, 11,3 S mm and 5,65 S mm respectively, where S
o
o o
is the original cross-sectional area of the test piece in square millimetres.
Elongation values are not applicable to wire sizes less than 0,5 mm (or equivalent cross- sectional areas
for polygonal wires).
8.3 Hardness test
Hardness shall be determined on test pieces cut from a test sample obtained in accordance with 7.3. The
test shall be carried out in accordance with EN ISO 6507-1:2018 and the indentation made:
a) for round wire 5 mm diameter and over, at a mid-radius position on a cross-section (see 2nd
paragraph below);
b) for rectangular cross-sections, on the surface of the wire at the approximate mid-point of the major
dimension;
c) for square or polygonal cross-sections, on the surface of the wire at the approximate mid-point of
one of the flats;
d) for profiles, unless otherwise specified at the time of the order, on the cross-section at the mid-point
of the thickest part.
In the case of round wire less than 5 mm diameter, the test shall be performed at a position, and by a
method, agreed between the involved parties.
For the Vickers test according to EN ISO 6507-1:2018 it is required to use a test force of 49,03 N, 98,07 N
or 294,21 N.
8.4 Estimation of average grain size
When at the time of order a grain size requirement is specified [see Clause 5 list entry e)], the estimation
of average grain size shall be carried out in accordance with EN ISO 2624:1995.
8.5 Retests
If there is a failure of one, or more than one, of the tests in 8.1, 8.2, 8.3 or 8.4, 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 document. If a test piece fails a test,
the inspection lot represented shall be deemed not to conform to this document.
8.6 Rounding of results
For the purpose of determining conformity to the limits specified in this document 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
)
2 1
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 m)] the appropriate certificate
of compliance shall be issued for the products.
NOTE The relevant information is available in EN ISO/IEC 17050-1:2010 and EN ISO/IEC 17050-2:2004.
