Introduction
This European Standard for copper alloy ingots, and copper and copper alloy castings is based on
previous national standards and harmonizes the compositions and mechanical properties required.
This European Standard does not include copper refinery shapes which are intended for working into
wrought products and are the subject of EN 1976. Nor does it include master alloys intended for the
manufacture of copper alloys which are the subject of EN 1981.
The essential information relevant to correct ordering, given in Clause 5 of the standard, is
supplemented by Annex A, which is based upon the recommended practice for the ordering and supply
of castings given in EN 1559-1. Its purpose is to assist the purchaser in providing full information to the
supplier to ensure that he supplies castings according to the purchaser's requirements. It is
recommended that full consultation takes place between the purchaser and the supplier at the stages of
enquiry and ordering.
Sampling and testing frequency, where applicable, are specified in Clause 7. For certain applications,
more rigorous inspection procedures may be required. Annex B gives supplementary inspection
procedures which may be invoked, at the option of the purchaser [see Clause 5 o)].
Some copper and copper alloys can be used in castings for pressure equipment. Ingots are not suitable
for pressure equipment.
The permitted material grades of copper and copper alloys for pressure applications and the conditions
for their use are given in specific product or application standards.
Information on permissible alloys in drinking water installations is given in the relevant tables in the
appendix in accordance with the applicable European requirements at the time the standard was
published.
For the design of pressure equipment, specific design rules apply.
Annex ZA gives information relating to the conformance of permitted material grades of copper and
copper alloys used in castings to the New Approach Pressure Equipment Directive 2014/68/EU.
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 alloy CuZn21Si3P-B
(CB768S) and CuZn21Si3P-C (CC768S) given in Table H.2 as well as concerning the alloy CuSn12S-B
(CB472K) and CuSn12S-C (CC472K) given in Table J.6 as well as concerning the alloy CuSi4Zn4MnP-B
(CB245E) and CuSi4Zn4MnP-C (CC245E) given in Table Q.1 as well as concerning the alloy
CuSi4Zn9MnP-B (CB246E) and CuSi4Zn9MnP-C (CC246E) given in Table Q.2 as well as concerning the
alloy CuSn4Zn2PS B (CB470K) and CuSn4Zn2PS C (CC470K) given in Table L.1 as well as concerning the
alloy CuSn7Zn3Ni2PS-B (CB471K) and CuSn7Zn3Ni2PS-C (CC471K) given in Table L.2.
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

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 specified in this European Standard may be
restricted to the composition 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.
