Copper and copper alloys - Ingots and castings
This document specifies the composition, mechanical properties and other relevant characteristics of copper and copper alloys. The sampling procedures and test methods for the verification of conformity to the requirements of this document are also specified.
This document is applicable to:
a) copper alloy ingots intended to be remelted for later processing (e.g. castings); and
b) copper and copper alloy castings which are intended for use without subsequent working other than machining.
Recommended practice for the ordering and supply of castings is included in Annex A. Optional supplementary inspection procedures for ingots and castings are included in Annex B.
NOTE Ingots are not suitable for pressure equipment applications.
Kupfer und Kupferlegierungen - Blockmetalle und Gussstücke
Dieses Dokument legt die Zusammensetzung, die mechanischen Eigenschaften und andere wichtige Werkstoffeigenschaften für Kupfer und Kupferlegierungen fest. Der Ablauf der Probenahme und die Prüfverfahren zur Feststellung der Übereinstimmung mit den Anforderungen dieses Dokuments sind ebenfalls festgelegt.
Dieses Dokument ist anwendbar auf:
a) Blockmetalle aus Kupferlegierungen, die für eine spätere Verarbeitung (z. B. zu Gussstücken) für eine Umschmelzung vorgesehen sind; und
b) Gussstücke aus Kupfer und Kupferlegierungen, die für den Gebrauch ohne nachfolgende Bearbeitung, ausgenommen die mechanische Bearbeitung, bestimmt sind.
Eine empfohlene Verfahrensweise für die Bestellung und Lieferung von Gussstücken ist in Anhang A enthalten. Wahlfreie ergänzende Prüfverfahren für Blockmetalle und Gussstücke sind in Anhang B enthalten.
ANMERKUNG Blockmetalle sind für Druckgeräteanwendungen nicht geeignet.
Cuivre et alliages de cuivre - Lingots et pièces moulées
Le présent document spécifie la composition, les propriétés mécaniques et autres caractéristiques appropriées du cuivre et des alliages du cuivre. Les procédures d’échantillonnage et les méthodes d’essai pour la vérification de la conformité aux exigences du présent document sont également spécifiées.
Le présent document s’applique aux :
a) lingots en alliages de cuivre destinés à être refondus en vue d’une transformation ultérieure (par exemple pièces moulées) ; et
b) pièces moulées en cuivre et alliages de cuivre destinées à être utilisées sans transformation ultérieure autre que l’usinage.
L’Annexe A donne les pratiques recommandées pour la commande et la fourniture de pièces moulées. L’Annexe B donne les procédures de contrôle supplémentaires optionnelles pour les lingots et pièces moulées.
NOTE Les lingots ne sont pas adaptés aux applications dans les équipements sous pression.

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 133.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.
This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and
