Copper and copper alloys - Profiles and bars for general purposes

This European Standard specifies the composition, property requirements and dimensional tolerances for copper alloy profiles including L-, T-, U-shaped cross-sections, and bars, finally produced by drawing or extruding.
This European Standard applies to profiles with L-, T- and U-shaped cross-sections which would fit within a circumscribing circle of a maximum 180 mm diameter and to bars with thicknesses from 3 mm up to and including 60 mm and with widths from 6 mm up to and including 120 mm.
The sampling procedures, the methods of test for verification of conformity to the requirements of this European Standard, are also specified.

Kupfer und Kupferlegierungen - Profile und Rechteckstangen zur allgemeinen Verwendung

Dieses Dokument legt die Zusammensetzung, die Anforderungen an die Eigenschaften und die Grenzabmaße für durch Ziehen oder Pressen endgefertigte Profile, einschließlich Profilen mit L-, T- und U-förmigen Quer
schnitten und Rechteckstangen aus Kupferlegierungen fest.
Dieses Dokument gilt für Profile mit L-, T- und U-förmigen Querschnitten mit einem Durchmesser des umschreibenden Kreises von höchstens 180mm und Rechteckstangen mit Dicken von 3mm bis 60mm und Breiten von 6mm bis 120mm.
Der Ablauf der Probenahme und die Prüfverfahren zur Feststellung der Übereinstimmung mit den Anforde
rungen dieses Dokuments sind ebenfalls festgelegt.

a) Introduction of 6.7 Internal inclusion;
b) Added a new Figure for straightness at and modified values in Table 21;
c) Introduction in the chemical composition Tables of a footnote to explain the meaning of elements for
which no upper and lower limits are defined;
d) CuZn4Si4MnP (CW245E) and CuZn9Si4MnP (CW246E) added in the new Table 2 and new Table 10
e) Chemical composition of CuZn39Pb3 (CW614N), CuZn40Pb2 (CW617N), CuZn35Pb1,5AlAs
(CW625N) and CuZn33Pb1,5AlAs (CW626N) modified in the new Table 7;
f) Added a new alloy CuZn40Pb1 (CW627N) in the new Table 7 and Table 15;
g) Chemical composition of CuZn33Pb1AlSiAs (CW725R) modified in the new Table 8;
