Scope
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.
Purpose
Modification of the limits of certain alloys cited in the Standard, Addition of some new alloys; Removal of some leaded alloys according to the Roadmap of the European brass rod industry for the reduction of the use of Pb in brass alloys in a series of steps.
