What is this standard about?
This European standard specifies the composition, property requirements and dimensional tolerances for copper alloy rods. These take the shape of circles, squares, hexagons or octagons, finally produced by drawing or extruding and intended for general purposes.
Who is this standard for?
- Manufacturers of copper and copper alloys
- Suppliers of copper, copper alloys and wrought alloys
- Regulatory bodies
- Inspectors
This series is important to a wide variety of industries including general engineering, oil and gas, marine, defence, aerospace and electrical.
Why should you use this standard?
It outlines all the requirements for the right composition and mechanical properties of materials. The standard explains the resistance to dezincification, as well as the dimensions and various tolerances – including form tolerances. It also defines diameter, length and straightness. The sampling procedures and the methods of test for verification of conformity to the requirements of this European standard are also specified.
What’s changed since the last update?
Significant technical changes include:
- Introduction of an optional procedure on how to refer to restrictions to the chemical composition imposed by the 4 MS Common Composition List. This outlines materials used for products accepted for contact with drinking water
- The requirements and test methods for resistance of dezincification are modified
- Provisions for surface quality are added
- Mechanical properties for CuZn21Si3P (CW724R) are modified
