DIN EN 12164:2016-11

DIN EN 12164:2016-11 is one of a series of European Standards for the copper and copper alloy products rod, wire, profile and forgings that have been updated simultaneously. The other standards are:

• EN 12163, Copper and copper alloys – Rod for general purposes;
• EN 12165, Copper and copper alloys – Wrought and unwrought forging stock;
• EN 12166, Copper and copper alloys – Wire for general purposes;
• EN 12167, Copper and copper alloys – Profiles and bars for general purposes;
• EN 12168, Copper and copper alloys – Hollow rod for free machining purposes.

In comparison with the previous edition from 2011, a number of technical changes have been made, the most important being the addition of four new materials (CuZn37Pb1 (CW605N), CuZn35Pb1,5AlAs (CW625N), CuZn33Pb1,5AlAs (CW626N) and CuZn33Pb1AlSiAs (CW725R)) and modification of the chemical composition of CuZn39Pb1 (CW611N) to take into account more stringent requirements regarding

• lead content,
• the introduction of an optional procedure for referring to restrictions to the chemical composition imposed by the 4 MS Common Composition List for materials used for products permitted for contact with drinking water,
• the modification of requirements and test methods for resistance of dezincification, the addition of provisions for surface quality,
• and the modification of the mechanical properties for CuZn21Si3P (CW724R).
