Brass Alloys For Drinking Water Applications

To protect the quality of healthy drinking water,the materials which in contact with drinking water installations have restricted in EU counties and in the USA. Based on 4MS Initiative supported by Germany,France, Netherlands, the United Kingdom and Denmark metallic materials used for products in contact with drinking water are specified. We offer our customers for different kind of drinking water brass alloys according to 4MS common composition list.

Product Group Examples of products or parts of products Assumed contact surface ‘a’
A Pipes in buildings installation Uncoated pipelines in water supply systems 100%
B Fittings, ancillaries in buildings installations (e.g pump bodies, valve bodies, watermeter bodies used in building installations.) 10%
C 1- Components of products of product group B (e.g. the spindle of a pump or the moving parts in water meter in building installations). The sum of the surfaces in contact with drinking water of all these components has to be less than 10% of the total wetted surface of the product.
2- Fittings, ancillaries in water mains and water treatment works with permanent flow (e.g. pumps bodies, valves bodies used in water supply systems).
1%
D Components of fittings and ancillaries in water mains and in water treatment works (C2).
