EVS-EN 13052-1:2001

This standard specifies a method for determining the colour and turbidity of test waters after their contact with the internal surfaces of products made from organic materials used in piping systems, where the term 'products' comprises pipes, fittings, ancillaries and their coatings and joints.
The test method described in this standard is applicable to products to be used under various conditions for the transport of water intended for human consumption and raw water used for the manufacture of water intended for human consumption. Coatings or protective layers on products which are not intended to be in contact with these types of water are not covered by this method.
