This European Standard specifies a procedure to determine the release of metals from metallic materials used in construction products intended to come into contact with drinking water .
The test can be used for three purposes:
a) Assess a material as a reference material for a category of materials using the results of several investigations in different waters covering a broad range of water compositions.
b) Assess a material for approval by way of comparative testing.
c) Obtain data on the interaction of local water with a material.
