This document specifies a procedure to determine the release of metals from metallic materials used in products intended to come into contact with drinking water . The test can be used for three purposes: a) To assess a material as a reference material for a new category of materials by metal release testing using the results of several investigations in different waters covering a broad range of water compositions. b) To assess a material for an existing category for approval by way of metal release testing using the water defined in part 2, which exhibited the highest metal release when the reference material of the category was tested. c) To obtain data on the interaction of local water with a material.
