    Corrosion in potable water varies greatly depending upon the water composition. The most important factors are oxygen content, pH value, temporary hardness, chloride, sulfate, and conductivity. To be able to carry out tests of corrosion resistance, thorough knowledge of corrosion processes of the individual metals and alloys in supply water is required. This is important in order to identify the most deleterious combinations of the relevant factors. Testing must take place as a combination of field tests and laboratory tests. Not only methods for testing materials are required in the efforts to prevent corrosion but also methods for testing water types. The actual corrosion also depends on design and performance of the individual parts and the complete pipe system. Where it is not possible to control the corrosion, easy replacement of the pipes must be ensured. An account is given of corrosion and corrosion testing of the commonly used materials galvanized steel, copper, and brass and of soldering metals, also in relation to metal pickup. This paper reviews the use of test methods to control different corrosion types in tap water systems and describes recent developments in this field at the Danish Corrosion Centre.
