The lead release from the bulk material is not affected by the lead film on the surface and depends on the composition of the material. The bulk material can release lead for a long period (long term behaviour). It is possible to test materials for their lead release from the bulk material (EN 15664-1 and -2), so that products made of approved materials do not have to be tested for this characteristic. As the lead films on the surface depend on the individual manufacturing process, it is necessary to test the products or the manufacturing process. This test method is intended to be used as a process control method to assess the presence of lead films on the inner surface of products intended to come in contact with drinking water or to assess the efficiency of a manufacturing process to remove or minimise surface Pb, e.g. washing process to remove lead on surfaces. The implementation of an audit controlled process monitoring is an effective w
