适用范围：The document describes the areas of use for the outer corrosion protection of buried pipes made of ductile cast iron according to DIN 28600 and DIN 19690. The document can also be applied for pipes in water accordingly. As far as no hightened mechanical loads and no electro-mechanical influences occur, the corrosion-chemical load can be classified in earth quality (category I). Danger through corrosion exists when electro-chemical influences occur (building of element) and also in the water-air-area. Please see the explanations under DIN 50929 part 3 regarding the judgement of the danger through corrosion as well as necessary protecting means.#,,#
