DIN 50929-3-1985 金属腐蚀.承受外部腐蚀时金属材料腐蚀的概率.掩埋的和水中的管道和结构零组件构件
Corrosion of metals; probability of corrosion of metallic materials when subject to corrosion from the outside; buried and underwater pipelines and structural components
The definitions described in this standard indicate the rating of the corrosion probability of metallic pipe lines, containers and components of which surfaces are exposed to soil and surface water. The corrosion probability of these parts is not defined by the characteristics of the material and corrosive media, but by the type of construction and its spatial extension as far as other variables. As the variables cannot be described suffiently, only probability statements of the expected corrosion are possible. These statement should inform in which kind and in which dimension corrosion occurs and which protective measures are useful or absolutely necessary.#,,#
