DIN 50018-2013适用范围

This standard mainly covers performance checks carried out on test arrangements used to assess anti-corrosion systems. Users of this standard are also requested to consult other relevant standards and regulations and are advised that individual test conditions may be also agreed upon on a case by case basis. As it cannot be ruled out that specimens, on which different anti-corrosion systems have been applied, may interact, it is recommended that different anti-corrosion systems be tested separately. If various anti-corrosion systems applied to different test materials are to be tested together, it should be taken into account that the sulfur dioxide tends to have diverse effects on the materials under test and that results are, therefore, not always reproducible. Unless the anti-corrosion systems compared are similar to one another, it may be difficult to draw reliable conclusions with regard to their effectiveness under service conditions. In the same way that corrosive test conditions differ considerably from those occurring in service, so do the levels of protection afforded by anti-corrosion systems.

本标准主要涵盖对用于评估防腐系统的试验安排进行的性能检查。本标准的使用者还应参考其他相关标准和法规，并建议根据具体情况商定单独的试验条件。由于不能排除已应用不同防腐系统的试样可能相互作用，因此建议单独测试不同的防腐系统。如果对不同试验材料使用的各种防腐系统要一起进行试验，则应考虑到二氧化硫往往对试验材料产生不同的影响，因此，结果并不总是可再现的。除非所比较的防腐系统彼此相似，否则可能难以就其在使用条件下的有效性得出可靠结论。腐蚀性试验条件与使用中的腐蚀性试验条件有很大不同，同样，防腐系统提供的防护等级也有很大差异。
