标准范围

IEC 60068-2-11:20 21规定了评估电工产品部件、设备和材料在盐雾环境中耐腐蚀性的测试方法。其目的是验证金属材料（无论有无腐蚀保护）在暴露于盐雾时是否能保持相对质量。该测试方法可用于评估用于保护金属免受腐蚀的涂层的质量和均匀性。它特别适用于检测某些金属、有机、阳极氧化物和转化涂层中的不连续性，如孔隙和其他缺陷。第四版取消并取代了1981年出版的第三版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)盐溶液的制备已被修改；b)改变了用于测量pH的溶液的温度；c)饱和塔的雾化压力和水温已加入，见表1；d)测试报告细节已被修改；e)附录A中增加了典型测试设备的示例并给出；f)增加了评估设备腐蚀性的方法，并在附录B中给出；g)增加了参考书目。

IEC 60068-2-11:2021 specifies a test method for assessing the corrosion resistance of electrotechnical products components, equipment and materials in a salt mist environment. Its objective is to verify that the comparative quality of a metallic material, with or without corrosion protection, is maintained when exposed to salt mist.
This test method is useful for evaluating the quality and the uniformity of coatings applied to protect metals against corrosion. It is particularly useful for detecting discontinuities, such as pores and other defects, in certain metallic, organic, anodic oxide and conversion coatings.
This fourth edition cancels and replaces the third edition published in 1981. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) the preparation of the salt solution has been modified;
b) the temperature of the solution for measuring pH has been modified;
c) the atomizing pressure and water temperature of the saturation tower have been added and are given in Table 1;
d) test report details have been modified;
e) examples of typical test apparatus have been added and are given in Annex A;
f) a method for evaluating corrosivity of the apparatus has been added and is given in Annex B;
g) a bibliography has been added.
