国际标准化组织 11997-1-2017 – 色漆和清漆耐循环腐蚀性能的测定 第一部分 1: 湿的 (盐雾)/ 干湿

The third edition cancels and replaces the second edition of the technical revision (国际标准化组织 11997-1:2005).

Compared with the previous edition, the main changes are as follows:

– The time when no moisture can be seen on the panel (看 6.4) 已经变了;

– Added reference to ISO 4628-8 for assessing the degree of delamination and corrosion around markings or other man-made defects;

– Added reference to ISO 4620-10 for assessing the degree of filamentous corrosion;

— Supplementary test conditions previously listed in Annex A have been incorporated into the test report;

— The number and order of attachments have been changed;

– The pH adjustment procedures for salt solutions in Appendices A to D have been implemented since ISO 9227;

– Where possible, the text has been aligned with the new version of ISO 9227.

国际标准化组织 11997-1-2017 – 色漆和清漆耐循环腐蚀性能的测定 第一部分 1: 湿的 (盐雾)/ 干湿

介绍
油漆, varices and coatings of similar materials are exposed to one of the four cycles of wet and dry conditions specified in this document (see Annex A of Annex D) using the specified salt solution in the cabinet in order to simulate in the laboratory the processes that occur under corrosive outdoor conditions, such as Marine environments. 一般来说, a correlation between such outdoor aging and laboratory tests cannot be expected due to the large number of factors affecting the breakdown process. Correlations can only be expected if the effects of important parameters, such as the nature of the contaminant, the spectral distribution of incident irradiance in the relevant photochemical region, the temperature of the specimen, the type and period of wetting, and the relative humidity, on the coating are known. Compared to outdoor aging, the number of variables that can be controlled is smaller when laboratory testing is performed in a cabinet, so the effect is more reproducible. The described method can also provide a means of checking whether the quality of the paint or paint system is maintained.

It has been found that this method can be used to compare the cyclic salt spray tolerance of different coatings. It is most applicable to provide relevant ratings for a range of coated panels that exhibit significant differences in cyclic salt spray resistance.

The test cycles included in this document have been successfully used in the industry for performance evaluation with documented evidence. The cycle can be summarized as follows.

— Cycle A (见附件A) : This cycle is specified in the Japanese automotive standards JASO M 609-91 and JASO M610-92.

— Cycle B (see Annex B) : This is based on the VDA 621-415 循环, which is widely used in Europe. It has also been shown to correlate well with the natural weathering of thermoset coatings in vehicle corrosion.

-Cycle C (see Annex C) : This cycle was developed in the UK for use in water-soluble and latex paint systems and has been shown to correlate well with natural weathering.

— Cycle D (see Annex D) : This cycle is specified in the Japanese standard JIS K 5621-2003.

Additional loops are intended to be added in subsequent revisions of this document, as they were developed for the evaluation of other paint types.

国际标准化组织 11997-2 describes a method for determining paint cycle corrosion resistance that includes UV exposure as part of the cycle. It has been found to have a good correlation with the natural weathering of industrial maintenance coatings.
