Salt Mist Corrosion Test Judgment Standard and Methods -qinsun

The purpose of the salt fog test is to assess the salt -resistant corrosion quality of the product or metal material, and the judgment of the salt fog test results is the judgment of the product quality. Whether it is correct and reasonable is the key to correctly measure the quality of products or metal antibody fog corrosion. The method of judging the results of the salt fog test results include: rating judgment, weighing judgment method, corrosion judgment method, and corrosion test data statistical analysis method.

Rating judgment method: It is to divide the percentage of the ratio of corrosive rust area to the total area of the total area into several levels according to a certain method.

Weight judgment method: It is a method of weighing the weight of the sample before and after the corrosion test, and the weight of the corrosion loss is calculated to judge the corrosion resistance of the sample. Evaluation of corrosion quality;


Corrosion judgment method: It is a qualitative judgment method. After the salt and mist corrosion test, whether the product produces corrosion This method;


Corrosion data statistical analysis method: provides a method of designing corrosion tests, analyzing corrosion data, and determining corrosion data. The quality judgment of a specific product.
