The test standard summaries are for general guidance only. Though believed to be accurate at the time of writing, this may change over time. So this information should not be used as a substitute for referring to a complete test standard, at an appropriate revision level.
Note: the terms salt spray, salt mist & salt fog are all in wide spread use within corrosion test standards. In this context they can be considered to be equivalent and interchangeable terms.
UNI EN ISO 6988
Kesternich testing simulates acid rain or industrial chemical exposure to evaluate the relative corrosion resistance of the coating, substrate, or part itself. Parts or panels are placed inside a specially designed chamber and are exposed to SO2 and humidity before being evaluated for resistance to corrosion. The following standard used in this type of test.
UNI EN ISO 6988 Test Standard is used for Metal coatings and other non-organic coatings. The standard specifies a method for assessing the corrosion resistance of materials or products to an atmosphere containing condensed moisture and sulphur dioxide. The method was found suitable for evaluating metallic coatings and other non-organic coatings.
