Corrosion Testing Standards

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.

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.

ISO 6988:1985 specifies a method for assessing the resistance of materials or products to condensed moisture containing SO2. The method has been found to be suitable for testing metallic and non-organic coatings. Gives apparatus and material, test specimens, methods of exposure, procedure, test duration, cleaning of specimens, evaluation of results and test report.
