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 and 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 6270-2 (AT)

Procedure for exposing test specimens in condensation-water atmospheres.

This test standard replaces and is similar to DIN 50 017*.

Test ‘AT’ (condensation atmosphere with alternating temperature only) – requires 40°C reducing to 18-28°C, while maintaining a condensation humidity level of c.100%RH.

* The correlation between the above 6270-2 test method and the DIN 50 017 test methods, is:
6270-2 method ‘AT’ is equivalent to DIN 50 017 method ‘KTW’.
