Example applications for acetic acid salt spray tests

acidic salt spray tests for surfaces

Salt spray tests are frequently used in the field of surfaces to test coatings. Such a test can be carried out, for example, to determine or compare the adhesion of a coating. To do this, samples are visually assessed at defined time periods and, for example, pitting corrosion or crevice corrosion is recorded and documented.

Acidic salt spray tests for technical safety

The safety of components depends to a large extent on their area of application. That is why test specimens are exposed to corrosive media in time-lapse tests to provoke corrosion attacks. In particular, metallic components that are exposed to the environment should be tested using salt spray tests as part of technical safety.
