Climate Testing: spray test

The spray test is used to describe the effectiveness of corrosion protection systems and analyse metallic coatings for defects.

An aqueous sodium chloride solution is atomised continuously in the chamber. This test method is simply designed to induce rapid corrosion and does not permit direct statements about the behaviour of the tested part when used in the field. The exposure to corrosion can deviate substantially from the conditions prevailing in practice, which is why this test is mainly suitable for comparing different systems.
