Alternating corrosion test chamber

Alternating corrosion test chambers play a crucial role in the testing of coatings designed to protect materials against corrosive influences. They simulate changing environmental conditions, such as temperature cycles, high humidity, salt spray and dry phases, to evaluate the resistance and effectiveness of coatings.

Coatings that are applied to metals, plastics or other materials are used to protect surfaces from harmful influences such as oxidation, chemical attacks or mechanical wear. In a corrosion change test chamber, they are tested under realistic and accelerated conditions to determine whether they retain their protective effect in the long term.

The tests often include a combination of corrosion and ageing influences that can be adapted for specific applications. In this way, weak points in the coating or at transition points between the coating and the material can be identified at an early stage. The results of these tests are crucial for the development and optimization of coatings, particularly in industries such as the automotive, construction and aviation sectors.

The use of such test chambers in accordance with international standards such as ISO 12944 or ASTM B117 ensures that the tested coatings meet the required quality standards and offer reliable protection over the entire service life of a product.
