Corrosion tests in artificial atmospheres - Salt spray tests

Demands on coating systems are constantly increasing. The resistance of components to corrosion is a key indicator of the quality of an electrochemical coating. Any defects in the substrate or metallic coating will be incorporated in the coating. The salt spray test serves as an inspection of resistance to corrosion.

Salt spray testing

We analyse reliably and safely using state-of-the-art equipment backed up by many years' experience.

We have at our disposal several test chambers with examination volumes of 400 l to 2000 l for salt spray tests in accordance with DIN EN ISO 9227 NSS / AASS / CASS (which replaced DIN 50021 SS / ESS / CASS) and ASTM B 117.

Salt spray testing

The base frames of the chambers have been reinforced to enable us to test even heavy specimens.

Our 2000 l chamber is large enough to accommodate components with a length of up to three metres.

In our analysis reports, we document not only the results of the tests but also interim observations as the test progresses.

Salt spray testing by analogy to DIN EN ISO 9227 with modified parameters (e.g. temperature; concentration; type of salt such as road-gritting salt (NaCl + CaCl2 (calcium chloride)).
