Laboratory of Corrosion Engineering

The laboratory of corrosion and climatic tests offers high-end technical equipment for performing of corrosion tests as Copper Accelerated Salt Spray Test or Acetic Acid Salt Spray Test, neutral Salt Spray Test together with climate control, condensation tests, temperature change tests and climate tests with the possibility of additional loading of samples with IR and UV radiation or simultaneous measurement of selected product parameters (eg electrical quantities).

The laboratory also performs microscopic determination of the number of micropores / microcracks of Cr coatings and determination of layer and multilayer thicknesses on metallic and non-metallic substrates either microscopically or non-destructively using X-ray fluorescence.

More detailed information on test equipment is given in the "Technical specifications" tab, the range of tests performed according to individual standards can be found under the "Tests" tab.
