Central test laboratory

Corrosion / weathering tests

• Salt spray test according to DIN EN ISO 9227

            1 corrosion test chamber for neutral salt spray (NSS)

            1 corrosion test chamber for acetic acid salt spray (AASS)

• Continuous condensation according to DIN EN ISO 6270

Wet chemical quality testing for environmental simulation. Natural environmental influences that have a negative effect on metallic and non-metallic coatings are accelerated by artificial weathering. In this way, a statement can be made about the corrosion behavior over a short period of time.

Testing of surfaces / coatings

• Color measurements according to DIN EN ISO 11644-4
• Gloss level (reflectometer value) according to DIN EN ISO 2813
• Coating thickness according to DIN EN ISO 2178 or DIN EN ISO 2360
• Adhesion: Cross cut according to DIN EN ISO 2409, pull-off test according to DIN EN ISO 4624
• Elasticity: Mandrel bending according to DIN EN ISO 1519, Erich indentation according to DIN EN ISO 1520, ball impact according to DIN EN ISO 6272-1 and ASTM D 2794
• Buchholz hardness according to DIN EN ISO 2815
• Roughness determination according to DIN EN ISO 9013 and DIN EN ISO 4288

Variable methods for physical and optical surface classification with focus on non-destructive testing.

Metal analysis

• Versatile for qualitative and quantitative elemental determination in metals and alloys
• OES analysis (Optical Emission Spectroscopy)
• Automated method
• Non-destructive, as the test object can often be reused despite the focal spot

The basic principle is the vaporization of the material by an electric arc. The resulting spectrum is analyzed in terms of wavelengths and intensities. Characteristic values of individual elements allow conclusions to be drawn about their quantitative distribution in the material.

Dimensional accuracy testing

• Digital measuring projector (e.g. for profiles, maximum measurement size 300x200 mm)
• Conventional measuring instruments (e.g. micrometers, calipers, etc.)
• Flatness tests on granite measuring table 2.0 x 1.0m
