Environmental testing
Environmental testing helps to ensure the durability and performance of products and materials under different operating and environmental conditions.
Accelerated and natural ageing
Testing of materials for weathering
We use environmental chambers with a test temperature range of -40….+180 °C, with a relative humidity control range of 10….98 %. We investigate the effect of light on materials by UV and xenon light testing.
At the Mikkeli campus, we also carry out standardised long-term natural ageing test cycles outdoors. At the environmental field we have continuous monitoring of conditions, including UV radiation, temperature, relative humidity and precipitation. For UV measurement we use high quality measuring equipment from Kipp & Zone. We monitor weather conditions with a Vaisala NM10 weather station.
To test the corrosion resistance of materials, we have a salt spray cabinet with continuous salt spray and the possibility of cyclic corrosion tests.
In addition, we have xenon and UV condition test equipment which, in addition to the radiation output, can adjust the temperature, humidification and precipitation either cyclically or continuously. If required, we can build UV stress test equipment to meet customer requirements.
The condition chambers can also be used for combined tests, where specimens are moved from one condition chamber to another.
