Climate, exposure and weathering test

Environmental simulations play a significant role for outdoor product groups.  Exposure and weathering tests as well as climate tests can be carried out at TITK.

Exposure and weathering test

Exposure and weathering testing offers the possibility to expose samples to temperature changes, humidity and irradiation. This allows a practical environmental simulation to be generated.

This test provides information about the change in physical and chemical properties of components under different weather conditions (e.g. heat and cold, rain, UV radiation).

The following measuring device is available:

  • Exposure and weathering tester Xenotest 440 (Atlas MTS)
  • 2 x 2200 W air-cooled xenon lamps
  • 2310 cm² exposure area
  • Adjustment and control of irradiance, black standard temperature, relative humidity, chamber air temperature
  • Temperature range: 10 °C to 115 °C
  • Humidity range: 10 %rh to 75 %rh
  • Sample spray systems (60 l water reservoir deionised)
  • Rotating sample carousel with 38 test positions (13.5 cm x 4.5 cm); 33 (10.0 cm × 6.8 cm); 22 (13.5 cm × 5.5 cm); 11 (29.5 cm x 7.0 cm)
  • Pre-programmed lightfastness and weathering standards

Climate tests

The TITK has the possibility to carry out climatic tests under variation of humidity and temperature.


  • VC4020 (Vötsch)
  • Temperature range: -40 °C to 180 °C
  • Temperature gradient: 4 Kmin
  • Humidity range: 10 %rh to 98 %rh
  • Samples can be supplied with voltage if required
  • Simultaneous optical, electrical or mechanical testing
  • Testing according to DIN 60068-2-1 as well as individual customer standards
