Environmental simulations


The aging of components plays an important role in sustainable product development. In our specially equipped ovens, climatic chambers and our temperature shocker, we cover a wide range of temperature and humidity ranges and enable rapid lifetime testing (Accelerated Lifetime Testing)

Temperature Shock Test Cabinet

To investigate the effect of rapid temperature change on materials and products, we use the Weiss ShockEvent T/60/V2 temperature shock test chamber. The dual-chamber design of this device allows for very fast and extreme temperature changes. This makes it possible to detect damage processes in materials and products that would not be apparent through a slow temperature change, or only after a very long period of stress.

Climate test chambers

To investigate the effects of environmental conditions on materials and products, the ATT Discovery DM340 C ES and DY110 C climatic chambers are available at our research department. These devices can be used to realize test conditions in a wide variety of temperature and humidity ranges in order to be able to make statements about damage mechanisms or durability. External measurements can also be carried out on the exposed materials and products via special inlets in the climatic chambers.
