Temperature change / climate

Temperature change tests make it possible to deliberately let products and components age. This test is used to examine the effects of frequent temperature changes on the specimen, for example the behavior of the specimen in the case of rapid changes to the ambient temperature and humidity. It is furthermore possible to control and evaluate specimens with our large portfolio of measuring technology and analysis technology.

Condensation test

The condensation test simulates the condensation at electronic components. It is realized with a specially regulated water bath. During the condensation phase the climate control is switched off and the temperature is only controlled with the water bath. In the process the specimens are located in the climate chamber under a plastic hood in order to eliminate differing air speeds during the test.

This test simulates the free fall of a component to the ground, similar to the way it can occur during the complete process chain up to the correct installation of the component. The purpose of the test is to ensure that a component installed in the vehicle that is outwardly undamaged, really is free of hidden damage or preliminary damage.
