TESTS IN THE ACCREDITED ENVIRONMENTAL SIMULATION LABORATORY
No matter what the environmental conditions are under which one of our developed products must perform properly, we have the means to simulate them in our own laboratory. We can create extreme temperatures, generate constant temperature changes, or induce thermal shocks. We expose the product to strong vibrations or heavy accumulations of dirt or check the proper functioning under the potential effect of high humidity. Our environmental tests are performed according to the current environmental simulation standards, as well as in compliance with specified customer standards, such as those of VW, BMW, MAN, Liebherr or John Deere. Our employees not only rely on their many years of experience or the most modern technology, but above all on their motivation to provide our customers with the best possible advice. They are ready to enter new areas and of course, it is always our goal to act promptly, transparently and reliably.
The »Deutsche Akkreditierungsstelle GmbH« (DAkkS) confirms that our laboratory has the competence to carry out examinations in the field of environmental simulations for electronic and electronic components for road vehicles according to DIN EN ISO / IEC 17025: 2005.
We will gladly support you with the following queries:
- statistical test arrangement
- project specification
- implementation
- statistical evaluation
- cause analysis (e.g. using a 8D report)
- definition and implementation of corrections
- sustainability assessment
- overall fault management
We look forward to your call or e-mail!

Electro-Pneumatic Test Bench
The electro-pneumatic test bench was developed in-house by the brehmergroup lab. Brian Schmidt designed and completed the test bench in coordination with our laboratory manager Sebastian Sohn. The test bench allows endurance tests to be conducted on buttons and / or switches exposed to the environment. The actuating force and angle are adjustable. Due to the ability to control the individual cylinders separately, it is possible to program custom test procedures. The controllers are cascadable, which allowed up to 120 test specimens to be controlled in any order by a single test program.
Temperature
The test bench described here can be used in a temperature range of -20°C to +80°C.
Actuating force
The force transferred by each of the pneumatic cylinders can be set to any value within a wide range by applying air pressure. Contact between the cylinder head and the test specimen is made using a screw-mounted attachment that can be adjusted according to the particular test requirements.
