PERFECTION IS OUR PASSION – TESTS IN THE ACCREDITED ENVIRONMENTAL SIMULATION LABORATORY
Regardless of the environmental conditions under which a product you have developed must function perfectly, you can have it tested safely in our accredited environmental simulation laboratory. We create extreme temperatures, generate constant temperature changes or thermal shocks. We expose the product to strong vibrations or a high level of dirt or test its proper function under the latent influence of high humidity. As part of this process, our environmental tests are carried out in
accordance with all current environmental simulation standards and at the same time in accordance with the specified customer standards, such as those of VW, BMW or MAN, Liebherr and 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.
DAkkS Deutsche Akkreditierungsstelle GmbH confirms that our testing laboratory has the competence according to DIN EN ISO/IEC 17025:2018 to perform tests in the field of ‘Environmental simulations on electronic and electronic components for road vehicles’. The accreditation is valid for the scope specified in the certificate annex D-PL-20176-01-00.
We will be happy to assist you with the following questions:
- Statistical test design
- Project specification
- Realisation
- Statistical evaluation
- Root cause analysis (e.g. using an 8D report)
- Definition and implementation of corrections
- Sustainability check
- Overall fault management
We look forward to receiving your call or e-mail!
If you have any questions or would like to share an idea with us, if you are interested in further information or would simply like to find out more about us and our work - in short: if we have piqued your interest, then please do not hesitate to get in touch with us.
