Patents and certificates

The TÜV certification inspection procedure is a 3-months process, which gets accomplished by satisfying a strict list criteria. Completion of the technical inspection gives accreditation to the suppliers of the resources and raw materials prior to shipping, verifying the overall quality and added value of products. The effort was worth it. The certificate was presented, allowing the use of proof of origin “Made in Germany”.

Product development requires both proven effectiveness and optimized compatibility in the area of application. As one of the first companies in Germany to do so, our products have been tested and are certified by accredited testing facilities. Since 1998 our products are tested for effectiveness under testing procedures that have been especially developed for our products. Since 2011 our products are tested according to DIN regulations to fulfill the strict requirements of the automobile industry.
But our quality requirement claims more. In addition to the evidence of effectiveness provided by TÜV, we own approved compatibility tests for a big range of our products.
