Quality
Committed to the quality of our products and services, we undergo regular certification in accordance with DIN EN ISO 9001. TÜV first certified our quality management system in 1997.
In July 2025, the TÜV Rheinland inspectors visited us once again to thoroughly examine all our processes and workflows as part of the recertification process in accordance with DIN EN ISO 9001:2015. Once again, we were able to receive the TÜV Rheinland certificate without any objections.
This reaffirms the success of our customer-focused and quality-conscious approach, and means that our customers can continue to expect the highest levels of transparency, reliability, efficiency and service.
