Certificates and standards

Outstanding quality. Backed up by recognised certificates from independent testing organisations.


Certified quality

Our longstanding customers are already familiar with our high standards, while everyone else receives a copy in black and white.

To ensure that our quality standards remain at a consistently high level, we operate stringent internal controls. We also undergo regular audits by customers and by accredited certification bodies.

Quality and environmental objectives – DIN EN ISO 9001, 14001, ISO/TS 169649, EN 9100 and IRIS
