The TÜV auditors visited us in Mainhausen with a precise eye and detailed checks of processes and documents. Their annually recurring audits for ISO 9001 and ISO 14001 are standard, but we are nevertheless pleased that they went through without any problems and that the TÜV auditors were able to confirm our ISO certificates. There were no deviations or complaints. And so we can once again use these important certificates to meet the requirements of our customers, the authorities and our own quality and environmental management.
