This is the task for the calibration and testing center (KPS). Here it is ensured that the requirements of DIN EN ISO 9001 (quality management) and DIN ISO 10012 (measurement management systems) are met.
Our aim is to provide customers with a complete range of solutions for measuring and testing tasks. We have specialized in railway-typical test and measurement methods.
Accreditation is a prerequisite for recognition as an approved test center for test equipment monitoring within the area of responsibility of the Federal Railway Authority. For most calibrations and tests, the test location is specified with the test procedure. Measuring machines and equipment such as wheelset processing machines, wheelset diagnostic systems, measuring tracks and mechanical and electrical test equipment are calibrated by our test teams on site at the customer.
In the case of transportable measuring equipment, the location of the test depends on the requirements placed on their accuracy. In order to realize the smallest measurement uncertainties, efficient measurement methods are available in our precision laboratories.

Calibration and testing services
1) Accredited Calibrations: Competent - Neutral - Independent
Accredited calibrations ensure international comparability and recognition of the certificates issued. They are recommended, among other things, because of the traceability to national standards with low measurement uncertainty, for example for reference measuring devices and when confirmation by official bodies is required.
Calibration of measuring and test equipment with competence:
- The basis is the calibration laboratory accredited by DAkkS (German Accreditation Body) for the specialist areas of length, pressure, force, torque and temperature, electrical parameters, frequency and time interval in accordance with DIN EN ISO/IEC 17025.
