Testing Institute for Rail Vehicles

Since 2008 we have been accredited according to DIN EN ISO / IEC 17025, confirming our competence in carrying out static and dynamic strength tests on rail vehicles or their components.

In addition to the accredited scope of testing, other testing services are carried out, e.g. tests to gain knowledge or for functional tests.
