TÜV AUSTRIA TVFA Prüf- und Forschungs GmbH

http://www.tvfa.at/

As an independent testing laboratory accredited according to EN ISO/IEC, we carry out a wide range of tests in the field of railway technology. In our laboratories, infrastructure components from sub-ballast mats over sleepers, fastening systems, rails to the overhead conductors and catenary components are subjected to in-depth testing.
On rolling stock components, we carry out strength and fatigue tests on bogie frames, engine mounts, axle box bearings, wheelsets and rubber composite components (bearings, springs, etc.).
