Railway

TÜV AUSTRIA and TVFA offer independent testing, inspection and certification services as an accredited body to the rail industry (EN ISO/IEC 17020, 17025, 17065).

We test infrastructure components, rolling stock components and overhead lines. Our services include bogie testing, damping systems, ties, rail fastening systems, wheel and machine components, overhead lines and the connections and guy wires they require, as well as rails and rail joints.

TVFA also performs mechanical testing and characterisation of components and materials. We test under realistic conditions and have appropriate facilities, even for complex structures and large components. Our range of state-of-the-art metallographic methods completes our mechanical testing services.

We perform EMC and EMI measurements in the lab and on-site.

Railway fixed equipment testing and approval services

TVFA performs full approval testing for flash-butt or aluminothermic welding processes (EN 14587, EN 14730), rail fastening systems (EN 13481, EN 13146), sleepers (EN 13230, EN 16431). We perform fatigue and strength testing of wheelsets, bogies, frames according to EN 13749, UIC 515-4, UIC 615-4.

We also test any component or system, including insulated rail joints and clamping elements in accordance with technical delivery conditions.

Many customers ask for special tests during their R&D process, such as testing under special environmental conditions (from -70°C to high temperatures), unusual loads or measurement conditions and fatigue testing over long durations and corrosion tests in our salt spray chamber.

Advanced metallographic laboratory

TVFA operates a state-of-the-art metallographic laboratory. In collaboration with the Vienna University of Technology, it offers light microscopy and scanning electron microscopy (SEM/EDX) capabilities, as well as microhardness testing and full chemical analysis.

Inspection services, damage analysis and non-destructive testing

TVFA experts perform inspections on railway components, including welding joints for QA/QC, factory acceptance test or in case of damage assessments for all kinds of railway infrastructure components and systems. As part of the TÜV AUSTRIA Group, we offer access to the whole service range, offering standard and advanced non-destructive testing (NDT) methods.

Contact wire testing capabilities

TVFA performs approval tests and product certifications according to customer specifications. This includes clamping lengths up to 50m, heating up to 220°C, measuring of thermal expansion coefficients and transition points, vibration tests and damage analyses of cables and wires in accordance with German standard VDI 3822.
