PJ Messtechnik
PJ Messtechnik is an accredited testing laboratory in accordance with ISO/IEC 17065 and a specialist in engineering for rail vehicles - two complementary areas of expertise that together ensure reliable and well thought-out solutions.
Your reliable partner for measurement technology in rail transportation
For two decades, we have stood for precise and reliable measurement technology in rail transportation. Our many years of specialization have enabled us to build up and continuously develop in-depth expertise. PJ Messtechnik was the first privately accredited testing laboratory in Austria to be recognized by the Federal Ministry just two years after it was founded - proof of the high quality standards we have pursued from the very beginning.
Our testing laboratory expertise
- Vehicle dynamics
- Fatique strength
- Brake tests
- Acoustics
- Aerodynamics
- Pantograph (only test center in Austria)
- EMC (via our subsidiary EMC Services)
In the focus of engineering: Lowest possible weight with maximum structural safety
This expertise is complemented by our second major competence: engineering, in which PJ Messtechnik has done truly pioneering work: For the first time, we have successfully transferred topology optimization, which originally came from the aerospace industry, to freight wagons. The aim here is to develop components with the lowest possible weight and at the same time maximum structural safety - a combination that is particularly in demand in rail transport.
PJM is also one of the internationally recognized specialists in the field of multi-body simulation and finite element calculation. With sound methodological expertise and modern simulation technology, we support the development of safe, efficient and sustainable vehicles.
