PJM has been accredited for pantographs

PJM has expanded its scope as an accredited test center in accordance with ISO/IEC 17025 and now also tests the dynamic interaction between pantograph and overhead contact line. In addition to measurements in accordance with EN 50317, the accreditation also includes simulations in accordance with EN 50318, making PJM the only company in Austria with accreditation for the specialist area of pantographs.

Over the past two years, the Austrian system specialist has invested in the infrastructure of the new department. The pantograph test rig for calibrating the measuring system - as well as the technical equipment for other areas - has been set up at the company‘s site in Graz. Extensive tests in the wind tunnel have proven that the measuring system is non-reactive. With the existing measuring equipment, tests can be carried out with up to two measuring pantographs, which means that multiple-unit operations can also be done.

The requirements for the interaction between pantographs and the overhead contact line system of the new servicejet for ÖBB had been tested in summer. In the coming weeks, the measurement technology team will be testing another rail vehicle in single and multiple-unit operations.

A total of six specialist areas are accredited: running characteristics, strength, brake, acoustics, aerodynamics and pantograph. In combination with comprehensive expertise in engineering and in the development and production of instrumented wheelsets, PJM has established itself as a reliable partner in the testing of rail vehicles all over the world and in the handling of overall rail vehicle testing.
