This work was carried out to evaluate the magnetic field level on-board Bombardier rolling stock and comparing the measured values with the limits for human exposure. The used instrumentation and the developed procedures are presented. Attention is on the initial specifications as per applicable regulations and standards and the realization of the measurement setup. The reported results consist of sample time domain measurements, related spectra and comparison with normative limits. Besides the statement of Type B uncertainty for the measurement chain, the same results are also used to evaluate other metrological performances (sensitivity to sensor location due to spatial distribution, repeatability and reproducibility).

Abstract
This work was carried out to evaluate the magnetic field level on-board Bombardier rolling stock and comparing the measured values with the limits for human exposure. The used instrumentation and the developed procedures are presented. Attention is on the initial specifications as per applicable regulations and standards and the realization of the measurement setup. The reported results consist of sample time domain measurements, related spectra and comparison with normative limits. Besides the statement of Type B uncertainty for the measurement chain, the same results are also used to evaluate other metrological performances (sensitivity to sensor location due to spatial distribution, repeatability and reproducibility).
