The purpose of this study is to determine the repeatability and the reproducibility between different laboratories for force measurement source in blocking condition. The measurement procedure is shared between the laboratories. The study shows a good reproducibility for RMS frequency band between 20Hz to 2 kHz and for all interfaces. Contrariwise, the peak harmonic levels generated by the source (harmonics 1 to 10) show a bad repeatability and reproducibility. This ascertainment is probably incriminated to cavitation problem who affect force measurement repeatability.
