The maximum forces measured by the machines in this round robin are in good agreement. This general result shows that the static force calibration of instrumented strikers is quite robust, and that the various striker designs evaluated here performed in a predictable manner. One machine in the round robin was identified as an outlier by the dynamic force measurement results, indicating that dynamic testing may be a useful approach to check the performance of the instrumented machine and measurement system.
