Dynamic characterisation of the electronic instrumentation used in the calibration of fatigue testing machines

Fatigue testing machines dynamically apply forces to the device under test. Standards for the characterisation of fatigue testing machines exist but their instrumentation is not traceable to national electrical standards. Thus, the dynamic characterisation of the electronic instrumentation used in the calibration of fatigue testing machines is considered. In particular, the principles of operation and the evaluation of the National Physical Laboratory´s dynamic force standard for the characterisation of the electronic instrumentation used in the calibration of fatigue testing machines under static and dynamic conditions are given
