Many sets of biodynamic experimental data of the hand-arm system have been reported. Some of them have also been used to synthesize the data used for constructing the models recommended in ISO 10068 (1998). However, a fairly large percentage of the reported data, including those recommended in the standard, are questionable. The objectives of this study are to evaluate the reported experimental data measured on the zh-axis (ISO 8727, 1997) and to identify those that are relatively reliable for further applications. The basic characteristics of the response expressed as the mechanical impedance of the system are clarified and used to conduct the evaluation and selection of the reported data. A model that provides a reasonable simulation of the hand-arm structures was also used to evaluate and filter the data. This study confirmed that some of the reported experimental data are unreliable. On the other hand, this study also identified three sets of data that can be used to represent the mechanical impedance of the hand-arm system coupled on a 40 mm cylindrical handle with a hand and arm posture similar to that specified in ISO 10819 (1996). The results of this study may be used to help build better biodynamic models and to improve ISO 10068.
