A study was conducted to evaluate systematically the current International Organization for Standardization (ISO) international standard (ISO-2631-1974) for human body exposure to whole body vibration with particular reference to the range 2 to 16 hertz (Hz) and exposure durations from 16 minutes to 8 hours. Eight male university students participated in the study which employed the Western Gear mechanical vibration machine. The primary performance measure used in this study was a one dimensional, horizontal, visual compensatory tracking task. Additional performance tests measured not only tracking but also attentional selectivity, auditory vigilance and visual acuity. Attentional selectivity was measured using a modified version of the Hockey visual detection task. Also measured were kinesthetic sensitivity, manual dexterity, flicker fusion apparatus, dynamometer, and the Landolt broken ring test. Overall, a total of 14 tests of central or peripheral performance and physiological state were performed. The authors conclude that the ISO standards are overly protective and may unnecessarily restrict human work function if applied in industry, particularly for longer durations of exposure typical of the working day.
