National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Experimental Evaluation of International Standard (ISO (International Organization for Standardization) 2631-1974) for Whole-Body Vibration Exposures.

PB89230049

Publication Date	1976
Personal Author	Guignard, J. C.; Landrum, G. J.; Reardon, E.
Page Count	252
Abstract	A study was conducted to evaluate 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 used the Western Gear mechanical vibration machine. The primary performance measure used in the 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. 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 than is typical of the working day.
