Evaluation of human exposure to whole-body vibration, Part 1: General requirements

Defines methods for the measurement of periodic, random and transient whole-body vibration and indicates the principal factors that combine to determine the degree to which vibration exposure will be acceptable. Informative annexes provide guidance based on current opinion on the possible effects of vibration on health, comfort and perception and motion sickness. This Standard is identical with and has been reproduced from ISO 2631-1:1997.
