Abstract
Whole body vibration is any oscillating mechanical
disturbance that vibrates within a frequency range of 0.5 to
80 hertz. There exist two vibration standards, International
standard, ISO 2631 and British Standard, BS 6841, that attempt
in different ways to evaluate human exposure to whole body
vibration. It was found that the ISO standard, which uesd an
equal sensation subjective method, has become outdated and
that the newer British standard, which evaluates vibration
levels using a more flexible vibration dose method is the
preferred guide to use. Although both standards are only
vibration evaluation guides, the continuing evolution of
standards like ISO 2631 and BS 6841 will provide for better
evaluation in the future.
