Sources
The vibration information and the calculation
procedure is based on “ISO/TR 25398 Mechanical
Vibration - Guideline for the assessment of exposure
to whole body vibration of ride on operated
earthmoving machines”. Harmonized data is
measured by international institutes, organizations
and manufacturers.
This literature provides information about assessing
the whole body vibration exposure of operators of
earthmoving equipment. The method is based on
measured vibration emission under real working
conditions for all machines.
You should check the original directive. This
