For making estimates of daily vibration exposures, useful
information may be found in CEN/TR 15350: 2006,
"Mechanical vibration - Guideline for the assessment of
exposure to hand-transmitted vibration using available
information including that provided by manufacturers of
machinery"
*These declared values were obtained by laboratory type
testing in compliance with the stated standards and are not
adequate for use in risk assessments. Values measured
in individual work places may be higher than the declared
values. The actual exposure values and risk of harm
experienced by an individual user are unique and depend
upon the way the user works, the workpiece and the
workstation design, as well as upon the exposure time and
the physical condition of the user. We, Chicago Pneumatic,
cannot be held liable for the consequences of using the
declared values, instead of values reflecting the actual
exposure, in an individual risk assessment in a work place
situation over which we have no control.
