Values determined according to procedure described in annex F of
EN 13862
Measurements are made with new machines. Real values in the field could vary the simple
one with the double according to operating conditions, depending on:
o
Material
o
Cutting depth
o
Machine wear
o
Lack of maintenance
o
Tool not adapted to application
o
Tool in bad shape
o
Non-specialised operator
Vibrations exposure time depends on cutting performance too
(adaptation machine / tool / material / operator)
When evaluating risks due to hand-arm vibration, you need to take into account effective
usage at rated power of machine during a full day of work; quite often you will realise that
effective utilisation time represents around 50% of overall duration of work. You have to
consider, of course, breaks, water feeding, preparation of work, time to move the machine,
disk mounting…
