Two labels indicating the machine noise level are affixed on the machine.
• Sound pressure level at the operator's station, measured
according to ISO 6396 (Dynamic test method, simulated
working cycle).
The maximum value of the standard deviation of the meas-
ured time-averaged A-weighted emission sound pressure
level at the operator's position is 2.5dB, in accordance with
ISO 11201
• Sound power level emitted by the machine, measured ac-
cording to ISO 6395 (Dynamic test method, simulated
working cycle). This is the guaranteed value as specified in
European directive 2000/14/EC.
This value includes an uncertainty of 0.7 dB.
