Noise emission levels 1
One labels indicating the machine noise level is affixed on the machine.
q
Sound pressure level at the operator's station, measured
according to ISO6396 (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 2.5 dB, in accordance with
ISO 11201
Vibration levels 1
When used for its intended purpose, levels of vibration for the earth-moving machine transmitted from the opera-
tor’s seat are lower than or equal to the tested vibrations for the relative machinery class in compliance with ISO
7096.
The actual acceleration value for the hands and arms is less than or equal to 2.5 m/s², the uncertainty for this
value is 0.22 m/s² according to EN12096:1997.
The actual acceleration value for the body is less than or equal to 0.5 m/s², the uncertainty for this value is 0.17 m/
s² according to EN12096:1997.
These values were determined using a representative machine and measured during the typical operating condi-
tion indicated below according to the measurement procedures that are defined in the standards ISO 2631/1 and
ISO 5349.
