Note 1: Noise emissions in the environment measured as sound power (L
WA
) in conformity with EC directive
2000/14/EC.
Note 2: Equivalent sound pressure level, according to ISO 22868, is calculated as the time-weighted energy total
for different sound pressure levels under various working conditions. Typical statistical dispersion for equivalent
sound pressure level is a standard deviation of 1 dB (A).
Note 3: Equivalent vibration level, according to ISO 22867, is calculated as the time-weighted energy total for
vibration levels under various working conditions. Reported data for equivalent vibration level has a typical
statistical dispersion (standard deviation) of 1 m/s
