Noise emissions in the environment measured as sound power (L
WA
) in conformity with EC directive
2000/14/EC.
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).
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
