Note 1: Noise emissions in the environment measured as sound power (L
EC. The difference between guaranteed and measured sound power is that the guaranteed sound power also includes
dispersion in the measurement result and the variations between different machines of the same model according to
Directive 2000/14/EC.
Note 2: Equivalent sound pressure level, according to EN ISO 19432, is calculated as the time-weighted energy total for
different sound pressure levels under various working conditions. Reported data for equivalent sound pressure level for
the machine has a typical statistical dispersion (standard deviation) of 1 dB(A).
Note 3: Equivalent vibration level, according to EN ISO 19432, 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
