Noise emissions in the environment are measured as sound power (L
WA
) in conformity with directive
2000/14/EC. The difference between guaranteed and measured sound power is that the guaranteed sound
power includes dispersion in the measured result and variations between different units of the same product
according to directive 2000/14/EC.
2
Equivalent sound pressure level, according to EN ISO 19432-1, is calculated as the time-weighted energy to-
tal for different sound pressure levels in various working conditions. Reported data for equivalent sound pres-
sure level for the product has a typical statistical dispersion (standard deviation) of 1 dB (A).
3
Equivalent vibration level, according to EN ISO 19432-1, is calculated as the time-weighted energy total for
vibration levels in different work conditions. Reported data for equivalent vibration level has a typical statistical
dispersion (standard deviation) of 1m/s
