Noise emissions in the environment are measured as sound power (L
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.

Equivalent sound pressure level, according to EN ISO 19432-1, is calculated as the time-weighted energy
total for different sound pressure levels in different work conditions. Recorded data for equivalent sound
pressure level of the product has a standard deviation of 1 dB (A).
7
Equivalent vibration level, according to EN ISO 19432-1, is calculated as the time-weighted energy total
for vibration levels in different work conditions. Recorded data for equivalent vibration level has a standard
deviation of 1m/s
