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).
19
Vibration level, according to EN 60745-2-13. Reported data for vibration level has a typical statistical disper-
sion (standard deviation) of 1 m/s
with a bar length and recommended chain type. If the machine is fitted with a different bar length, the vibration
level may vary by max ± 1.5 m/s
20
Equivalent vibration level is measured and calculated as for combustion engine powered chainsaws. These
figures are quoted to be able to compare vibration data regardless of type of engine according to ISO
22867:2011.
