Note 2: Equivalent sound pressure level, according to ISO 22868, is calculated as the time-weighted energy total for noise pressure levels under various working conditions with the following time distribution: 1/3 idling, 1/3 max. load, 1/3 max. speed. Note 3: Equivalent vibration level, according to ISO 22867, is calculated as the time-weighted energy total for vibration levels under various working conditions with the following time distribution: 1/3 idling, 1/3 max. load, 1/3 max. speed. 115 13 81-26 Rev.3 2009-01-14 English - 39
