Note 1: Equivalent noise level is, according to
ISO 22868, calculated as the time--weighted en-
ergy total for noise levels under various working
conditions with the following time distribution,
1/3 idle, 1/3 full load, 1/3 full speed.
Note 2: Equivalent vibration level is, according
to ISO 22867, calculated as the time--weighted
energy total for vibration levels under various
working conditions with the following time dis-
tribution: 1/3 idle, 1/3 full load, 1/3 full speed.
