Note 1: Equivalent noise level is, according to ISO 7182 and ISO 9207, calculated as the time--weighted energy total for noise levels un- der various working conditions with the follow- ing time distribution, 1/2 idle, 1/3 full load, 1/3 full speed.

Note 2: Equivalent vibration level is, according to ISO 7505, 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.
