Scope: This part of GB/T 22655 specifies the general method for measuring hand-transmitted vibrations on three orthogonal axes for hand-held screwdrivers and impact wrenches, measured in an octave band with a center frequency of 8 Hz to 1000 Hz. This part applies to the method of evaluating hand-transmitted vibration by frequency-weighted vibration acceleration, and does not specify the vibration limit. The assessment of human exposure to hand-transmitted vibrations under workplace conditions can be carried out in accordance with ISO 5349-1 and ISO 5349-2.
