This document describes the coupling parameters between the hands of a machine operator and a vibrating surface of the machine.
The coupling between the hand and the vibrating surface can be described using different parameters and component parts of these parameters:
— force parameters, such as push, pull and grip;
— parameters such as pressure exerted on skin.
In addition, Annexes A, B, C, D and E provide guidelines for measuring procedures, the measurement of the force and pressure parameters, and information on the requirements for measuring instrumentation, as well as a calibration method.
This document does not deal with forces which act tangentially to the hand.
