The task requirements do not need to be evaluated precisely, therefore the detailed evaluation procedure given in 5.2 and 5.3, show classification systems that have been found to be sufficiently accurate. The characteristics of the various types of control actuator need to be considered to determine the available selection options. This standard gives information on both movement characteristics and grip characteristics. In many cases some of the characteristics will have been predetermined by the task requirements. Movement characteristics: j) Type of movement; k) Axis of movement; l) Direction of movement; m) Continuity of movement; n) Angle of rotation for continuous rotary movements > 180° Grip characteristics: o) Type of grip; p) Part of hand applying force; q) Method of applying force. The above categories a - q are used throughout this standard. The shorter descriptions given in brackets after the full descriptions are used in table headings where space is limited.
