This Standard specifies safety-related requirements for actuators, operated by the hand or by other parts of the human body, at the man-machine interface.It gives general requirements for - the standard direction of movement for actuators;the arrangement of an actuator in relation to other actuators; andthe correlation between an action and its final effects.It is based on IEC 60447, but is also applicable to non-electrotechnical technologies, such as mechanical and fluid-powered systems.It covers single actuators as well as groups of actuators forming part of an assembly.
