scope:

This part of IEC 61310 specifies requirements for visual, acoustic and tactile methods of
indicating safety-related information, at the human-machine interface and to exposed persons.
It specifies a system of colours, safety signs, markings and other warnings, intended for use
in the indication of hazardous situations and health hazards and for meeting certain
emergencies. It also specifies ways of coding visual, acoustic and tactile signals for indicators
and actuators to facilitate the safe use and monitoring of the machinery.
This standard is based on IEC 60073 with regard to coding by colour and alternative means,
but is not limited to electrotechnical aspects.
