Scope

This International Standard establishes general rules for assigning particular meanings to certain visual, acoustic and tactile indications in order to

  •  increase the safety of persons, property and/or the environment through the safe monitoring and control of the equipment or process;
  •  facilitate the proper monitoring, control and maintenance of the equipment or process;
  •  facilitate the rapid recognition of control conditions and actuator positions.


This Standard is for general application:

  •  from simple cases such as single indicator lights, push-buttons, mechanical indicators, light emitting diodes (LEDs) or video display screens to extensive control stations which may include a wide variety of devices for controlling an equipment or process;


NOTE Application of the general coding principles for displays on screens should be carried out without modification.

  •  where the safety of persons, property and/or the environment is involved, and also where the above-mentioned codes are used to facilitate the proper monitoring and controlling of equipment;
  •  where a particular kind of coding is to be assigned by a technical committee to a special function.
