Basic and Safety Principles for Man-Machine Interface, Marking and Identification - Coding Principles for Indication Devices and Actuators
|Publication Date:||1 January 2002|
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;
- 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.
