IEC 60073 pdf download – Basic and safety principles for man-machine interface, marking and identification – Coding principles for indicators and actuators
1 scope
This International Standard establishes general rules for assigning particular meanings tocertain 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 whichmay 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 withoutmodification.’
– 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 ofequipment;
where a particular kind of coding is to be assigned by a technical committee to a specialfunction.

3Definitions
For the purposes of this standard, the following definitions apply.
3.1
coding
systematic representation of specific signals or values by another set of signals,which has toconform to a definite set of rules
[IEC61310-1:1995,definition 3.22]
3.2
indicator
mechanical, optical or electrical device or a part of device providing visual, acoustic or tactileinformation
3.2.1
acoustic signal
message conveyed by means of tone,frequency and intermittency,emanating from a soundsource
3.2.2
tactile signal
message conveyed by means of vibration, force,surface roughness, contour or position
3.2.3
visual signal
message conveyed by means of brightness,contrast, colour,shape, size or position
3.3
actuator
part of the actuating system which receives a human actuating action[IEC 60447: 1993, definition 3.1]
NOTEFor the purposes of this standard, the actuator in the case of an interactive screen display is considered tobe that part of the screen display which represents the actuator function.
3.4
mechanical indicator
indicator which forms an integral part of a mechanical or electromechanical switching device(e.g.circuit-breaker) and which indicates whether it is in the OPEN or CLOSED position or anintermediate position (e.g. star position of a star-delta starter) but which is not intended as amanual actuator
3.5
man-machine interface (MMI)
parts of the equipment intended to provide a direct means of communication betweenthe operator and the equipment, and which enable the operator to control and monitor theoperation of the equipment
NOTE Such parts may include manually operated actuators,indicators and screens.[IEC 60447:1993, definition 3.3]
3.6
signal light
object or apparatus designed to emit a light signal[IEV 845-11-05]
3.7
light emitting diode (LED)
solid-state device embodying a p-n junction，emitting optical radiation when excited by anelectric current
[IEV 845-04-40]
3.8
illuminated actuator
actuator with an integrated light source giving visual indication by illumination.The operationof the light source may be related to or independent of the actuator action
3.9
hue
attribute of a visual sensation according to which an area appears to be similar to one of theperceived colours, red,yellow,green, and blue, or to a combination of two of them
[IEV 845-02-35]
3.10
brightness
attribute of a visual sensation according to which an area appears to emit more or less light[lEV 845-02-28]
