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 safemonitoring 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 wherethe 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.

3 Definitions
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 to conform to a definite set of rules
[IEC 61 31 0-1 : 1 995, definition 3.22]
3.2
indicator
mechanical, optical or electrical device or a part of device providing visual, acoustic or tactile information
3.2.1
acoustic signal
message conveyed by means of tone, frequency and intermittency, emanating from a sound
source
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
