Preface

This is the third edition of CAN/CSA-Z431, Basic and safety principles for man-machine interface, marking and identification – Coding principles for indicators and actuators, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 60073 (sixth edition, 2002-05). It supersedes the previous edition, published in 2002 as CAN/CSA-Z431, Basic and safety principles for man-machine interface, marking and identification – Coding principles for indication devices and actuators (adopted CEI/IEC 73:1996).

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.
