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.

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. --------------------------------------------------------------------------------------------------------------------------------------------------------------------- Pr?face? Ce document constitue la troisi?me ?dition de la CAN/CSA-Z431, Principes fondamentaux et de s?curit? pour l'interface homme-machine, le marquage et l'identification - Principes de codage pour les indicateurs et les organes de commande. Il s'agit de l'adoption, avec exigences propres au Canada, de la norme CEI (Commission ?lectrotechnique Internationale) 60073 (sixi?me ?dition, 2002-05). Ce document remplace l'?dition ant?rieure publi?e en 2002 sous la d?signation CAN/CSA-Z431, Principes fondamentaux et de s?curit? pour les interfaces homme-machines, le marquage et l'identification - Principes de codage pour les dispositifs indicateurs et les organes de commande (norme CEI/IEC 73:1996 adopt?e). Domaine d'application La pr?sente Norme internationale ?tablit des r?gles g?n?rales en vue d'attribuer une signification particuli?re ? certaines indications visuelles, acoustiques et tactiles de fa?on ? ?accro?tre la s?curit? des personnes, des biens et/ou de l'environnement en r?alisant de fa?on s?re la surveillance et la commande des ?quipements ou des proc?d?s; ?faciliter la surveillance, la commande et la maintenance ad?quates des ?quipements ou des proc?d?s; ?faciliter la reconnaissance rapide des conditions de commande et de la position des organes de commande. La pr?sente norme est d'application g?n?rale: ?allant de cas simples tels que les voyants de signalisation, boutons-poussoirs, indicateurs m?caniques, diodes ?lectroluminescentes (DEL) ou consoles de visualisation jusqu'aux salles de commande ?tendues pouvant comprendre une grande vari?t? d'appareils et destin?s ? la conduite d'une machine ou d'un proc?d?; NOTE Il convient que les principes de codage soient appliqu?s sans modification aux consoles de visualisation. ?quand la s?curit? des personnes, des biens et/ou de l'environnement est en jeu, et aussi quand les codes mentionn?s plus haut sont utilis?s afin de faciliter la surveillance et la commande ad?quates d'un ?quipement; ?quand un codage particulier est sp?cifi? par un comit? d'?tudes pour une function particuli?re.
