Annotation of standard text IEC 61812-1-ed.3.0 :
IEC 61812-1:2023 applies to time relays and coupling relays for industrial applications (for example control, automation, signal and industrial equipment) and for automatic electrical controls for use in, on, or in association with equipment for residential and similar use. The term “relay” as used in this document comprises all types of time relays and coupling relays, other than measuring relays. This document defines type test and routine test to confirm the service condition. Subclause 3.2 provides definitions for different types of time relays in use in the IEC 61812 series. IEC 61812-1:2023 cancels and replaces the second edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) update of references; b) addition of requirements for risk assessment; c) addition of requirements for routine test; d) renumbering of clauses to bring them into a more logical order; e) clarification of the requirement for shock; f) addition of cybersecurity requirements for industrial automation and control systems; g) addition of environmentally conscious design requirement; h) addition of common data dictionary reference; i) addition of terms and definitions of relay types; j) addition of coupling relays in title; k) addition of coupling relays in scope. LIEC 61812-1:2023 sapplique aux relais temporises et aux relais de couplage pour applications industrielles (par exemple, systemes industriels de commande, dautomatisation et de signalisation) ainsi quaux dispositifs de commande electrique automatiques destines a etre utilises dans, sur ou avec des equipements pour applications residentielles et analogues. Le terme "relais", utilise dans le present document, comprend tous les types de relais temporises et de relais de couplage, hormis les relais de mesure. Le present document definit lessai de type et lessai individuel de serie qui visent a confirmer la condition de service. Les definitions des differents types de relais temporises utilises dans la serie IEC 61812 sont donnees en 3.2. LIEC 61812-1:2023 annule et remplace la deuxieme edition parue en 2011. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) mise a jour des references; b) ajout dexigences relatives a lappreciation du risque; c) ajout dexigences relatives a lessai individuel de serie; d) renumerotation des paragraphes selon un ordre plus logique; e) clarification de lexigence relative aux chocs; f) ajout dexigences de cybersecurite pour les systemes dautomatisation et de commande industrielles; g) ajout dune exigence decoconception; h) ajout dune reference au dictionnaire de donnees commun; i) ajout de termes et definitions relatifs aux types de relais; j) ajout des relais de couplage dans le titre; k) ajout des relais de couplage dans le domaine dapplication.
