Time relays and coupling relays for industrial and residential use - Part 1: Requirements and tests

This part of the IEC 61812 series applies to time relays and coupling relays for industrial applications (e.g. 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 relays with specified time functions and coupling relays, other than measuring relays. This document defines type test and routine test to confirm the service condition.

Relais temporisés et relais de de couplage pour applications industrielles et résidentielles - Partie 1: Exigences et essais

IEC 61812-1:2023 est disponible sous forme de IEC 61812-1:2023 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 61812-1:2023 s'applique aux relais temporisés et aux relais de couplage pour applications industrielles (par exemple, systèmes industriels de commande, d'automatisation et de signalisation) ainsi qu'aux dispositifs de commande électrique automatiques destinés à être utilisés dans, sur ou avec des équipements pour applications résidentielles et analogues. Le terme "relais", utilisé dans le présent document, comprend tous les types de relais temporisés et de relais de couplage, hormis les relais de mesure. Le présent document définit l'essai de type et l'essai individuel de série qui visent à confirmer la condition de service. Les définitions des différents types de relais temporisés utilisés dans la série IEC 61812 sont données en 3.2. L'IEC 61812-1:2023 annule et remplace la deuxième édition parue en 2011. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) mise à jour des références; b) ajout d'exigences relatives à l'appréciation du risque; c) ajout d'exigences relatives à l'essai individuel de série; d) renumérotation des paragraphes selon un ordre plus logique; e) clarification de l'exigence relative aux chocs; f) ajout d'exigences de cybersécurité pour les systèmes d'automatisation et de commande industrielles; g) ajout d'une exigence d'écoconception; h) ajout d'une référence au dictionnaire de données commun; i) ajout de termes et définitions relatifs aux types de relais; j) ajout des relais de couplage dans le titre; k) ajout des relais de couplage dans le domaine d'application.
