EN IEC 62382:2024

Control systems in the process industry - Electrical and instrumentation loop check

IEC 62382:2024 defines procedures and specifications for loop check, which comprises the activities between the completion of the loop construction (including installation and point-to-point checks) and the beginning of cold commissioning. This document is applicable for the construction of new plants and for expansion or retrofits (i.e. revamping) of electrical and instrument (E&I) installations in existing plants (including PLC, DCS, panel-mounted and field instrumentation). It does not include a detailed checkout of power distribution systems, except as they relate to the loops being checked (i.e. a motor starter or a power supply to a four-wire transmitter). Loop checks can be performed throughout the lifecycle of the plant. This document is also applicable when loop checks are performed after commissioning. This document describes what is intended to be tested but not how the test is performed, due to the wide range of technologies and equipment available. The intent of this document is to provide a means for all parties, including the owner, the installer and the vendor, to clearly establish and agree on the scope of activities and responsibilities involved in performing these tests in order to achieve a timely delivery and acceptance of the automation system. The activities described in this document can be taken as a guideline and adapted to the specific requirements of the process, plant or equipment. This edition includes the following significant technical changes with respect to the previous edition: a) general re-organization of the content of the previous edition, moving informative content to the annexes; b) replacing the forms based on I/O type in IEC 62382:2012, Annex A to Annex E with an example of a generic loop check form; c) providing additional references to other applicable standards.

Leittechnische Systeme in der verfahrenstechnischen Industrie - PLT-Stellenprüfung

Systèmes de commande dans l’industrie de transformation - Contrôle de boucle des circuits électriques et des appareillages

IEC 62382:2024 définit les procédures et les spécifications relatives à un contrôle de boucle, qui se compose des activités comprises entre l’achèvement de la construction de la boucle (installation et contrôles de point à point) et le début de la mise en service à froid. Il s'applique à la construction de nouvelles usines, ainsi qu'à l'extension ou à la modernisation des installations de systèmes électriques et instruments de fonctionnement (E&I - electrical & instrument) dans les usines existantes (PLC - programmable logic controller, DCS - distributed control system, appareils montés sur panneau et appareils de terrain compris). Elle ne comprend pas de vérification détaillée des réseaux de distribution d'électricité, hormis dans la mesure où ils sont rattachés aux boucles faisant l'objet du contrôle (c'est-à-dire dans le cas d'un démarreur de moteur ou d'une alimentation électrique pour un transmetteur à quatre fils). Les contrôles de boucle peuvent être effectués tout au long du cycle de vie de l’usine. Le présent document s'applique également aux contrôles de boucle effectués après la mise en service. Le présent document décrit ce qui est destiné à être soumis à l’essai et non la méthode d’essai en raison de la large plage de technologies et d’équipements disponibles. Le présent document a pour objet de permettre à toutes les parties, y compris le maître d’ouvrage, l’acheteur et l’installateur, de définir clairement et de convenir de l’étendue des activités et des responsabilités liées à l'exécution de ces essais, afin de finaliser la livraison et l'acceptation des systèmes d’automatisation dans les délais prévus. Les activités décrites dans le présent document peuvent être considérées comme des lignes directrices et être adaptées aux exigences spécifiques du processus, de l'usine ou de l'équipement. Cette troisième édition annule et remplace la deuxième édition parue en 2012. Cette édition constitue une révision technique. Les principales modifications par rapport à l'édition précédente sont les suivantes: a) réorganisation générale du contenu de l’édition précédente, en déplaçant le contenu informatif vers les annexes; b) remplacement, dans les Annexes A à E de l’IEC 62382, des formulaires fondés sur le type d’E/S par un exemple de formulaire générique de contrôle de boucle; c) ajout de références supplémentaires à d’autres normes applicables.
