Control systems in the process industry - Electrical and instrumentation loop check (IEC 62382:2024)
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:

Systèmes de commande pour les procédés industriels - Contrôle de boucle des circuits électriques et des appareillages (IEC 62382:2024)
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.
Krmilni sistemi v procesni industriji - Preverjanje električnih in merilnih zank (IEC 62382:2024)
Standard IEC 62382:2024 določa postopke in specifikacije za preverjanje zank, kar vključuje dejavnosti med dokončanjem izdelave zanke (vključno z namestitvijo in preverjanjem od točke do točke) in začetkom hladnega zagona. Ta dokument se uporablja za gradnjo novih obratov in za razširitev ali rekonstrukcijo (npr. preoblikovanje) električnih in merilnih (E&I) naprav v obstoječih obratih (vključno s sistemi PLC, DCS, na ploščo pritrjenimi merilnimi instrumenti in terenskim merjenjem). Ne vključuje podrobnega preverjanja napajalnih sistemov, razen v primerih, ko se navezujejo na preverjane zanke (npr. zaganjalnik motorja ali napajanje štirižičnega oddajnika). Preverjanje zanke je mogoče izvajati skozi celoten življenjski cikel obrata. Ta dokument se uporablja tudi, kadar se preverjanje zanke izvaja po zagonu. V tem dokumentu je opisano, kaj naj bi se preskušalo, ne pa tudi način izvajanja preskusa (zaradi širokega nabora razpoložljivih tehnologij in opreme).
Namen tega dokumenta je omogočiti vsem strankam, vključno z lastnikom, namestiteljem in prodajalcem, da jasno določijo in se dogovorijo o obsegu dejavnosti in odgovornosti, vključenih v izvajanje teh preskusov, s čimer se dosežeta pravočasna dobava in prevzem avtomatizacijskega sistema. Dejavnosti iz tega dokumenta je mogoče uporabiti kot smernico in prilagoditi posebnim zahtevam procesa, obrata ali opreme.
Ta izdaja v primerjavi s prejšnjo vključuje naslednje pomembne tehnične spremembe:
a) vsebina prejšnje izdaje je bila v splošnem preurejena (informativna vsebina je bila premaknjena v dodatke);
b) namesto obrazcev na podlagi vrste I/O v dodatkih A do E standarda IEC 62382:2012 je podan primer splošnega obrazca za preverjanje zanke;
c) navedeni so dodatni sklici na druge veljavne standarde.

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which

INTRODUCTION
The inspection and verification of the individual measurements and controls in conjunction with
the control systems used to monitor these devices is referred to as loop check. In industry,
numerous methods and philosophies are used to check the instrumentation and controls after
mechanical installation within projects for modified or new facilities.
This document was created to provide a better understanding of what loop check consists of
and also to provide a standard methodology for executing a loop check.
Annex A provides examples of checks for various loop components to aid the user in
establishing the desired loop check plans for a specific project. Annex B provides an example
of a loop check form.
