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

IEC 62382:2012 describes the steps recommended to complete a loop check, which comprises the activities between the completion of the loop construction (including installation and point-to-point checks) and the start-up of cold commissioning. This standard is applicable for the construction of new plants and for expansion/retrofits (i.e. revamping) of E&I installations in existing plants (including PLC, BAS, DCS, panel-mounted and field instrumentation). This second edition cancels and replaces the first edition published in 2006 and constitutes a technical revision. The main changes with respect to the previous edition are: The definition of the documents mentioned in the standards is in accordance with IEC 62708: Documents for Electrical and Instrumentation Projects in the Process Industry. Subclause 6.3 has been revised.

Systèmes de commande pour les procédés industriels - Contrôle de boucle des circuits électriques et des appareillages

La CEI 62382:2012 décrit la marche à suivre recommandée pour réaliser 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. La présente norme s'applique à la construction de nouvelles usines, ainsi qu'à l'extension ou à la modernisation des installations de systèmes électriques, d'appareillage et de commande (Electrical and Instrumentation and control systems, E&I) dans les usines existantes (automates programmables, systèmes d'automatisation de bâtiment [Building Automation Systems, BAS], systèmes à commande distribuée, appareils montés sur panneau et appareils de terrain compris). Cette deuxième édition annule et remplace la première édition parue en 2006 et constitue une révision technique. Les principales modifications par rapport à l'édition précédente sont: La définition des documents mentionnés dans les normes est conforme à la CEI 62708: Documents for Electrical and Instrumentation Projects in the Process Industry. Le paragraphe 6.3 a été révisé.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62382 has been prepared by subcommittee 65E: Devices and
integration in enterprise systems, of IEC technical committee 65: Industrial-process
measurement, control and automation.
This second edition cancels and replaces the first edition published in 2006. This edition
constitutes a technical revision.
The main changes with respect to the previous edition are listed below:
– The definition of the documents mentioned in the standards is in accordance with
IEC 62708: Documents for Electrical and Instrumentation Projects in the Process Industry.
– Subclause 6.3 has been revised.
