(Main)Industrial systems, installations and equipment and industrial products - Identification of terminals within a system
Industrial systems, installations and equipment and industrial products - Identification of terminals within a system
IEC 61666:2010 establishes general principles for the identification of terminals of objects within a system, applicable to all technical areas (for example mechanical engineering, electrical engineering, construction engineering, process engineering). They can be used for systems based on different technologies or for systems combining several technologies. This second edition cancels and replaces the first edition of IEC 61666 published in 1997 and edition constitutes a technical revision. It includes the following substantial changes with respect to the previous edition: - the terminology used in the publication has been adapted to the one used in IEC 81346-1 Ed. 2; - a more comprehensive description of the designation principles is provided; - additional examples illustrating terminal designations related to the function aspect and location aspect are provided; - an additional example illustrating the use of terminal designation sets is provided; - the former informative Annex A has been turned into a clause in the standard.
Industrielle Systeme, Anlagen und Ausrüstungen und Industrieprodukte - Identifikation von Anschlüssen in Systemen
Systèmes industriels, installations et appareils, et produits industriels - Identification des bornes dans le cadre d'un système
La CEI 61666:2010 établit les principes généraux en vue de l'identification des bornes des objets à l'intérieur d'un système, applicables à tous les domaines techniques (par exemple l'ingénierie mécanique, l'ingénierie électrique, l'ingénierie de la construction, l'ingénierie des procédés). Ils peuvent être appliqués à des systèmes reposant sur des techniques différentes ou combinant plusieurs techniques. Les exigences relatives au marquage des désignations de bornes sur les produits ne font pas partie de la présente publication. Cette deuxième édition annule et remplace la première édition publiée en 1997. Cette édition constitue une révision technique. Cette édition inclut les modifications substantielles suivantes par rapport à l'édition précédente: - la terminologie utilisée dans la publication a été adaptée à celle utilisée dans la CEI 81346-1 Ed. 2; - une description plus complète des principes de désignation est fournie; - des exemples additionnels illustrant des désignations de bornes se rapportant à l'aspect de fonction et l'aspect d'emplacement sont fournis; - un exemple additionnel illustrant l'utilisation des ensembles de désignation de bornes est fourni; - l'ancienne Annexe A (informative) a été transformée en un article de la norme.
Industrijski sistemi, inštalacije, oprema in industrijski izdelki - Identifikacija (označevanje) priključkov v sistemu (IEC 61666:2010)
Ta mednarodni standard vzpostavlja splošna načela za identifikacijo priključkov objektov v sistemu, ki veljajo za vsa tehnična področja (na primer strojništvo, elektrotehniko, gradbeništvo, procesni inženiring). Uporabljajo se lahko za sisteme, osnovane na različnih tehnologijah ali za sisteme, ki združujejo več tehnologij. Zahteve za označevanje oznak priključkov na proizvodih niso del te objave.

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 responsi
