25、 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 ot
26、her 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
27、 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 condition
28、s 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
29、 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
30、 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 Pub
31、lication 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 i
32、s 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 te
33、chnical 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 I
34、EC 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 sub
35、ject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61666 has been prepared by IEC technical committee 3: Information structures, documentation and graphical symbols This second edition cancels and replaces the first edit
36、ion of IEC 61666 published in 1997. This edition constitutes a technical revision. This edition 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 descrip
37、tion 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
38、into a clause in the standard. 4 61666 IEC:2010 The text of this standard is based on the following documents: FDIS Report on voting 3/1001/FDIS 3/1008/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publica
39、tion has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this
40、 date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 61666 IEC:2010 5 INDUSTRIAL SYSTEMS, INSTALLATIONS AND EQUIPMENT AND INDUSTRIAL PRODUCTS IDENTIFICATION OF TERMINALS WITHIN A SYSTEM 1 Scope This International Standard establishes general principles fo
41、r 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 t
42、echnologies. Requirements for marking of terminal designations on products are not part of this publication. NOTE The standard is based on the general principles for the structuring of systems including structuring of the information about systems, established in the International Standard ISO/IEC 8
43、1346 series, published jointly by IEC and ISO. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any
44、amendments) applies. IEC 60417, Graphical symbols for use on equipment IEC 60445, Basic and safety principles for man-machine interface, marking and identification Identification of equipment terminals and conductor terminations IEC 60757, Code for designation of colours IEC 61082-1:2006, Preparatio

46、s Part 3: Classification of connect nodes, networks and their encoding 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 object entity treated in a process of development, implementation, usage and disposal NOTE 1 The object may refer to a phys
47、ical or non-physical “thing”, i.e. anything that might exist, exists or did exist. NOTE 2 The object has information associated to it IEC 81346-1, definition 3.1 6 61666 IEC:2010 3.2 system set of interrelated objects considered in a defined context as a whole and separated from their environment NO
48、TE 1 A system is generally defined with the view of achieving a given objective, e.g. by performing a definite function. NOTE 2 Elements of a system may be natural or man-made material objects, as well as modes of thinking and the results thereof (e.g. forms of organisation, mathematical methods, pr
49、ogramming languages). NOTE 3 The system is considered to be separated from the environment and from the other external systems by an imaginary surface, which cuts the links between them and the system. NOTE 4 The term “system” should be qualified when it is not clear from the context to what it refers, e.g. control system, colorimetric system, system of units, transmission system. NOT
