25、1346-2 IEC:2009 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ INDUSTRIAL SYSTEMS, INSTALLATIONS AND EQUIPMENT AND INDUSTRIAL PRODUCTS STRUCTURING PRINCIPLES AND REFERENCE DESIGNATIONS Part 2: Classification of objects and codes for classes FOREWORD 1) The International Electrotechnical Commission (IEC

26、) 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

27、 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

28、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 con

29、ditions 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 Na

30、tional 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

31、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 I

32、EC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should

33、 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

34、 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 th

35、e 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.

36、 International Standard IEC 81346-2 has been prepared by IEC technical committee 3: Information structures, documentation and graphical symbols and ISO technical committee 10: Technical product documentation. It is published as a double logo standard. This edition cancels and replaces the first edit

37、ion of IEC 61346-2, published in 2000 and the first edition of IEC/PAS 62400, published in 2005. This edition includes the following technical changes with respect to IEC 61346-2 Ed.1: all rules concerning the application of letter codes have been removed as these should be included in another publi

38、cation dealing with the application of letter codes within reference designations; and, with respect to IEC/PAS 62400 Ed.1: 81346-2 IEC:2009 5 the definitions of the sub-classes have been reviewed and made consistent; the basis for the sub-classification is indicated; some new subclasses for class B

39、 and class P have been added; the table of terms sorted according to the two-letter code has been removed; The text of this standard is based on the following documents: FDIS Report on voting 3/945/FDIS 3/957RVDFull information on the voting for the approval of this standard can be found in the repo

40、rt on voting indicated in the above table. In ISO, the standard has been approved by 12 members out of 13 having cast a vote. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of IEC 81346 series, formerly IEC 61346 series, published under the g

41、eneral title Industrial systems, installations and equipment and industrial products Structuring principles and reference designations, can be found on the IEC website. Future standards in this series will carry the new general number 81346. Numbers of existing standards in this series will be updat

42、ed at the time of the next edition. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch” in the data related to the specific publication. At this date, the publication will

43、be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 81346-2 IEC:2009 INTRODUCTION 0.1 General The aim of this part of IEC 81346 is to establish classification schemes for objects with associated letter codes which can be applied throughout all technical areas, e.g. electrical, me

44、chanical and civil engineering as well as all branches of industry, e.g. energy, chemical industry, building technology, shipbuilding and marine technology. The letter codes are intended for use with the rules for the construction of reference designations in accordance with IEC 81346-1. Annex A ill

45、ustrates how objects may be classified according to their intended purpose or task related to a generic process. Annex B illustrates how objects may be classified according to their position in an infrastructure. 0.2 Basic requirements for this standard The basic requirements were developed during t

46、he preparation of IEC 61346-2 Ed. 1, and accepted by vote by the national committees. NOTE These basic requirements concern the development of the letter code classification system in this standard and not its application. They are therefore not normative vis-vis the application of this standard. (1

47、) Letter codes shall be based on a classification scheme. (2) A classification scheme is the set of definitions for the types of objects (for example, a classification scheme for function types containing the definition of the different function types of objects). (3) A classification scheme shall a

48、llow for hierarchical classification of types of objects, i.e. subclasses and superclasses. (4) A letter code for a type of object shall be independent of the actual position of the instances of that type of object in a system. (5) Distinct classes shall be defined on each level of the classificatio

49、n scheme. (6) The definitions of the classes of a particular level within a classification scheme shall have a common basis (for example, a classification scheme that, on one level, classifies objects according to colour shall not contain classes that classify objects by shape). The basis, however, may vary from one level to another. (7) A letter code should indicate the type of object and not an
