The work of preparing International St

10、andards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also

11、 take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committee

12、s is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possib

13、ility that some of the elements of this part of ISO 14617 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 14617-3 was prepared by Technical Committee ISO/TC 10, Technical product documentation, Subcommittee SC 10, Process plan

14、t documentation and tpd-symbols. ISO 14617 consists of the following parts, under the general title Graphical symbols for diagrams: Part 1: General information and indexes Part 2: Symbols having general application Part 3: Connections and related devices Part 4: Actuators and related devices Part 5:

15、 Measurement and control devices Part 6: Measurement and control functions Part 7: Basic mechanical components Part 8: Valves and dampers Part 9: Pumps, compressors and fans Part 10: Fluid power converters Part 11: Devices for heat transfer and heat engines Part 12: Devices for separating, purificat

16、ion and mixing Part 15: Installation diagrams and network maps Other parts are under preparation. BSISO146173:2002IS-71641 O3:(2002E) vIntroduction The purpose of ISO 14617 in its final form is the creation of a library of harmonized graphical symbols for diagrams used in technical applications. Thi

17、s work has been, and will be, performed in close cooperation between ISO and IEC. The ultimate result is intended to be published as a standard common to ISO and IEC, which their technical committees responsible for specific application fields can use in preparing International Standards and manuals

19、n joints, ISO ports, terminals, quick-release couplings and connectors, in diagrams. For the fundamental rules of creation and application of graphical symbols in diagrams, see ISO 81714-1. For an overview of ISO 14617, information on the creation and use of registration numbers for identifying grap

20、hical symbols used in diagrams, rules for the presentation and application of these symbols, and examples of their use and application, see ISO 14617-1. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this pa

21、rt of ISO 14617. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 14617 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indic

22、ated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

24、es of this part of ISO 14617, the following terms and definitions apply. NOTE 1 The list has been restricted to terms whose meaning is not obvious and which have not been defined elsewhere in an International Standard, or which have been defined in various ways in different standards. In preparing t

25、hese definitions, ISO and IEC standards on terminology have been consulted; see the references in parentheses. However, most of the definitions in those standards were prepared by different technical committees within a restricted scope. This means that many terms so defined have to be given more ge

26、neral or neutral definitions when applied in the context of graphical symbols. NOTE 2 In those cases where the same term has substantially different meanings in ISO and IEC, this is indicated beside the term by ISO or IEC and elsewhere in this part of ISO 14617 by a superscript, for example “port IS
