The work of preparing International S
12、tandards 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, als
13、o 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 committe
14、es 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 possi
15、bility 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 14617-2 was prepared by Technical Committee ISO/TC 10, Technical product documentation, Subcommittee SC 10, Process pla
16、nt 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
17、: 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, purifica

19、rm is the creation of a library of harmonized graphical symbols for diagrams used in technical applications. This 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
20、 committees responsible for specific application fields can use in preparing International Standards and manuals.

22、mplete symbols representing specific products and functions 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 graphical symbol
23、s 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 part of ISO 14

NOTE The list has been restricted
29、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 these definitions, ISO and IEC standards on terminology have been consulted; see the references in parentheses
30、. 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 general or neutral definitions when applied in the context of graphical symbols. 3.1 complex device device cons
