9、ganization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been establ
10、ished has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardizati
11、on. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
12、 Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility 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 al
13、l such patent rights. ISO 14617-7 was prepared by Technical Committee ISO/TC 10, Technical product documentation, Subcommittee SC 10, Process plant documentation and tpd-symbols. ISO 14617 consists of the following parts, under the general title Graphical symbols for diagrams: Part 1: General inform
14、ation and indexes Part 2: Symbols having general application Part 3: Connections and related devices Part 4: Actuators and related devices Part 5: Measurement and control devices Part 6: Measurement and control functions Part 7: Basic mechanical components Part 8: Valves and dampers Part 9: Pumps, c
15、ompressors and fans Part 10: Fluid power converters Part 11: Devices for heat transfer and heat engines Part 12: Devices for separating, purification and mixing Part 15: Installation diagrams and network maps Other parts are under preparation. BSISO146177:2002IS-71641 O7:(2002E) vIntroduction The pu
16、rpose of ISO 14617 in its final form 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
17、ISO and IEC, which their technical committees responsible for specific application fields can use in preparing International Standards and manuals.

18、is part of ISO 14617 specifies graphical symbols in diagrams for mechanical elements such as weights, springs, clutches and brakes, pipe and duct elements such as restrictors, nozzles and air vents, and devices for storage such as tanks, pressure vessels and gas bottles. For the fundamental rules of
19、 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 symbols used in diagrams, rules for the presentation and application of these symbols, and examples of thei

For dated references, subsequent amendments to, or revisions of, any of these publications do no

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

23、 use in the technical documentation of products Part 1: Basic rules 3 Terms and definitions For the purposes of this part of ISO 14617, the following terms and definitions apply. NOTE The list has been restricted to terms whose meaning is not obvious and which have not been defined elsewhere in an I
24、nternational 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. However, most of the definitions in those standards were prepared by different techni
25、cal 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.
