The w

9、ork 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 established has the right to be represented on that committee. International organizations, governmental and non-govern

10、mental, in liaison with ISO, also 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 2. The

11、 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. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

12、 Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 14617-1 was prepared by Technical Committee ISO/TC 10, Technical product documentation, Subcommi

18、phical symbols for diagrams Part 1: General information and indexes 1 Scope This part of ISO 14617 serves as an introduction to all the other parts. In particular, it gives information on the creation and use of registration numbers for identifying graphical symbols used in diagrams, rules for the p

19、resentation and application of these symbols, and examples of their use and application. It includes three indexes: an alphabetical index and an index of registration numbers both concerned uniquely with ISO 14617 and an index of cross-references to related items found in other International Standar

20、ds. For the fundamental rules of creation and application of graphical symbols in diagrams, see ISO 81714-1. 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,

21、 the latest edition of the referenced document (including any amendments) applies. ISO 81714-1:1999, Design of graphical symbols for use in the technical documentation of products Part 1: Basic rules 3 Terms and definitions For the purposes of this document, the following terms and definitions apply

22、. NOTE 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 these definitions, ISO and IEC standards on terminology have been consulte

23、d; 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 general or neutral definitions when applied in the context of graphical sym

ISO 81714-1 3.8 connecting line graphical symbol representing a functional connection, a mechanical link, a pipeline, a duct, or an electric connection IEC 61082-1 4 Arrangement of ISO 14617 4.1 Domains of application The complete ISO 14617 i

28、s to consist of a number of other parts in addition to those listed in the Foreword. Among the parts under preparation are ISO 14617-13, concerned with graphical symbols for material processing, and ISO 14617-14, concerned with the symbols representing devices for transport and handling of material.

29、 This part of ISO 14617 is an introduction to all the other parts. ISO 14617-2 to ISO 14617-6 cover graphical symbols for use in most technical fields. ISO 14617-7 to ISO 14617-12 cover those for use in all fields except the electrotechnical. ISO 14617-15 comprises graphical symbols for use in insta

ISO 14617-1:2005(E) ISO 2005 All rights reserved 3 4.2 Subdivision of parts Each part of ISO 14617 is divided into clauses that each deal with graphical symbols for a particular group of generic products or functions

31、. When appropriate, clauses are given subclauses, as follows using the example of Clause 7 from ISO 14617-2: Clause 7 Directions Subclause 7.1 Symbols of basic nature Subclause 7.2 Application rules for the symbols in 7.1 Subclause 7.3 Symbols giving supplementary information Subclause 7.4 Applicati

32、on rules for the symbols in 7.3 Subclause 7.5 Application examples Where certain subclauses are further subdivided, this has been done along the following lines. Take, for example, 4.3 in ISO 14617-2: Subclause 4.3 Symbols giving supplementary information Subclause 4.3.1 Input and output labels Subc

33、lause 4.3.2 General functions Subclause 4.3.3 Mathematical operations Subclause 4.3.4 Change of discrete state at specified values of a characteristic quantity Subclause 4.3.5 Logic negation, logic inversion, inputs and outputs for auxiliary power supply When a cross-reference is made to a particula

34、r graphical symbol or application rule or application example, its location is given within parentheses after the registration number of the symbol, rule or example. EXAMPLE 1 “See R101 (4.2.1)” directs the reader to application rule R101, located in subclause 4.2.1. When cross-referencing to anothe

35、r part, the part number is also included. EXAMPLE 2 A cross-reference to symbol 142 in ISO 14617-2 is given as “See 142 (2-4.3.2.28)”. 5 Registration numbers IMPORTANT A direct relationship does not necessarily exist between graphical symbols, application rules and application examples using registr

36、ation numbers that share the same numerals. For example, while graphical symbol 101 correlates to both application rule R101 and application example X101, it correlates as well to application examples X102 to X114; whereas symbol 114, to take just one other example, is unrelated to R114 and X114. 5.

37、1 Graphical symbol Each graphical symbol is assigned a unique registration number. In principle, this number is arbitrarily chosen. No information can be derived from it. The registration number will remain unchanged throughout the lifetime of the corresponding graphical symbol, including in future

38、revisions of this publication. If a graphical symbol is changed in the future, the registration number shall be supplemented with one or more characters. If the graphical symbol is substantially changed, it shall instead be given a new registration number. ISO 14617-1:2005(E) 4 ISO 2005 All rights r

39、eserved5.2 Application rule Each application rule has a registration number in the same way as the graphical symbols, except that the registration number starts with the letter R (e.g. R101). 5.3 Application example Each application example has a registration number in the same way as the graphical

40、symbols, except that the registration number starts with the letter X (e.g. X101). 6 Presentation of graphical symbols 6.1 General ISO 14617 establishes graphical symbols to be used in diagrams such as overview diagrams, flow diagrams and circuit diagrams. 6.2 Graphical symbols of same shape but dif

41、ferent meaning Graphical symbols having the same shape but different meanings have different registration numbers. This implies that it is possible to distinguish between same-shape graphical symbols in a CAD (computer-aided design) system, provided that each symbol has been recalled from a CAD libr

42、ary using the appropriate registration number. For a person reading a diagram, the intended meaning can normally be recognized by the context of the diagram. When this is not possible, graphical symbols having the same shape shall be provided with supplementary information. For examples, see the sym

43、bols for connections in ISO 14617-3 and the rules for adding symbols giving supplementary information such as application rule R402 in the same part. 6.3 Different forms of graphical symbols In some cases, different forms of a graphical symbol can occur. These different forms are given separate regi

44、stration numbers. The primary reason for having two or more forms for the same symbolization is that they convey differing amounts of information. Symbols having different forms and differing amounts of information (e.g. those for use in overview diagrams and those for use in circuit diagrams) are m

45、arked Form 1, Form 2, etc. This marking is also used in some cases where the different forms contain the same amount of information, but where more than one form is justified because of different application methods in the rules for preparing diagrams. 6.4 Dimensions of graphical symbols The graphic

46、al symbols in ISO 14617 have been designed in accordance with the rules given in ISO 81714-1. The module size M = 2,5 mm has been used. For small graphical symbols, the symbol is shown double its normal size, applying the same module and the same line width. Such symbols are marked “200 %”. For the

47、auxiliary grid system defined in ISO 81714-1, the module 0,25 M has been used. 6.5 Descriptions In those cases where ISO and IEC have the same term for different items, the term has been provided with ISO and IEC superscripts, for example, line ISOand line IEC .

48、ts reserved 5 7 Application rules and examples The application rules give information on how to design composite symbols and how to apply the graphical symbols in a diagram. The application examples are to be regarded as guidelines. In order to facilitate their use, the application examples are acco

49、mpanied by information on which graphical symbols have been used to compose the examples shown. EXAMPLE “101, 123” in 2-4.5.8 signifies that the example X108 is built up from graphical symbols 101 and 123. 8 Use of graphical symbols 8.1 Choice of graphical symbols Rules for the choice of graphical symbols are given in the standards for the preparation of diagrams. 8.2 Dimensions of graphical symbols Symbols may be increased in size, for example, in order to allow all terminals to be represente
