10、on 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 established ha
11、s 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 standardization. Inte
12、rnational 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. Publica
13、tion 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 all such p
14、atent rights. ISO 14617-1 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 information an
15、d 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, compresso
16、rs 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. Annexes A, B and C of this part of ISO 14617 are for information
17、 only. BSISO146171:2002IS-71641 O1:(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. This work has been, and will be, performed in close cooperation between ISO and IEC. The ultim
18、ate 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、ols 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 presentation
20、 and application of these symbols, and examples of their use and application. It includes three indexes: an alphabetic index and an index of registration numbers, both concerned uniquely with ISO 14617-2 to ISO 14617-12, and an index of cross-references to related items found in other International
21、Standards. For the fundamental rules of creation and application of graphical symbols in diagrams, see ISO 81714-1. 2 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this part of ISO 14617. For dated references,
22、 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 edition of the normative document indicated below. For undated references, the
23、latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. 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 pur
24、poses 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 International Standard, or which have been defined in various ways in different standards. In preparing
25、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 technical committees within a restricted scope. This means that many terms so defined have to be given more g
26、eneral or neutral definitions when applied in the context of graphical symbols. 3.1 function activity proper to anything, mode of action by which it fulfils its purpose EXAMPLE To measure, to control, to indicate. 3.2 product thing produced by natural process or manufacture; result EXAMPLE An elemen
27、t, a component or a device. BSISO146171:2002IS-71641 O1:(2002E) 2 3.3 component constituent part of equipment that cannot be physically divided into smaller parts without losing its character IEC 60050-131 3.4 device assembly of components to perform a required function EXAMPLE An actuating device,
28、a centrifuge. IEC 60050-151 3.5 element part of a component EXAMPLE A filter element in a filter, a contact in an electromechanical relay. 3.6 graphical symbol visually perceptible figure used to transmit information independently of language ISO 81714-1 3.7 terminal line line of a graphical symbol
29、ending at a connect node NOTE A connect node is a location on a graphical symbol intended for connection (ISO 81714-1). 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
30、 ISO 14617 4.1 Domains of application The complete ISO 14617 is 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 symbol
31、s representing devices for transport and handling of material. 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 electrotechni
32、cal. ISO 14617-15 comprises graphical symbols for use in installation diagrams and on network maps for pipelines, ducts and electric connections. BSISO146171:2002IS-71641 O1:(2002E) 34.2 Subdivision of parts Each part of ISO 14617 is divided into clauses that each deal with graphical symbols for a p
33、articular group of generic products or functions. 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 s
34、upplementary information Subclause 7.4 Application 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 informat
35、ion Subclause 4.3.1 Input and output labels Subclause 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 supp
36、ly When a cross-reference is made to a particular 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 s
37、ubclause 4.2.1. When cross-referencing to another 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, applicat
38、ion rules and application examples using registration 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
39、other example, is unrelated to R114 and X114. 5.1 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 corr
40、esponding graphical symbol, including in future 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 num
41、ber. BSISO146171:2002IS-71641 O1:(2002E) 4 5.2 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 numb
42、er in the same way as the graphical 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 Gra
43、phical symbols of same shape but different 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 symb
44、ol has been recalled from a CAD library 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 in
45、formation. For examples, see the symbols 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 dif
46、ferent forms are given separate registration 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 thos
47、e for use in circuit diagrams) are marked 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 Dimensi
48、ons of graphical symbols The graphical 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
49、symbols are marked “200 %”. For the 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 .
