18、010ISO 81714-1:2010(E) iv ISO 2010 All rights reservedForeword ISO (the International Organization 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.
19、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 take part in the work. ISO collaborates closely with the Internat
20、ional 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 main task of technical committees is to prepare International Standards. Draft International Stand
21、ards 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 possibility that some of the elements of this document may be the subjec
22、t of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 81714-1 was prepared jointly by Technical Committees ISO/TC 10, Technical product documentation, Subcommittee SC 10, Process plant documentation and tpd-symbols, and IEC/TC 3, Information structu
23、res, documentation and graphical symbols. The draft was circulated for voting to the national bodies of both ISO and IEC. This second edition of ISO 81714-1 cancels and replaces the first edition (ISO 81714-1:1999), which has been technically revised. ISO 81714 consists of the following parts, under
24、 the general title Design of graphical symbols for use in the technical documentation of products: Part 1: Basic rules IEC 81714 consists of the following parts, under the general title Design of graphical symbols for use in the technical documentation of products: Part 2: Specification for graphica

26、n of graphical symbols for use in the technical documentation of products Part 1: Basic rules 1 Scope This part of ISO 81714 specifies basic rules for the design of graphical symbols for use in the technical documentation of products, taking into account basic application needs. NOTE Supplementary r
27、equirements for graphical symbols used in advanced computer-aided design systems are specified in IEC 81714-2 and IEC 81714-3. 2 Normative references The following referenced documents are indispensable for the application of this document.

31、ISO 17724:20036, 31 NOTE 1 The graphical symbol may represent objects of interest, such as products, functions or requirements for manufacturing, quality control, etc. NOTE 2 A graphical symbol is not to be confused with the simplified representation of products which is normally drawn to scale and
32、which can look like a graphical symbol. BS EN ISO 81714-1:2010ISO 81714-1:2010(E) 2 ISO 2010 All rights reserved3.2 reference point origin of the coordinate system used in the description of all the graphical elements of the graphical symbol NOTE The reference point can be used for positioning and t
33、ransformation, e.g. by creation of a mirror image, rotation, and displacement. 3.3 symbol family set of graphical symbols with a common conception using graphical characteristics with specific meanings 3.4 connect node location on a graphical symbol intended for connection 3.5 terminal line line of
34、a graphical symbol ending at a connect node NOTE Most graphical symbols of non-electric character are not provided with terminal lines; most graphical symbols of electric character are provided with terminal lines. 3.6 text data in the form of characters, symbols, words, phrases, paragraphs, sentenc
35、es, tables, or other character arrangements, intended to convey a meaning, and whose interpretation is essentially based upon the readers knowledge of some natural language or artificial language ISO/IEC 2382-1:19933, 01.01.03 3.7 arc curved line with no inflection point 3.8 variant graphical symbol
36、s alternative graphical symbol design for a given referent ISO 17724:20036, 79 EXAMPLE An identified orientation of a graphical symbol with regard to the flow direction or transfer direction. NOTE A variant can be based on the rotation and/or creation of a mirror image of the corresponding symbol, t

38、hts reserved 35 Design of graphical symbols 5.1 Graphic representation Graphical symbols shall be designed to convey information concerning a function or a special requirement. This also applies when physical products are to be represented by graphical symbols. 5.2 Design procedure The design of gra
39、phical symbols shall follow the rules defined in Clause 6, taking into account: a) the description of what the graphical symbol is intended to represent; b) the requirements pertaining to presentation on paper or other solid media and in data processing; c) the analysis of the consequences when rota
40、ting, creating a mirror image or scaling (permitting different values of scaling factors on the x and y axes, if required); d) a requirement for functionally related graphical symbols to be designed as a symbol family; e) the normal application of the graphical symbol, e.g. for reference designation
41、 (see IEC 81346-113), technical data; f) if microcopying is intended, the additional requirements specified in ISO 6428. 6 Design principles 6.1 Shape The shape of a graphical symbol shall be: a) simple, in order to improve perceptibility and reproducibility; b) easily associated with its intended m
42、eaning, i.e. either self-evident, or easy to learn and to remember. Graphical symbols with the same shape representing different information should be avoided. Due to the limited number of graphical elements and the limited number of combinations of these elements, different meanings may have to be
43、assigned to graphical symbols having the same shape. In these cases, a separate graphical symbol shall be assigned to each meaning, provided with separate symbol identifiers (see 6.16). Graphical symbols with different shapes shall not represent the same information. For a human reader, the meaning
44、of a graphical symbol can normally be recognized because of the context of the document. If not, such graphical symbols shall be provided with supplementary information. BS EN ISO 81714-1:2010ISO 81714-1:2010(E) 4 ISO 2010 All rights reserved6.2 Operational state Graphical symbols having an element
45、representing a movable part in a product, e.g. a valving element in a directional control valve for fluid power and a contact in an electromechanical switching device, shall be designed in a position that corresponds to: a) the at-rest (unaffected) position for products with automatic return (e.g. a
46、 spring-loaded safety valve, a relay with spring return); b) the non-active position for products without automatic return (e.g. a shut-off valve in a closed position, an electromechanical switching device in open-circuit position). If operational states other than those specified in this part of IS
47、O 81714 are required, the relevant information should be given in the standard for graphical symbols and in the diagram where such operational state occurs. 6.3 Classes of graphical symbols Two classes of graphical symbols are recognized: a) class 1 graphical symbols providing basic information; b)
48、class 2 graphical symbols providing supplementary information. Graphical symbols belonging to class 2 should as far as possible be designed without relation to any specific context in order to make their application as broad as possible. These graphical symbols are intended to be used only together
49、with graphical symbols of class 1. Graphical symbols belonging to class 1, normally reduced in size, may also be used to provide supplementary information (see Figures 2 and 3). NOTE The graphical symbols providing the basic information for a pump as shown in Figure 2, and for an electrostatic microphone as shown in Figure 3, are used in each of the combinations as a graphical symbol giving supplementary information.
