20、andardization) 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 has the rig

21、ht 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. International

22、 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 Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as a

23、n 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 subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO

24、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 structures, documentation and graphical symbols. The draft was circulated for voting to the national bodies of b

28、raphical 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 require

29、ments 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.

33、724:20036, 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 which

34、can look like a graphical symbol.

35、l elements of the graphical symbol NOTE The reference point can be used for positioning and transformation, 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 c

36、onnect node location on a graphical symbol intended for connection 3.5 terminal line line of 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

37、 lines. 3.6 text data in the form of characters, symbols, words, phrases, paragraphs, sentences, 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 238

NOTE A variant

39、can be based on the rotation and/or creation of a mirror image of the corresponding symbol, together with possibly other modifications such as relocation of inputs and outputs and reorientation of text. 4 Markers In this part of ISO 81714, the marker shown in Figure 1 is used to illustrate positions

40、 of connect nodes.

41、o 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 graphical symbols shall follow the rules defined in Clause 6, taking into account: a) the description of what t

42、he 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 rotating, creating a mirror image or scaling (permitting different values of scaling factors on the x and y axes

43、, 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 (see IEC 81346-113), technical data; f) if microcopying is intended, the additional requirements specified

44、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 meaning, i.e. either self-evident, or easy to learn and to remember. Graphical symbols with the same shape re

45、presenting 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 assigned to graphical symbols having the same shape. In these cases, a separate graphical symbol shall be as

46、signed 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 of a graphical symbol can normally be recognized because of the context of the document. If not, such graphi

47、cal symbols shall be provided with supplementary information.

48、ing 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 spring-l

49、oaded 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 ISO 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 r
