NOTE Supplementary requirements for graphical symbols used in advanced computer-aided des

For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (inc

30、 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 graphical symbol visually perceptible figure with a particular meaning used to transmit information independently of language ISO 17724:20036, 31 NOTE 1 The graphical symbol may represent objects
31、 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 can look like a graphical symbol. DIN EN ISO 81714-1:2010-11 EN
32、 ISO 81714-1:2010 (E) 4 3.2 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 transformation, e.g. by creation of a mirror image, rotation, and displacement. 3.3 symbo
33、l 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 a graphical symbol ending at a connect node NOTE Most graphical symbols of non-electric
34、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, sentences, tables, or other character arrangements, intended to convey a meaning, and whose int
35、erpretation 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 symbols alternative graphical symbol design for a given referent ISO 17724:20036, 79 EXAMPLE A
36、n 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, together with possibly other modifications such as relocation of inputs and outputs and r
37、eorientation of text. 4 Markers In this part of ISO 81714, the marker shown in Figure 1 is used to illustrate positions of connect nodes. Figure 1 Marker DIN EN ISO 81714-1:2010-11 EN ISO 81714-1:2010 (E) 5 5 Design of graphical symbols 5.1 Graphic representation Graphical symbols shall be designed
38、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 graphical symbols shall follow the rules defined in Clause 6, taking into account: a) the description of what
39、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 rotating, creating a mirror image or scaling (permitting different values of scaling factors on the x and y axe
40、s, 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
41、 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 r
42、epresenting 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 a
43、ssigned 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 graph
44、ical symbols shall be provided with supplementary information. DIN EN ISO 81714-1:2010-11 EN ISO 81714-1:2010 (E) 6 6.2 Operational state Graphical symbols having an element representing a movable part in a product, e.g. a valving element in a directional control valve for fluid power and a contact
45、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-loaded safety valve, a relay with spring return); b) the non-active position for products without automatic return (e.
46、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
47、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) class 2 graphical symbols providing supplementary information. Graphical symbols belonging to class 2 should as far as possibl
48、e 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 with graphical symbols of class 1. Graphical symbols belonging to class 1, normally reduced in size, may also be used to provi
49、de 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. Figure 2 Pumping system Figure 3 Electrostatic microphone 6.4 Combination of graphical symbols 6.4.1 General Graphical symbols may be combined to form a new graphical symbol.
