13、ies). 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 right to be represented on that committee. International organizations, governmental and

14、 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 Standards are drafted in accordance with the rules given in the ISO/IEC Directives,

15、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 an International Standard requires approval by at least 75 % of the member bodies cast

16、ing 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. In order to collect all requirements concerning basic principles for graphical symbols fo

17、r use on equipment, ISO/TC 145, Graphical symbols, and IEC/TC 3, Documentation and graphical symbols, agreed to prepare jointly all parts in this International Standard and to publish them under the general number 80416. For each of the individual parts of this series, only one of the two organizati

18、ons is responsible. Meanwhile, the technical committees have agreed that no modification will be made to International Standard 80416 except by mutual agreement. ISO 80416-4 was accordingly prepared jointly by Technical Committee ISO/TC 145, Graphical symbols, and Subcommittee 3C, Graphical symbols

19、for use on equipment, of Technical Committee IEC/TC 3, Information structures, documentation and graphical symbols. ISO 80416 consists of the following parts, under the general title Basic principles for graphical symbols for use on equipment: Part 2: Form and use of arrows Part 4: Guidelines for th

BS ISO/IEC 80416-4:2005v Introduction A graphical symbol is a visually perceptible figure us

21、ed to transmit information independently of language. Graphical symbols are used on equipment for a wide range of purposes. For such symbols, consistency in the design of families of symbols used in one location, or on similar equipment, helps users to understand the meaning of the symbols. Equally

22、important is the legibility of symbols when they are reduced to small dimensions. Thus, there is a need to standardize the principles for creating graphical symbols for use on equipment to ensure visual clarity and consistency, and thereby to improve recognition. This International Standard which is

23、 a multi-part standard, addresses the basic rules used to create graphical symbols for use on equipment, including line thicknesses, form and use of arrows, negation elements, and use of the basic pattern which serves as a guide for drawing symbols. These design principles are required to be used fo

24、r all graphical symbols for use on equipment, which are standardized in ISO 7000 and IEC 60417. Icons can reduce the apparent complexity of a software-user interface, making it easier to learn and use. This part of ISO 80416 provides guidelines for the adaptation of graphical symbols for use on scre

25、ens and displays (icons). This part of ISO 80416 is primarily concerned with the adaptation of graphical symbols for use as icons. However, the guidelines may also be used in the development of icons where suitable graphical symbols do not exist. Annex B contains additional guidelines for this purpo

26、se. Annex A provides examples of those symbols adapted as icons.

35、tically, e.g. 1 024 by 768 pixels. 4 Area of application 4.1 Screens and displays Graphical symbols used as icons can be presented upon a screen or display using a full or limited colour palette, or in monochrome. Icons are presented in varying sizes depending upon the specific implementation by the

36、 computer software and the attributes of the display technology, for example, the physical dimensions of the screen or display and the number of pixels available. There may be a need to modify the symbol original in order to ensure visual clarity provided that the original graphical impression is re

37、tained. 4.2 Supporting documentation Graphical symbols used as icons reproduced in supporting documentation should convey the same visual impression as those used on the screen or display. 4.3 International Standards If International Standards prepared by technical committees contain icons adapted f

38、rom graphical symbols with ISO 7000 or IEC 60417 registration numbers, each icon should be illustrated together with a reference to the registration number of the original graphical symbol. 5 Principles of implementation 5.1 General usage Icons are used widely in contemporary software systems that u

39、se graphical user interfaces. They can be static and used solely for visual identification/reinforcement of a textual description, or invoke a function or open an object when selected with a pointer. Icons can also be animated or dynamic and show the current status of the represented object. In cont

40、emporary operating systems (or “platforms”), icons have varying attributes and utilize different file types. The specific details of these attributes and file types are not addressed in this part of ISO 80416. BS ISO/IEC 80416-4:20053 5.2 Types of icons The following types of icons are addressed in

41、the different parts of ISO/IEC 11581: object icons (ISO/IEC 11581-2); pointer icons (ISO/IEC 11581-3); tool icons (ISO/IEC 11581-5); action icons (ISO/IEC 11581-6). NOTE 1 Action icons are also referred to as “tool bar“ icons. NOTE 2 Some graphical representations might be used in more than one icon

42、 type to provide similar functionality. For example, a printer icon could be used to describe the printer object, to start the print action, and to show the printer status or the ink level. 5.3 Relationship between graphical symbols and icons 5.3.1 Consistency When the same graphical symbol is used

43、both on equipment, in printed or engraved form, and presented on a screen or display as an icon, it is essential that the meaning of the graphical symbol is consistent across all areas of application. Internationally standardized graphical symbols should not be used with meanings other than those sp

44、ecified. 5.3.2 Adaptation of existing graphical symbols It is essential that new icons are adapted from existing internationally standardized graphical symbols, where a suitable graphical symbol exists with the same meaning. NOTE Examples of existing graphical symbols adapted as icons are given in A

45、nnex A. 5.4 Colour 5.4.1 Technical considerations Default colour palettes vary depending upon the operating system. When creating or adapting an icon, it is essential that the default colour palette of the operating system or environment in which the icon will be used is taken into account, so as to

46、 avoid unintended results. For screens or displays using cathode ray tubes (CRT) and liquid crystal display (LCD) panels, 8 bit (i.e. 256 colours) icons are commonly used. However, some devices, for example photocopiers and domestic appliances, can require 2 bit (monochrome) or 4 bit (16 colours) ic

47、ons. Within a 4 bit colour palette, additional colours can be created by mixing different colours spatially, i.e. by “checker-boarding” colours of similar tonal values. Only colours of similar tonal values should be spatially mixed (“dithered”). Mixing colours of contrasting tonal values will create

48、 visible “chequer” patterns. For web applications, a colour palette that can be displayed reliably using different browsers should be used. BS ISO/IEC 80416-4:20054 5.4.2 Use of colour It is important to consider all the icons to be used in order to create a harmonious visual impression. Unless ther

49、e is a specific reason, the same chromatic impression and balance between icons should be maintained. Because saturated colours are very dominating, they should be used sparingly and for a specific purpose, for example, for warning or change of status. Where an icon is derived from a standardized warning sign, colour fidelity should be maintained (see ISO 3864-1). Colour and grey outlines can be used to create a three-dimensional or highl
