25、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

26、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

27、rnational 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. Publica

28、tion as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

32、of those requirements to different display technologies, application areas and environmental conditions including test methods and pass/fail criteria is specified in ISO 9241-307.

42、 9241 addresses a large range of technologies, tasks and environments. ISO 9241 was originally developed as a seventeen-part International Standard on the ergonomics requirements for office work with visual display terminals. As part of the standards review process, a major restructuring of ISO 9241

43、 was agreed to broaden its scope, to incorporate other relevant standards and to make it more usable. The general title of the revised ISO 9241, “Ergonomics of human-system interaction”, reflects these changes and aligns the standard with the overall title and scope of Technical Committee ISO/TC 159

44、, Subcommittee SC 4. The revised multipart standard is structured as series of standards numbered in the “hundreds”: the 100 series deals with software interfaces, the 200 series with human-centred design, the 300 series with visual displays, the 400 series with physical input devices, and so on. Se

45、e Annex A for an overview of the entire ISO 9241 series. BS EN ISO 9241-303:2011INTERNATIONAL STANDARD ISO 9241-303:2011(E) ISO 2011 All rights reserved 1Ergonomics of human-system interaction Part 303: Requirements for electronic visual displays 1 Scope This part of ISO 9241 establishes image-quali

46、ty requirements, as well as providing guidelines, for electronic visual displays. These are given in the form of generic independent of technology, task and environment performance specifications and recommendations that will ensure effective and comfortable viewing conditions for users with normal

47、or adjusted-to-normal eyesight. This part of ISO 9241 does not address issues of accessibility for people with disabilities. However, it does take into account aspects of the eyesight of older people and could be of value to people dealing with issues of visual impairment in certain cases: the speci

48、fication of essential characteristics for normal viewing can be used to gauge the severity of different visual abnormalities so that appropriate solutions can be identified. NOTE In addition to the Bibliography, Annex F gives a selected bibliography of documents addressing the needs of people with d

49、isabilities, including people with poor, deteriorating or no eyesight. 2 Normative references The following referenced documents are indispensable for the application of this document.
