28、ord IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a techni
29、cal 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. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of e
30、lectrotechnical standardization. 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 %ofthe member bodies casting a vote. International Standard IS0 9241-1 was prep
31、ared by Technical Committee ISO/TC 159, Eu;qonomics, Subcommittee SC 4, Eu;qonomics ofhuman system interaction. This second edition cancels and replaces the first edition (IS0 9241-1: 1992), which has been technically revised. IS0 9241 consists ofthe following parts, under the general title Ergonomi
32、c requirements for ofice work with visual display terminals (VDTs): -Part I: General intraduction; -Part 2: Guidance on task requirements; -Part 3: Visual display requirements; -Part 4: Keyboard requirements; -Part 5: Wwhtation layout andpostural requirements; -Part 6: Environmental requirements; -P

Annex A of this part of IS0 9241 is for information only. . 111 O BSI 24 July 2002 iv blank EN IS0 9241-111997 Intro duct i on One of the main concerns of ergonomics is to ensure that products and sy
35、stems are fit for human use. In general this involves matching the design of products or systems, including displays, input devices, software, workplace, working environment and tasks, to the characteristics, capabilities and limitations of potential users. Improving the ergonomic properties of syst
36、ems will improve performance, reduce errors and discomfort, and minimize health and safety risks. Failure to take account of human capabilities is wasteful, will reduce efficiency and result in boring, tedious work. In practice, all users ofproducts or systems are different; it is important to under
37、stand in what ways they vary and to quanti the variation so that account can be taken ofit in design. Both hardware and software can be used for many different tasks, and in a variety ofworking environments, and it is also important to take these factors intoconsideration in design. Good ergonomic d
38、esign is important in any product or system designed for human use. It is especially important when: -use is intensive; -accuracy or speed of the users performance is critical; -user acceptance is critical. Work with visual display terminals (VDTs) is often both intensive and a significant part of m
39、any office workersjobs. The characteristics ofboth hardware and software can substantially affect the users performance. Increasingly, users, their representatives and managers are concerned with ensuring that work with VDTs is designed to appropriate standards. What is appropriate in one set ofcirc
40、umstances may be inappropriate in a different context; when using VDT ergonomics standards it is important to recognize that the potential range of application is very broad. Therefore ergonomics standards often take the form of recommendations, or requirements, which are conditional upon certain de
41、fined circumstances. 1 Scope This part ofISO 9241: -introduces the multipart standard on ergonomic requirements for the use of visual display terminals for office tasks; -provides guidelines for a user-performance approach; -gives an overview of all parts ofISO 9241 currently published and of the an
42、ticipated content ofthose in preparation; -provides some guidance on how to use IS0 9241; -describes how conformance to IS0 9241 should be reported. For the purposes ofISO 9241, office tasks are taken to include a wide range ofgeneric text and data processing tasks. Due to the similarity of these ta
43、sks to tasks performed in other environments, e.g. medical, scientific, telecommunications, control rooms and public access, many of the requirements in IS0 9241 are appropriate to these environments as well. IS0 9241 does not cover electrical safety ofVDTs. This is covered by IEC 60950 NOTE human-c
44、entred design for interactive systems is provided in IS0 13407. The ergonomic requirements of flat panel displays are covered in IS0 13406-1 and IS0 13406-2.

Ergonomic design enhances the ability ofVDT users to operate display scree
49、n equipment safely, healthily, effectively, efficiently and comfortably. This is achieved by careful design ofthe VDTs, the workplaces and working environments in which they are used, and the way the VDT work is organized, managed and performed. In practice, these different aspects may be the responsibility of a number of different people or organizations. IS0 9241 is intended to help designers and manufacturers to develop ergonomically sound visual display terminals and software systems. IS0 9241 is also relevant to purchasers who wish to specieVDT systems for u
