The work of preparing International Standard

27、s 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 non-governmental, in liaison with ISO, also take

28、part in the work. ISO collaborates closely with the International Electrotechnical Commission(IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Sta

29、ndard requires approval by at least75% of the member bodies casting a vote. International Standard ISO9241-5 was prepared by Technical Committee ISO/TC159, Ergonomics, Sub-committee SC4, Ergonomics of human-system interaction, Working Group WG3, Control, workplace and environmental requirements.

Annex A of this part of ISO9241 is for information only.iv blankEN ISO9241-5:1999 BSI 04-2000 1 Introduction The purpose of this part of ISO9241 is

33、to promote and enhance performance and comfort while minimizing risks to users safety and health. Users of visual display terminals(VDTs) in office work typically adopt a range of postures(seated with leaning, upright or reclining torso, standing or a combination of both). Workplaces which accommoda

34、te such usage can encourage movement, promote comfort and reduce physical, mental and visual problems. This part of ISO9241 is intended for use by product and workstation designers and implementers. While drafting the text, the concept concerning the Frankfurt Plane was discussed but not included. T

35、he concept will be considered in a revision of this part of ISO9241 in due course. 1 Scope This part of ISO9241 specifies ergonomic guiding principles which apply to the user requirements, design, and procurement of workstation equipment for office tasks using VDTs. In particular, the general princi

36、ples and requirements specified in this part of ISO9241 apply to the standards specifying technical design of furniture and equipment constituting the workplace. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this par

37、t of ISO9241. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO9241 are encouraged to investigate the possibility applying the most recent editions of the standards indicated below.
