The work of preparing International Standards is normally carried out through IS0 technic
31、al 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 part in the work. IS0 collab- orates closely
32、 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 Standard requires approval by at least 75 %
33、of the member bodies casting a vote. International Standard IS0 9241 -5 was prepared by Technical Committee lSO/TC 159, Ergonomics, Sub-committee SC 4, Ergonomics of human- system interaction, Working Group WG 3, Control, workplace and environmental requirements.

37、omote and enhance performance and comfort while minimizing risks to users safety and health. Users of visual display terminais (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 accommodate
38、such usage can encourage movement, promote comfort and reduce physical, mental and visual problems. This pari of I!SO 9241 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.
