Foreword
ISO (the International Organization 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 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. 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, Part 3.
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 casting a vote.
International Standard ISO 9241-6 was prepared by Technical Committee ISO/TC 159, Ergonomics, Sub-
Committee SC 4, Ergonomics of human-system interaction, Working Group WG 3, Control, workplace and
environmental requirements.
ISO 9241 consists of the following parts, under the general title Ergonomic requirements for office work with visual
display terminals (VDTs):
 Part 1: General introduction
 Part 2: Guidance on task requirements
 Part 3: Visual display requirements

Introduction
This part of ISO 9241 applies to work systems as defined in ISO 6385 with visual display terminals (VDTs) as
described in ISO 9241-1. Office work with VDTs can be performed in various environments. These environments
can influence both the comfort and performance of the user. In addition, the work environment can be influenced by
specific characteristics of the VDTs and related equipment (for example, printers, computers).
This part of ISO 9241 has been prepared to give guidance on the determination of environmental conditions which
enhance user comfort and performance. Enhancing the interaction between users and environments often requires
a well-balanced trade-off. For this reason, this part of ISO 9241 provides guiding principles as generic goals, basic
aspects for each item (for example, lighting, noise) and gives guidance on developing integrated solutions under
given circumstances (for example, methods of controlling the acoustic environment for a given task and a given
environment).

Ergonomic requirements for office work with visual display
terminals (VDTs) —
Part 6:
Guidance on the work environment
1 Scope
This part of ISO 9241 provides guidance on basic principles for the ergonomic design of the work environment and
the workstation, taking into account lighting, effects of noise and mechanical vibrations, electrical and magnetic
fields and static electricity, thermal environment, space organization and workplace layout.
This part of ISO 9241 is applicable to the work environment and workstation in those work systems where a visual
display terminal (VDT) is used for office work.
However, this part of ISO 9241 does not specify the technical characteristics of the equipment needed to satisfy
those equipment-related guidelines associated with the work environment.
