Foreword
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 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 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 Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard IS0 9241-I was prepared by Technical Committee ISO/TC 159, Ergonomics, Subcommittee
SC 4, Ergonomics of human system interaction.
This second edition cancels and replaces the first edition (IS0 9241-I :I 992), which has been technically revised.
IS0 9241 consists of the following parts, under the general title Ergonomic requirements for office work with visual
display terminals (VD Ts):
- Part I: General introduction
- Part 2: Guidance on task requirements
- Part 3: Visual display requirements
- Part 4: Keyboard requirements
- Part 5: Wo:rkstation layout and postural requirements

Introduction
One of the main concerns of ergonomics is to ensure that products and systems 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 systems 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 of products or systems are different; it is important to understand in what ways they vary and to
quantify the variation so that account can be taken of it in design. Both hardware and software can be used for
many different tasks, and in a variety of working environments, and it is also important to take these factors into
consideration in design. Good ergonomic design is important in any product or system designed for human use. It
is especially important when :
- use is intensive;
accuracy or speed of the user’s performance is critical;
user acceptance is critical.
Work with visual display terminals (VDTs) is often both intensive and a significant part of many office workers’ jobs.
The characteristics of both hardware and software can substantially affect the user’s 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 of circumstances 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 defined circumstances.

Ergonomic requirements for office work with visual display
terminals (VDTs) -
Part 1:
General introduction
1 Scope
This part of IS0 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 of IS0 9241 currently published and of the anticipated content of those in
preparation;
- provides some guidance on how to use IS0 9241;
- describes how conformance to IS0 9241 should be reported.
For the purposes of IS0 9241, office tasks are taken to include a wide range of generic text and data processing
tasks. Due to the similarity of these tasks 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 of VDTs. This is covered by IEC 950.
- The ergonomic requirements of flat panel displays are covered in IS0 13406-I and IS0 13406-2. More extensive
NOTE
guidance on human-centred design for interactive systems is provided in IS0 13407.

4 General introduction to IS0 9241
4.1 Purpose and intended users
IS0 9241 establishes ergonomic requirements for office work with VDTs. Ergonomic design enhances the ability of
VDT users to operate display screen equipment safely, healthily, effectively, efficiently and comfortably. This is
achieved by careful design of the 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 specify VDT systems for use in their
own organizations, and to those who wish to
