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 2.
The main task of technical committees is to prepare International Standards. 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction

This part of ISO 11064 establishes ergonomic requirements, recommendations and guidelines for the design
of workplaces in control centres.
All types of control centres are covered, including those for the process industry, transport and dispatching
systems or emergency services. Although this part of ISO 11064 is primarily intended for non-mobile control
centres, many of the principles are relevant to mobile centres such as those found on ships, locomotives and
aircraft.
User requirements are a central theme of this part of ISO 11064 and the processes described are designed to
take into account the needs of users at all stages. The overall strategy for dealing with the user requirements
is presented in ISO 11064-1. ISO 11064-2 provides guidance on the design and planning of the control room
in relation to its supporting areas. Requirements for the layout of the control room are covered by ISO 11064-
3. Displays and controls, human computer interaction and the physical working environment are presented in
ISO 11064-5 and ISO 11064-6. Evaluation principles are dealt with in ISO 11064-7.
The users of this standard are assumed to have some understanding of anthropometry, its use and limitations,
and its application in the context of control rooms. Where this understanding is in doubt it is recommended
that the advice of an expert is sought.
The ultimate beneficiaries of this part of ISO 11064 will be the operator within the control room and other
users. It is the needs of these users that provide the ergonomic requirements that are addressed by the
International Standards developers. Although it is unlikely that the end user will read this International
Standard, or even know of its existence, its application should provide the user with interfaces that are more
usable, and a working environment which is more consistent with operational demands and result in a solution
which will improve system performance and will minimize error and enhance productivity.

Ergonomic design of control centres — Part 4: Layout and
dimensions of workstations
1 Scope
This part of ISO 11064 specifies ergonomic principles, recommendations and requirements for the design of
workstations found in control centres. It covers workstation design with particular emphasis on layout and
dimensions. This standard covers primarily seated, visual-display-based workstations although control
workstations at which operators stand are also addressed. These different types of workstation are to be
found in applications such as transportation control, process control and security installations. Most of these
workstations now incorporate flat displays screens for the presentation of information.

[EN 614-1:2006, definition 3.18]
4 Initial workstation layout considerations
The starting point for control workstation design (shape and dimensions) is a list of work tasks and related
work characteristics. The human operator may need certain facilities, such as displays, input devices, and
communication equipment. Work space may also be required for special control-room-related tasks such as
paper work. For each task, a compilation of the requirements of the associated devices is needed. By taking
account of job designs, task zones are combined together into control workstation arrangements. The
grouping of control workstations into control room layouts is discussed in ISO 11064-2 and ISO 11064-3.
Requirements identified for each task zone are inputs for detailed engineering of workstations.
A systematic approach to designing workstations is presented in Figure 1. The sequence of stages involved in
this process may vary as a result of iterations and this may have an impact on the appropriate tasks, which
need to be undertaken at each stage.

5 Factors determining control workstation design
This clause is mainly concerned with control workstations with one or more visual displays, communication
tools and space for administrative functions and documentation.
5.1 General user considerations
th th
Workstations shall be designed to accommodate from the 5 to the 95 percentiles of dimensions of the
intended user population. When considering the user population, account shall be taken of the demographic
characteristics of the intended users including gender, age, ethnic backgrounds and disabilities.
Workstations shall be designed according to human capabilities, limitations and needs. Consequently, the
design shall take into consideration the physical characteristics of the user population including working
postures, visual and aural needs, reach envelopes and their collective influences on workstation layout and
dimensions.
5.1.1 User requirements
The layout and dimensioning of control workstations shall be governed by the anthropometric dimensions of
the user and any requirements for movement to accomplish their tasks. Anthropometric data are usually given
in terms of percentiles.
General anthropometric requirements are the following.
a) The percentile values referred to in this part of ISO 11064 shall be computed from the set of
anthropometric data of the expected user population.
th th
b) Control workstation dimensions shall accommodate at least a range from the 5 to the 95 percentile of
the user population.
c) The following anthropometric data shall be used to primarily determine the control workstation
dimensions:
th
 Reach envelope: 5 percentile of the user population, e.g. reach to critical equipment.
th
 Clearances: 95 percentile of the user population, e.g. clearances under worksurfaces.
The key anthropometric dimensions for consideration of a seated operator (in elevation) are shown in Figure
2. Figure 3 shows the anthropometric dimensions (in elevation) for consideration or a standing operator, and
Figure 4 shows the dimensions in plan view for a seated and standing operator. Any design solution selected
should not unnecessarily disadvantage members presenting extreme anthropometric dimensions of the user
population. Design parameters proposed should be checked against the relevant characteristics of the user
population.

Figure 2 — Illustration of the key anthropometric and workstation dimensions associated with a
seated control workstation in elevation
For standing vertical panels, Figure 3, controls should not be so low that the standing-tall user must stoop to reach down
to them.
Where no clothing allowances are specified in the anthropometric database, the dimensional effects of footwear and
clothing shall be considered.
The effects of different postures shall be considered.
th th
If it is impossible to cope with this range from the 5 percentile to the 95 with a fixed control workstation, an
adjustable workstation shall be considered.
It may be necessary to combine anthropometric data though caution should be exercised when doing this.
Usually the native anthropometric data set is based on naked subjects. Some data sources, however, include
clothing allowance on certain dimensions.
The workstation designers shall take account of the changes in eye position, relative to the location of
equipment and the view over the workstation, when different postures are adopted by the operator, Table 2.
Note: changing between the four postures of ‘bent forward’, ‘erect’, ‘reclined’ and ‘relaxed’ results in changes
in the vertical position of the eyes and their relative position relative to the front edge of the workstation,
Another allowance concerns the so-called slump factor (a correction made to measurements taken from an
erect posture). The slump factor is an attempt to simulate more natural and relaxed postures. In some
sources, this factor is included, in others this is not the case. Therefore, data sources should be checked
carefully before being applied.
Typically, control workstations will be operated by multiple users who might exhibit a range of anthropometric
features. Control workstation design and layout should take account of this variable user population.
th
Adjustable control workstations should be considered and accommodate at least a range from the 5
th
percentile to the 95 percentile of the determining body dimensions of the user population (see 7.2).
Adjustment devices should be easy and safe to use from a seated position.
NOTE Reliability is an important design feature when incorporating adjustability in workstations
