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 member
bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the
subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 14738 was prepared by the ISO Technical Committee TC 159, Ergonomics,
Subcommittee SC 3, Anthropometry and biomechanics, in accordance with the Agreement on technical
cooperation between ISO and CEN (Vienna Agreement).
Throughout the text of this standard, read ".this European Standard." to mean ".this International
Standard″.
Annex A forms a normative part of this International Standard. Annex B is for information only.

Council
Directives has been removed.

Introduction
This International Standard is part of a set of ergonomics standards relating to anthropometry.
This International Standard describes how these ergonomics principles should be applied, using
anthropometric requirements for the design of workstations in the industries (machinery) and services.
NOTE: Utility company offering services for individuals or professionals all service companies were in
2015 destined for half to companies that integrate them into their production process as consumptions
Intermediate.
This concerns: trade, transport, accommodation and catering; Information and communication,
financial and insurance activities but also scientific and technical activities, administrative and Support
Services.
In addition, it is recommended that the postures and movements that are imposed by the machinery
design are evaluated as described in ISO 11226.
This International Standard has been prepared to be a harmonized standard in the sense of the last
Machinery Directive 2006-42 CE and associated EFTA regulations.
For work and workstations involving manual handling and repetitive tasks, designers are also advised
to refer to ISO technical report TR 12295 Handling Ergonomics (an ergonomics application document
for ISO standards on manual handling, ISO 11228-1, ISO 11228-2 and ISO 11228-3) and the Evaluation
of Static Working Postures (ISO 11226).
DRAFT INTERNATIONAL STANDARD ISO/DIS 14738:2020(E)
Safety of machinery — Anthropometric requirements for
the design of workstations for industries and services
1 Scope
This International Standard provides principles derived from the application of anthropometric data
to the design of workstations. It is based on ergonomics and currently available anthropometric
measurements.
This International Standard specifies the body's space requirements for normal operation of equipment
in sitting, sit-standing and standing positions. It includes space demands for maintenance, repairing
and cleaning work.
This International Standard does not give recommendations specifically for visual display terminal
workstations at machinery. For this purpose, ISO 9241-5 can be used in conjunction with this
International Standard.
Safety distances intended to prevent hazard zones being reached by upper and lower limbs are provided
in ISO 13857.
2 Normative references
This International Standard incorporates, by dated or undated reference, provisions from other
publications. These normative references are cited at the appropriate places in the text and the
publications are listed thereafter. For dated references, subsequent amendments to, or revisions of, any
of these publications apply to this International Standard only when incorporated in it by amendment
or revision. For undated references, the latest edition of the publication referred to applies (including
amendments).

3 Terms and definitions
3.1 Percentile (P)
Percentiles are the values of the variable that divide the population or the continuous variable into 100
equal groups by number (1% of the population).
NOTE Are considered as normal the values situated between (P5) and (P95).
3.2 95e percentile
It is the value such that 95% of the measured values are below and 5% are above.
3.3 Raised sitting position
It is dependent on technical necessities, tasks at varying levels of work or maintaining the level of vision
to that of the people standing. It has the same comfort advantages as sitting. On the other hand, it results
in a greater difficulty in manipulating and positioning the seating medium in front of a workstation.
NOTE It increases the risk of falling by sitting or getting up, as well as the risk of tripping over the base. The
footrest can be uncomfortable when climbing/descending the seat. The passage of the legs under the worktop
should not be prevented.
3.4 Sitting Position
The sitting station, or sitting position, is a rest station of the human being, in which the body rests on
the buttocks or the back of the thighs, with the trunk vertically.
3.5 Sit-standing position
The sit-standing position is suitable for situations where it is possible to adopt a fully seated position or
a position associating the sitting and standing position. It helps to support a portion of the body weight
and facilitates the return to a standing position.
3.6 Services
A service activity is characterized mainly by the provision of technical or intellectual capacity/delivery.
Unlike an industrial activity, it cannot be described by the characteristics of a material property
acquired by the customer. The line between material and intangible goods is also tenuous.
4 Task requirements
Design of workstations at machinery shall be based on an analysis of task requirements (see EN 614-1)
including at least the following element
