PREPARATION OF INSTRUCTIONS FOR USE –
STRUCTURING, CONTENT AND PRESENTATION –

Part 1: General principles and detailed requirements

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 82079-1 has been prepared by IEC technical committee 3:
Information structures, documentation and graphical symbols, in liaison with ISO technical
committee 10: Technical product documentation, and with the ISO Committee on consumer
policy (COPOLCO).
This first edition cancels and replaces IEC 62079 published in 2001.It constitutes a technical
revision.
The text of this standard is based on the following documents:
FDIS Report on voting
3/1093/FDIS 3/1103/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.

82079-1 © IEC:2012 – 7 –
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC Web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a
colour printer.

PREPARATION OF INSTRUCTIONS FOR USE –
STRUCTURING, CONTENT AND PRESENTATION –

Part 1: General principles and detailed requirements

1 Scope
This part of IEC 82079 provides general principles and detailed requirements for the design
and formulation of all types of instructions for use that will be necessary or helpful for users of
products of all kinds, ranging from a tin of paint to large or highly complex products, such as
large industrial machinery, turnkey based plants or buildings.
NOTE The term "product" as defined in 3.29 relates to consumer, non-consumer, electrical, electronic,
electromechanical, mechanical and other products.
This part is intended for all parties involved in the preparation of instructions for use, for
example:
• Suppliers, technical writers, technical illustrators, software designers, translators or other
people engaged in the work of conceiving and drafting such instructions for use;
This part of IEC 82079 does not specify a fixed amount of documentation that has to be
delivered with a product. This is obviously not possible because this part is applicable to all
kinds of products. The amount of documentation required, will depend on the nature of the
product, its complexity and the skills of the intended users.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For

4 Principles
4.1 Provision of instructions for use
4.1.1 General
The level of description and details of information shall be adapted to the knowledge of target
group(s). Instructions for use shall ensure the completeness of relevant information at a
sufficient level of detail based on the ascertained needs of the target group.
4.1.2 Instructions for use are part of the product
A product shall be accompanied by instructions for use which promote its intended use and
contain all information that a user needs to know when using the product. Where instructions
for use comprise more than one document, these shall be arranged in a meaningful and
organized system and support navigation. The way in which third party documents are
integrated shall be based on customer requirements and user needs.
Instructions for use shall when followed by the user contribute to reducing the risk of injury or
illness to people or animals, and risks of damage, malfunction or inefficient operation of the
product. Instructions for use cannot compensate for design deficiencies or missing safety
systems (see ISO/IEC Guide 37).
4.1.3 Consistency of information
All information in instructions for use shall be consistent within itself, with the product and
with all other information relating to the same product issued by the supplier, such as
advertising or packaging and any warranty and Web based information. Information in
instructions for use must also be consistent with any legal requirements which may result from
any warranty stipulations. Consistent terminology shall be used in the instructions for use, on
the product and its packaging, and in supplementary materials, all training and promotional
materials including markings, labels and transport packaging.
4.1.4 Product warranty
The product warranty shall include all relevant terms and conditions (for example, date of
expiry, service conditions, allowed modifications, availability of spare parts), and shall be
provided together with the instructions for use.
It may be appropriate to put the product warranty into a separate document especially when
the terms vary between different sales channels or countries.
4.1.5 Information provided after sale of products
After the product has passed into the user’s possession, it can be helpful to provide, via
Internet based message exchange or other means of communication to
