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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).

Introduction
General
This document is a type-C standard as stated in ISO 12100.
The machines concerned and the extent to which hazards, hazardous situations or hazardous events
are covered are indicated in the Scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or B
standards, the requirements of this type-C standard take precedence over the requirements of the
other standards for machines that have been designed and built according to the requirements of this
type-C standard.
The ISO 3691- series of standards covers safety requirements and their verification for industrial trucks
as defined in ISO 5053-1.
Structure
An important step forward in the work on the ISO 3691- series of standards was the agreement to issue
a new structure of International Standards for industrial trucks having on one side basic standards for
all kinds of trucks (see Foreword) and on the other side independent standards to cover the respective
specific functions of industrial trucks, e.g. visibility, noise, vibration, electrical requirements, etc.
Assessment of hazards
The product needs to be designed in such a way that it is fit for its purpose or function and can be
adjusted and maintained without putting persons at risk when used under the conditions foreseen by
the manufacturer.
In order to properly design a product and to cover all specific safety requirements, the manufacturer
will have to identify the hazards that apply to his product and carry out a risk assessment. The
manufacturer will then need to design and construct the product taking this assessment into account.
The aim of this procedure is to eliminate the risk of accidents throughout the foreseeable lifetime of
the machinery, including the phases of assembling and dismantling where risks of accidents could also
arise from foreseeable abnormal situations.
In selecting the most appropriate methods, the manufacturer will need to apply the following principles,
in the order given here:
a) eliminate or reduce risks as far as possible by design (inherently safe machinery design and
construction);
b) take the necessary protective measures in relation to risks that cannot be eliminated by design;
c) inform users of any shortcoming of the protective measures adopted;
d) indicate whether any particular training is required;
e) specify any need to provide personal protection equipment;
f) refer to the appropriate user’s document for proper operating instructions.
Industrial trucks need to be designed to prevent foreseeable misuse wherever possible, if such would
engender risk. In other cases, the instructions will need to draw the user’s attention to ways shown by
experience in which the machinery ought not to be used.
This part of ISO 3691 does not repeat all the technical rules which are state-of-the art and which are
applicable to the material used to construct the industrial truck. Reference will also need to be made
to ISO 12100.

ISO 3691-2:2016(E)
Legislative situation/Vienna Agreement
From the very beginning, the task of the working group was to revise ISO 3691:1980 and establish
worldwide basic standards to comply with the major legislative regulations in, for example, the EU,
Japan, Australia and North America.
Every effort was made to develop a globally relevant International Standard. That goal was achieved
with most of the issues. For several potential problem areas compromises were needed and will
be needed in the future. Where divergent regional requirements remain, these are addressed by
ISO/TS 3691-7 and ISO/TS 3691-8.
In order to ensure that the revised International Standard will be actively used in the ISO member
countries, worldwide, procedures will be necessary to replace the existing national standards and
technical regulations by the revised International Standard. In the European Community, ISO and the
European Committee for Standardization (CEN) agreed on technical co-operation under the Vienna
Agreement, with the aim of replacing European Standards (EN) by International Standards. Other
countries are asked to make similar agreements to ensure that their national standards and technical
regulations are replaced by this International Standard.
Only by these actions will there be the guarantee that products in accordance with International
Standards can be shipped worldwide freely without any technical barriers.
INTERNATIONAL STANDARD ISO 3691-2:2016(E)
Industrial trucks — Safety requirements and
verification —
Part 2:
Self-propelled variable-reach trucks
1 Scope
This part of ISO 3691 gives safety requirements and the means for their verification for self-propelled
industrial variable-reach trucks and variable-reach container handlers/reach stackers as defined in
ISO 5053-1 (hereafter referred to as trucks), equipped with forks or integral load-handling devices for
normal industrial duties (e.g. fork arms or means, such as spreaders, for handling containers).
It is not applicable to
— rough-terrain variable-reach trucks,
— rough-terrain variable-reach trucks for handling containers,
— machines designed primarily for earth-moving (e.g. loaders and dozers), even when their buckets
and blades are replaced with forks,
— machines from which the load can swing freely in all directions.
For the purposes of this part of ISO 3691, fork arms and integrated attachments are considered to be
a part of the truck, whereas attachments/equipment mounted on the load carrier or on the fork arms
which are removable by the user are not. Nevertheless, requirements for such attachments are also
given by the document.
Any regional requirements additional to the provisions of this part of ISO 3691 are addressed in
ISO/TS 3691-7 and ISO/TS 3691-8.
This part of ISO 3691 deals with all significant hazards, hazardous situations or hazardous events, as
listed in Annex B, with the exception of the following, relevant to the applicable machines when used as
intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.
It does not establish requirements for hazards that can occur
— during construction,
— when using trucks on public roads,
— when operating in potentially explosive atmospheres, or
— when lifting persons.
