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.
ISO 11525-1 was prepared by Technical Committee ISO/TC 110, Industrial trucks, Subcommittee SC 4, Rough-
terrain trucks.
ISO 11525 consists of the following parts, under the general title Rough-terrain trucks — User requirements:
— Part 1: General requirements
Slewing trucks and lorry-mounted trucks are to form the subjects of future parts 2 and 3.

Specific user requirements for rotating trucks, lorry-mounted trucks, personnel work platforms that can be fitted
to rough-terrain trucks, the handling of suspended loads with rough-terrain trucks and agricultural applications
are to be covered by the other parts of ISO 11525.
NOTE National or local requirements can apply, which could be more stringent.

4 General safety requirements
4.1 Principles
This part of ISO 11525 shall be supplemented by good management practices, safety controls and application of
sound principles of safety, training, inspection, maintenance, application selection and operation. All data available
regarding the parameters of intended use and expected environment shall be considered. Those with direct
control over the application and operation of the truck shall be responsible for ensuring good safety practices.
NOTE Different operating conditions can require additional safety precautions, training and special safe
operating procedures.
The operation of any truck is subject to certain hazards that can be protected against only by the exercise of
care and common sense. It is essential to have competent persons trained in the intended use, safe operation,
maintenance and service of this equipment.
