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

This document deals with all significant hazards, hazardous situations and events relevant to
the machine when used as intended or under conditions of misuse reasonably foreseeable by the
manufacturer.
This document is not applicable to the following:
a) machines designed primarily for earth moving, such as loaders or dumpers (see applicable parts of
the ISO 20474 series);
b) truck mixers.
This document does not address hazards that can occur:
— during manufacture;
— when using machines on public roads, where specific local road regulations can apply;
— when operating in potentially explosive atmospheres.
This document is not applicable to machines manufactured before the date of its publication.
