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 4254-6 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and
forestry, Subcommittee SC 6, Equipment for crop protection.
This second edition cancels and replaces the first edition (ISO 4254-6:1995), which has been technically

Introduction
The structure of safety standards in the field of machinery is as follows:
a) type-A standards (basic standards) giving basic concepts, principles for design, and general aspects that
can be applied to machinery;
b) type-B standards (generic safety standards) dealing with one safety aspect or one type of safeguards that
can be used across a wide range of machinery:
⎯ type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature, noise),
⎯ type-B2 standards on safeguards (e.g. two-hand control devices, interlocking devices,
pressure-sensitive devices, guards);
c) type-C standards (machinery safety standards) dealing with detailed safety requirements for a particular
machine or group of machines.
This document is a type-C standard as stated in ISO 12100.
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 machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this part of ISO 4254. These hazards are specific to sprayers and liquid fertilizer
distributors.
Significant hazards that are common to all the agricultural machines (self-propelled, mounted, semi-mounted
and trailed) are dealt with in ISO 4254-1.
