This standard has been developed to support the Machinery Directive (98/37/EC and 2006/42/EC). However,
other directives can apply to the sprayers such as:
 Pressure Equipment Directives for sprayers where the functioning depends on putting pressure on the
spray tank or for sprayers with piping exceeding DN 200 or exceeding the product pressure DN x PS of
2000 for DN between 25 to 200;
 Electromagnetic Compatibility (EMC) Directive for sprayers including electronic functions.
This second edition cancels and replaces the first edition (EN 907:1997), which has been technically revised.
The following major changes were introduced:
 revision of the requirements related to the folding/unfolding of the boom in relation to the height of the
power lines (5.3.2);
 addition of requirements related to the draining (5.4.3);
 addition of requirements related to the clearance zone for hitching operations (5.11);
 addition of a clause for safe maintenance and servicing on pumps and filters (5.12);
 addition of a noise clause (5.13);
 addition of Annexes ZA and ZB;
 deletion of the requirements related to the guarding of moving parts for power transmission dealt with in
EN 15811:— "Agricultural machinery - Guards for moving parts of power transmission - Guard opening
with tool (ISO/TS 28923:2007);
 deletion of the requirements related to the handheld spraying devices;
 deletion of EN 1553:1999 "Agricultural machinery - Agricultural self-propelled, mounted, semi-mounted and trailed
machines - Common safety requirements" and replacement with EN ISO 4254-1:— "Agricultural machinery -
Safety – Part 1: General requirements" (ISO 4254-1:2008).

countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland and the United Kingdom.

ISO 4254-6:2009(E)
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
revised.
ISO 4254 consists of the following parts, under the general title Agricultural machinery — Safety:
⎯ Part 1: General requirements
⎯ Part 5: Power-driven soil-working machines
⎯ Part 6: Sprayers and liquid fertilizer distributors
⎯ Part 7: Combine harvesters, forage harvesters and cotton harvesters
⎯ Part 8: Solid fertilizer distributors
⎯ Part 9: Seed drills
⎯ Part 10: Rotary tedders and rakes
⎯ Part 11: Pick-up balers
⎯ Part 12: Rotary disc and drum mowers and flail mowers

ISO 4254-6:2009(E)
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.

INTERNATIONAL STANDARD ISO 4254-6:2009(E)

Agricultural machinery — Safety —
Part 6:
Sprayers and liquid fertilizer distributors
1 Scope
This part of ISO 4254, to be used together with ISO 4254-1, specifies the safety requirements and their
verification for the design and construction of mounted, semi-mounted, trailed and self-propelled agricultural
sprayers for use with pesticide products and liquid fertilizer application, designed for use by one operator only.
In addition, it specifies the type of information on safe working practices (including residual risks) to be
provided by the manufacturer.
This part of ISO 4254 is not applicable to:
⎯ pedestrian-controlled sprayers;
⎯ knapsack sprayers;
⎯ aerial sprayers;
⎯ handheld spraying devices (e.g. spray guns).
When requirements of this part of ISO 4254 are different from those which are stated in ISO 4254-1, the
requirements of this part of ISO 4254 take precedence over the requirements of ISO 4254-1 for machines that
have been designed and built according the provisions of this part of ISO 4254.
This part of ISO 4254, taken together with ISO 4254-1, deals with all the significant hazards, hazardous
situations and events relevant to sprayers and liquid fertilizer distributors when they are used as intended and
under the conditions foreseen by the manufacturer (see Clause 4), excepting the hazards arising from:
⎯ automatically actuated height adjustment systems;
⎯ electrostatic phenomena;
⎯ electromagnetic compatibility;
⎯ the environment, other than noise;
⎯ inhalation of spraying chemical products due to a lack of effective methods to maintain breathing air
quality inside the cab;
⎯ roll-over and tip-over of self-propelled machines with a ride-on driver;
⎯ vibration (except the declaration);
⎯ dust emission;
⎯ burns;
ISO 4254-6:2009(E)
⎯ moving parts for power transmission except strength requirements for guards and barriers;
⎯ safety and reliability of control systems;
⎯ travelling function of self-propelled machines.
NOTE ISO 14982 specifies test methods and acceptance criteria for evaluating the electromagnetic compatibility of
all kind of mobile agricultural machinery.
This part of ISO 4254 is not applicable to sprayers and liquid fertilizer distributors which are manufactured
before the date of publication of this document by ISO.

4 List of significant hazards
Table 1 gives the significant hazard(s), the significant hazardous situation(s) and hazardous event(s) covered
by this part of ISO 4254 that have been identified by risk assessment as being significant for this type of
machine, and which require specific action by the designer or manufacturer to eliminate or to reduce the risk.
Attention is drawn to the necessity to verify that the safety requirements specified in this part of ISO 4254
apply to each significant hazard presented by a given machine and to validate that the risk assessment is
complete.
