— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e. g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered
are indicated in the scope of this document. These hazards are specific to solid 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.
This document is a type-C standard as stated in ISO 12100.
When provisions of this type-C standard are different from those which are stated in type-A or type-B
standards, the provisions of this type-C standard take precedence over the provisions of the other

standard.
The structure of safety standards in the field of machinery is as follows.
— Type-A standards (basis standards) give basic concepts, principles for design, and general aspects
that can be applied to machinery.
— Type-B standards (generic safety standards) deal with one or more safety aspects or one or more
types 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-hands controls, interlocking devices, pressure
sensitive devices, guards).
— Type-C standards (machinery safety standards) deal with detailed safety requirements for a
particular machine or group of machines.

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 4254-8 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and
forestry, Subcommittee SC 3, and by Technical Committee CEN/TC 144, Tractors and machinery for
agriculture and forestry in collaboration.
This second edition cancels and replaces the first edition (2009), 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 mowers and flail mowers
Part 2, Anhydrous ammonia applicators, has been withdrawn, Part 3, Tractors, has been cancelled and
replaced by ISO 26322 (all parts), Tractors for agriculture and forestry — Safey, and Part 4, Forestry winches,
has been cancelled and replaced by ISO 19472, Machinery for forestry — Winches — Dimensions,

Introduction
The structure of safety standards in the field of machinery is as follows.
 Type-A standards (basis standards) give basic concepts, principles for design, and general aspects that
can be applied to machinery.
 Type-B standards (generic safety standards) deal with one or more safety aspects or one or more types
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-hands controls, interlocking devices, pressure sensitive
devices, guards);
 Type-C standards (machinery safety standards) deal with detailed safety requirements for a particular
machine or group of machines.
This part of ISO 4254 is a type-C standard as stated in ISO 12100.
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 solid 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.
When provisions of this type-C standard are different from those which are stated in type-A or type-B
standards, the provisions of this type-C standard take precedence over the provisions of the other standards
for machines that have been designed and built according to the provisions of this type-C standard.

Agricultural machinery — Safety — Part 8: Solid fertilizer
distributors
1 Scope
This part of ISO 4254, intended 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 or self-propelled fertilizer
distributors for solid fertilizer application, i.e. full width solid fertilizer distributors, solid fertilizer broadcasters,
distributors with oscillating tube and line-distributors as well as solid fertilizer distributors driven by an auxiliary
engine to be used by one operator only, used in agriculture. 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 deals with all the significant hazards ( as listed in Annex A), hazardous situations and
events relevant to solid fertilizer distributors, when they are used as intended and under the conditions
foreseen by the manufacturer (see Clause 4), excepting the hazards arising from:
 inadequate lighting of working area;
 inadequate visibility from drivers/operators position;
 inadequate seating;
 travelling functions (drive, braking etc.);
 rolling over;
 equipment for loading fertilizer into the machine;
 an auxiliary engine.
This part of ISO 4254 is not applicable to electromagnetic compatibility (EMC), nor to environmental hazards
(except noise).
This part of ISO 4254 is not applicable to the following:
 combined seed and fertilizer drills which create a soil trench and deposit fertilizer in said trench;
 machines for distributing granulated pesticides;
 pedestrian controlled distributors;
 knapsack distributors.
This part of ISO 4254 is not applicable to solid fertilizer distributors which are manufactured before the date of
its publication.
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 to the provisions of this part of ISO 4254.
