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
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

as well as information about ISO's adherence to the World Trade Organization (WTO) principles in the
Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html.
ISO 4254-8 was prepared by the European Committee for Standardization (CEN) in collaboration with
ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 3, Safety and comfort,
in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 4254-8:2009), which has been technically
revised and includes the following changes:
— revision of the edition 2009 under the Vienna Agreement (whole document);
— alignment with ISO 4254-1:2003 (whole document);
— addition of terms and definitions (3.5, 3.6);
— improved differentiation concerning the access for loading with and without load (4.5);
— additional requirements concerning the removal of spreading devices (4.8);
— addition of noise reduction requirements (4.10);
— alignment of the list of significant hazards (Annex A).

Introduction
This document is of relevance, in particular, for the following stakeholder groups representing the
market players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organisations, market surveillance etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— 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
standards for machines that have been designed and built according to the provisions of this type-C
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.
INTERNATIONAL STANDARD ISO 4254-8:2018(E)
Agricultural machinery — Safety —
Part 8:
Solid fertilizer distributors
1 Scope
This document, 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 in agriculture and to be used by one operator only,
e.g. 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. In
addition, it specifies the type of information on safe working practices (including residual risks) to be
provided by the manufacturer.
This document 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
foreseeable 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;
— moving parts for power transmission except for strength requirements for guards.
This document is neither applicable to maintenance or repairs carried out by professional service
personnel nor to environmental hazards (except noise).
This document 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 document is not applicable to solid fertilizer distributors which are manufactured before the date
of its publication.
When requirements of this document are different from those which are stated in ISO 4254-1, the
requirements of this document take precedence over the requirements of ISO 4254-1 for machines that
have been designed and built according to the provisions of this document.
