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).

Introduction
This document is a type-B1 standard as stated in ISO 12100:2010.
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.
In addition, this document is intended for standardization bodies elaborating type-C standards.
The requirements of this document can be supplemented or modified by a type-C standard.
For machines which are covered by the scope of a type-C standard and which have been designed and
built according to the requirements of that standard, the requirements of that type-C standard take
precedence.
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.
The purpose of this document is to establish general design principles for partially automated, semi-
2)
autonomous and autonomous (see ISO 18497-1 ) functions of agricultural machinery and tractors.
Manual non-automated functions are addressed in existing agricultural machinery and tractor safety
standards. Due to the potential number of different functions of agricultural machinery and tractors
and the mixed type and mode to which these functions can exist, it is necessary to establish general
design principles. In this way, the combination, operator location, and types of interaction of these
functions can be guided so that further type-C safety standards can be developed consistently and
explicitly to address the mitigation of risk of injury to operators and bystanders. This is the primary
focus of safety standards. Attempting to define risk mitigation requirements based on combinations of

type and mode of functions alone cannot be accomplished accurately for all agricultural machinery and
tractors due to the wide variety of the machinery and variety of functionality.
[1]
Therefore, the familiar representation of SAE J3016 with six levels of automation was deliberately
not chosen as a basis for this document and it is necessary to develop more specific type-C safety
standards, using the general design principles of this document, to adequately account for the risks of
agricultural machinery and tractors used in a specified way with various types of partially automated,
semi-autonomous and autonomous functions.
When the requirements of this document for partially automated, semi-autonomous and autonomous
functions of agricultural machinery and tractors are different from those which are stated in a
machine-specific type-C standard dealing with partially automated, semi-autonomous and autonomous
functions of agricultural machinery and tractors, the requirements of the machine-specific standard
take precedence over the requirements of this document.

DRAFT INTERNATIONAL STANDARD ISO/DIS 18497-3:2022(E)
Agricultural machinery and tractors — Safety of
partially automated, semi-autonomous and autonomous
machinery —
Part 3:
Autonomous operating zones
1 Scope
This document specifies principles for the design of agricultural machinery and tractors utilizing
autonomous operating zones that are used in agricultural applications and that have partially
automated, semi-autonomous and autonomous functions. Additionally, it provides guidance on the type
of information, to be provided by the manufacturer, on safe working practices (including information
about residual risks).
The autonomous operating zone itself is not in scope of this document. It can include, for example,
considerations for the autonomous operating zone location, physical or virtual boundaries, physical
boundary types (natural or man-made) and the associated risks with the autonomous operating zone
design.
The purpose of this document is to assist in the provision of more specific safety requirements, means of
verification and information for use to ensure an appropriate level of safety for agricultural machinery
and tractors with partially automated, semi-autonomous and autonomous functions used in a specified
way.
This document deals with all the significant hazards, hazardous situations and events, relevant to
agricultural machinery and tractors with partially automated, semi-autonomous and autonomous
functions when used as intended and under the conditions of misuse foreseeable by the manufacturer
during normal operation and service.
Applicability of the design principles and any additional detailed requirements, for design, verification,
validation or information for use are outside the scope of this document. When risk assessment
concludes that hazards are not significant hazards, the principles of this document do not apply.
NOTE Safety requirements for specific non-automated functions of agricultural machinery and tractors can
be available in machine-specific type-C standards.
This document is not applicable to:
— forestry applications;
— operations on public roads including relevant requirements for braking and steering systems.
This document is not applicable to agricultural machinery and tractors which are manufactured before
the date of its publication, or to systems applied to agricultural machinery and tractors put into use
before the date of its publication.

4 Safety requirements and protective or risk reduction measures
4.1 General
Agricultural machinery and tractors that have partially automated, semi-autonomous and autonomous
functions (see Figure 1) and which utilize autonomous operating zones as a measure to reduce risks
related to obstacle contact as a significant hazard, as defined in ISO 12100:2010; 3.8, shall be designed
according to the principles of 4.2 for protective or risk reduction measures.
Significant hazards are dependent on use case of agricultural machinery and tractors with partially
automated, semi-autonomous and autonomous functions and shall be determined using a risk
assessment according to ISO 12100:2010.
In addition, agricultural machinery and tractors that have partially automated, semi-autonomous and
autonomous functions and which utilize autonomous operating zones shall be designed according
to the principles of ISO 12100:2010 for relevant but not significant hazards which are not dealt with
by this document. For significant hazards not covered in 4.2, the determination of requirements and
corresponding verification procedures shall be done according to ISO 12100:2010.
Specific type-C standards, when available, can give more detailed requirements.
