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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture

This first edition of ISO 14982-2, together with ISO/FDIS 14982-1:— , cancels and replaces ISO 14982:1998,
which has been technically revised.
The main changes are as follows:
— the provisions have been brought up to date with technological change;
— normative references have been updated to the latest editions.
A list of all parts in the ISO 14982 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
This document is a type-C standard as stated in ISO 12100:2010.
This document is of relevance for the following stakeholder groups representing the market players with
regard to machinery safety:
— machine manufacturers;
— health and safety bodies (regulators, accident prevention organizations, 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;
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance;
— 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 or hazardous events are
covered are indicated in the Scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or type-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.

Part 2:
Additional EMC requirements for functional safety
1 Scope
This document specifies test methods and acceptance criteria for evaluating the electromagnetic
compatibility of tractors, and all kinds of mobile (including hand-held) agricultural machinery, forestry
machinery, landscaping, and gardening machinery [referred to hereafter as machine(s)] as supplied by the
machine manufacturer. It is applicable to machines and electrical/electronic sub-assemblies (ESA's) which
are manufactured after the date of publication of this document.
It specifies additional EMC requirements under aspect of functional safety for machinery, ESA and separate ESAs.
This document is only relevant for functions of machine control system failures which when risk assessed to
the relevant ISO 25119 part (or the equivalent when other electronic functional safety standards are used),
are greater than or equal to AgPLr b (or the equivalent).
Electrical and electronic components or separate ESAs intended to be used in the applicable machinery
control functions are also dealt with by this document.
The following electromagnetic disturbance phenomena are evaluated:
— radiated electromagnetic field by off-board sources with various field strength and frequency;
— radiated electromagnetic field by portable transmitters (antenna inside/outside) with various field
strength and frequency;
— electrical field (wire conducted electrical fields);
— electrostatic discharge.
Annex A provides additional information regarding the effects of life cycle and ageing on EMC performance.
Annex B provides additional information for performing the portable transmitter test.
This document is not applicable to machines directly supplied with low v
