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.
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.
International Standard ISO 14982 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for
agriculture and forestry, Subcommittee SC 2, Common tests.

Introduction
In the past years more and more electronic devices designed to control, supervise and indicate multiple functions
have been used in agricultural machines and tractors. The electrical and electromagnetic environment in which
these devices work needs to be taken into consideration.
Electrical and high frequency disturbances emerge during the normal operation of many parts of the machine
devices. They are generated within a large frequency range with different electrical characteristics and, by
conduction and/or radiation, can be imparted to other electronic devices and systems of the machine.
Narrowband signals generated by sources of interference inside or outside the agricultural machines and tractors
can also be coupled in electrical and electronic systems where they can influence the normal function of electrical
devices. Sources of narrowband electromagnetic disturbances are, for example, machines with integrated micro-
processors.
The elaboration of this International Standard is based upon the Commission Directive 95/54/EC (31 October 1995)
"Commission Directive 95/54/EC of 31 October 1995 adapting to technical progress Council Directive 72/245/EEC
on the approximation of the laws of the Member States, relating to the suppression of radio interference produced
by spark-ignition engines fitted to motor vehicles and amending Directive 70/156/EEC on the approximation of the
laws of the Member States relating to the type approval of motor vehicles and their trailers". This procedure was
chosen due to the large conformity of the disturbance phenomena in many domains (motor vehicles, tractors, self-
propelled machinery), similar operation and ambient conditions and the possibility of using the same measuring rig
and measuring apparatus. As far as possible, the measuring procedures described in Directive 95/54/EC have been
replaced by equivalent internationally standardized measuring procedures. However, it was not possible to refer to
International Standards for radiated broadband and narrowband electromagnetic disturbances from machines and
for radiated broadband and narrowband electromagnetic disturbances of electrical/electronic sub-assemblies (ESA).
Therefore the necessary procedures are described in detail in annexes B, C, D and E. International standardization
of the measuring procedures for all types of machines would be desirable for the future.
The electrostatic discharge and the conducted transients are considered to be relevant for agricultural machines
and tractors and therefore (in contrast with the Directive 95/54/EC) are included in this International Standard.
Electrostatic discharges are relevant because also control elements can be positioned outside the cabin and
potential differences can emerge at contact. Conducted transients have to be taken into account because
agricultural machines often represent open systems and several machines are combined with one another. Up to
now, however, only conducted transients along supply lines in 12 V- and 24 V-onboard systems have been dealt
with. The manufacturer is therefore responsible for ensuring that the equipment may withstand conducted transients
which may occur at the switching under load and interactions between systems. Internal cabling and networks
should comply with the state of the art. Conducted transients at signal lines have not yet been treated.
This International Standard has been established as a means of achieving conformity with the requirements of the
EMC Directive (89/336/EEC) and the EMC requirements of the Machine Directive (89/392/EEC).

INTERNATIONAL STANDARD  ISO ISO 14982:1998(E)
Agricultural and forestry machinery — Electromagnetic
compatibility — Test methods and acceptance criteria
1 Scope
This International Standard 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 International Standard.
Electrical/electronic components or sub-assemblies intended for fitting in machines are also within the scope of this
standard, except regarding immunity for those parts whose functions are not involved in the direct control and
modification of the state of the functions of the machine.
This International Standard is not applicable to machines directly supplied with low voltage current from public
electrical mains. Exceptions to machines or electrical/electronic systems or ESA's that may not require testing in
accordance with this International Standard are given in clause 7.
2 Normative references

International Standard. At the time of publication, the editions indicated were valid. All standards are subject to
