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.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions 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
and forestry, Subcommittee SC 19, Agricultural electronics.
This second edition cancels and replaces the first edition (ISO 15003:2006), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— integration of editorial corrections;
— updates to the list of normative references and guidance on the application of the normative
references;
— removal of the dates of the normative references;
— correction in the Bibliography.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Agricultural engineering — Electrical and electronic
equipment — Testing resistance to environmental
conditions
1 Scope
This document provides design requirements and guidance for the manufacturers of electrical and
electronic equipment for use in all kinds of mobile (including hand-held) agricultural machinery,
forestry machinery, landscaping and gardening machinery [referred to hereafter as machine(s)]. The
term machinery covers tractors and implements. This document gives tests for specific environmental
conditions and defines severity levels for tests which relate to the environmental extremes that can be
experienced in practical operation of the equipment.
This document is intended to be used in determining the suitability of the equipment of these machines,
for use in a specified range of environmental conditions.
NOTE The severity levels given are general guidelines and not guaranteed worst-case exposure levels.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at http:// www .electropedia .org/
3.1
display device
device displaying alpha-numeric characters or graphical symbols designed to be read and interacted
with by operative or service personnel to adjust and control operation of equipment (3.2)
3.2
equipment
self-contained electronic system containing electric, electronic and mechanical components which is
electrically connected to other machinery (including power sources) by means of connectors
3.3
impaired function
state in which one or more of the functions of the equipment (3.2) as stated by the manufacturer are not
operative or do not conform to the manufacturer's specification
3.4
location
position within machines where the equipment (3.2) will normally be operating
3.5
normal mounting configuration
orientation of the equipment (3.2) when in normal use
3.6
severity level
severity of the conditions under which an environmental test is undertaken, selected according to the
intended location (3.4) and application of the equipment (3.2)
4 General
4.1 General conditions for testing
Except where otherwise specified for a test, testing shall be carried out under standard reference
conditions as specified in IEC 60068-1:2013, Section 4. The severity levels used shall be recorded in the
test report. Tests shall be conducted in accordance with IEC 60512-1.
It is desirable to use the same sample of equipment in all tests unless specified otherwise for a test.
It is recommended that a functionality check be done before and after each test and that functionality
be monitored during a test when practical.
Combined testing is advisable in cases where equipment is subjected in use to extremes of two or more
different environmental factors simultaneously (e.g. temperature and vibration) and recorded as such
on the test report.
NOTE Combined testing can be used as a means of reducing overall test time.

4.2 Test sequence
The electromagnetic compatibility tests shall be carried out last, since electromagnetic emissions and
susceptibility can be affected by prior exposure to other tests. The test sequence shall be recorded in
the test report.
The tests should be carried out in progressively increasing order of severity.
4.3 Test report
The test report shall, as a minimum, include the following information:
— description of the equipment;
— model number or other identification;
— manufacturer’s name and address;
— test lab’s name and address;
— test date(s);
— tests to be conducted;
— test equipment used/calibration status and test set up information;
— the order in which the tests were conducted;
— duration of each individual test conducted;
— severity level used for testing;
— test results;
— any additional details regarding the test.
An example test report is given in Annex A.
4.4 ISO 16750 conformance
Electrical and electronic equipment in accordance with ISO 16750 requirements that correspond to
the requirements of this document conforms with this document. Annex C provides a summary of
the ISO 16750 parts that contain similar test procedures as specified in this document. It provides a
cross reference to assist in the determination whether an electrical and electronic equipment tested in
accordance with the relevant part of ISO 16750 meets the requirements of this document or requires
additional testing.
5 Tests
5.1 Monitoring for impaired function
Where equipment is to be monitored for impaired function during or after a test, the equipment
