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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
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.
ISO 15003 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and
forestry, Subcommittee SC 19, Agricultural electronics.

INTERNATIONAL STANDARD ISO 15003:2006(E)
Agricultural engineering — Electrical and electronic
equipment — Testing resistance to environmental conditions
1 Scope
This International Standard 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)]. It 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.
The standard is intended to be used in determining the suitability of the equipment of the 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.

4 General
4.1 General conditions for testing
Except where otherwise specified for a particular test, testing shall be carried out under standard reference
conditions as specified in IEC 60068-1:1998, section 5. 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 particular 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.
