9、s (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,
10、 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
11、/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 m
12、ember 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 ma

14、facturers 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
15、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
16、 levels given are general guidelines and not guaranteed worst-case exposure levels. 2 Normative references The following referenced documents are indispensable for the application of this document.

27、n 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 functiona
28、lity 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 re
29、corded 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
30、 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
31、s name and address; test labs 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 additio
