16、rotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. T
17、o this end and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmenta
18、l organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC
19、 on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested National Committees. 3) The documents produced have the form of recommendations for international use and are pub
20、lished in the form of standards, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their
21、national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be
22、 in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committ
23、ees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a technical report of one of the following types: type 1, when the required support cannot be obtained for the publication of an International Standard, despite repeated effo
24、rts; type 2, when the subject is still under technical development or where for any other reason there is the future but no immediate possibility of an agreement on an International Standard; type 3, when a technical committee has collected data of a different kind from that which is normally publis
25、hed as an International Standard, for example “state of the art”. Technical reports of types 1 and 2 are subject to review within three years of publication to decide whether they can be transformed into International Standards. Technical reports of type 3 do not necessarily have to be reviewed unti
26、l the data they provide are considered to be no longer valid or useful. IEC 1000-5-1, which is a technical report of type 3, has been prepared by subcommittee 77B: High-frequency phenomena, of IEC technical committee 77: Electromagnetic compatibility. The text of this technical report is based on th
27、e following documents: Full information on the voting for the approval of this technical report can be found in the report on voting indicated in the above table. This document is issued in the type 3 technical report series of publications (according to G.3.2.3 of part 1 of the IEC/ISO Directives)
28、as a purely informative document. This document is not to be regarded as an International Standard.

30、terminology Part 2: Environment Description of the environment Classification of the environment Compatibility levels Part 3: Limits Emission limits Immunity limits (in so far as they do not fall under the responsibility of the product committees) Part 4: Testing and measurement techniques Measureme
31、nt techniques Testing techniques Part 5: Installation and mitigation guidelines Installation guidelines Mitigation methods and devices Part 6: Generic standards Part 9: Miscellaneous Each part is further subdivided into sections which are to be published either as International Standards or as techn
32、ical reports. These sections of IEC 1000-5 will be published in chronological order and numbered accordingly. 1 Scope This technical report covers general considerations and guidelines on mitigation methods aimed at ensuring electromagnetic compatibility (EMC) among electrical and electronic apparat
33、us or systems used in industrial, commercial, and residential installations. This technical report is intended for use by installers and users, and to some extent manufacturers, of sensitive electrical or electronic installations and systems, and equipment with high emission levels that could degrad
34、e the overall electromagnetic (EM) environment. It applies primarily to new installations, but where economically feasible, it may be applied to extensions or modifications to existing facilities. Specific topics, such as recommendations on the design and implementation of the earthing system, inclu
35、ding the earth electrode and the earth network, the design and implementation of bonding apparatus or systems to earth or to the earth network, the selection and installation of appropriate cables, and the design and implementation mitigation means involving shielded enclosures, high-frequency filte
36、rs, isolating transformers, surge-protective devices, etc. will be addressed in other sections of part 5. The recommendations presented in this report address the EMC concerns of the installation, not the safety aspects of the installation nor the efficient transportation of power within the install
37、ation. Nevertheless, these two prime objectives are taken into consideration in the recommendations concerning EMC. These two primary objectives can be implemented concurrently for enhanced EMC of the installed sensitive apparatus or systems without conflict by applying the recommended practices pre
38、sented in this report and the relevant safety requirements such as those of IEC 364. As each installation is unique, it is the responsibility of the designer and the installer to select the relevant recommendations most appropriate to a particular installation.
