13、dwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other a
14、ctivities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subj
15、ect dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions det
16、ermined by agreement between the two organizations. 2) The formal decisions or agreements of IEC 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 IEC National Comm
17、ittees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in whic
18、h they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publicat
19、ion and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure tha
20、t they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nat
21、ure whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the reference
22、d publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. Internatio
23、nal Standard IEC 60196 has been prepared by IEC technical committee 8: System aspects for electrical energy supply. The text of this standard is based on the following documents: FDIS Report on voting 8/1262/FDIS 8/1266/RVD Full information on the voting for the approval of this standard can be foun
24、d in the report on voting indicated in the above table. This second edition cancels and replaces the first edition published in 1965. It constitutes a technical revision. The main change is the removal of the standard frequencies for the rayon industry. It has the status of a horizontal standard in
25、accordance with IEC Guide 108. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. BS EN 60196:200960196 IEC:2009 3 The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site u
26、nder “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. BS EN 60196:2009 4 60196 IEC:2009 IEC STANDARD FREQUENCIES 1 Scope The standard frequencies are the frequencies to be
27、 adopted for single-phase and three-phase a.c. systems, for installations in ships, for a.c. traction systems, for tools and for aircraft. This standardization is limited to frequencies up to 10 000 Hz. 2 Terms and definitions For the purposes of this document, the following terms and definitions ap

NOTE 3 The present recommendation is not applicable to the circuits of control devices of machine tools when these circuits form part only of a closed assembly peculiar to one machine tool or to
