31、 worldwide 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 ot
32、her activities, 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
33、 subject 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 conditio
34、ns determined 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 Nationa
35、l Committees. 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 i
36、n which 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 Pu
37、blication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC
38、is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that 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 t
39、echnical committees and IEC National Committees for any personal injury, property damage or other damage of any nature 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
40、IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced 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 su
41、bject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60939-1 has been prepared by IEC technical committee 40: Capacitors and resistors for electronic equipment. This third edition cancels and replaces the second edition p
42、ublished in 2005. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) table 3 has been updated, specifying how to handle the Neutral by 3-phase filter with Neutral; b) all details about “Quality assessment” h
43、ave been deleted in this edition, because this standard is a safety standard; c) filters shall be subjected to Test Aa of IEC 60068-2-1 for 16 h, using the degree of severity of the lower category temperature as prescribed in the relevant specification; 6 60939-1 IEC:2010 d) since IEC 60068-2-20 doe
44、s no longer make a difference between Method 1A and 1B, but only describes Method 1, references to the method to be used are updated. The text of this standard is based on the following documents: FDIS Report on voting 40/2046/FDIS 40/2061/RVD Full information on the voting for the approval of this
45、standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 60939 series, under the general title Passive filter units for electromagnetic interference suppression, can
46、 be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed,
47、 withdrawn, replaced by a revised edition, or amended. 60939-1 IEC:2010 7 PASSIVE FILTER UNITS FOR ELECTROMAGNETIC INTERFERENCE SUPPRESSION Part 1: Generic specification 1 General 1.1 Scope This generic specification relates to passive filter units for electromagnetic interference sup- pression for
48、use within, or associated with, electronic or electrical equipment and machines. Both single and multi-channel filters within one enclosure are included within the scope of this generic specification. Filters constructed of capacitive elements where the inductance is inherent in the construction of
49、the filter are within the scope of this specification. Similarly, filters constructed of inductive elements where the capacitance is inherent in the construction of the filter are also within the scope of this generic specification. The manufacturer should state whether a given component is to be designed as a capacitor, an inductor or a filter. The filter units within the scope of
