33、 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
34、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
35、 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
36、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
37、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
38、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
39、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
40、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
41、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
42、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
43、bject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60556 has been prepared by IEC technical committee 51: Magnetic components and ferrite materials. This second edition cancels and replaces the first edition, published
44、in 1982, its amendment 1 (1997) and amendment 2 (2004). This edition constitutes a technical revision. This second edition is a consolidation of the first edition and its amendments 1 and 2. It includes editorial improvements as well as improvements to the figures. This standard is to be read in con
45、junction with IEC 60392. This bilingual version (2011-07) replaces the English version. 6 60556 IEC:2006 The text of this standard is based on the following documents: FDIS Report on voting 51/850/FDIS 51/859/RVD Full information on the voting for the approval of this standard can be found in the re
46、port on voting indicated in the above table. The French version of this standard has not been voted upon. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the stability dat
47、e 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, withdrawn, replaced by a revised edition, or amended. 60556 IEC:2006 7 GYROMAGNETIC MATERIALS INTENDED FOR APPLICATION AT MICROWAVE FREQUE
48、NCIES MEASURING METHODS FOR PROPERTIES 1 Scope This International Standard describes methods of measuring the properties used to specify polycrystalline microwave ferrites in accordance with IEC 60392 and for general use in ferrite technology. These measuring methods are intended for the investigati
49、on of materials, generally referred to as ferrites, for application at microwave frequencies. Single crystals and thin films generally fall outside the scope of this standard. NOTE 1 For the purposes of this standard, the words “ferrite” and “microwave” are used in a broad sense: by “ferrites” is meant not only magneto-dielectric chemical component
