66 FOREWORD
67 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
68 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
69 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
70 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
71 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
72 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
73 in the subject dealt with may participate in this preparatory work. International, governmental and non-
74 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
75 with the International Organization for Standardization (ISO) in accordance with conditions determined by
76 agreement between the two organizations.77 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
78 consensus of opinion on the relevant subjects since each technical committee has representation from all
79 interested IEC National Committees.80 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
81 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
82 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
83 misinterpretation by any end user.84 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
85 transparently to the maximum extent possible in their national and regional publications. Any divergence
86 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
87 the latter.88 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
89 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
90 services carried out by independent certification bodies.91 6) All users should ensure that they have the latest edition of this publication.
92 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
93 members of its technical committees and IEC National Committees for any personal injury, property damage or
94 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
95 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
96 Publications.97 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
98 indispensable for the correct application of this publication.99 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
100 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
101 IEC 63093-10 has been prepared by IEC technical committee 51: Magnetic components,
102 ferrite and magnetic powder materials. It is an International Standard.103 This first edition cancels and replaces the first edition of IEC 61247 published in 1995. This
104 edition constitutes a technical revision.105 This edition includes the following significant technical changes with respect to IEC 61247:
106 a) The calculations of the effective parameter values have been updated according to the
107 IEC 60205.108 b) Add the limits of surface irregularities.
109 The text of this International Standard is based on the following documents:

119 website.120 The committee has decided that the contents of this document will remain unchanged until the
121 stability date indicated on the IEC website under webstore.iec.ch in the data related to the
122 specific document. At this date, the document will be123 • reconfirmed,

133 This part of IEC 63093 specifies the dimensions that are of importance for mechanical
134 interchangeability for a preferred range of PM-cores made of magnetic oxides, the main
135 dimensions for coil formers to be used with these cores and the locations of their pins on a
136 modular printed wiring grid in relation to the base outlines of cores. It also specifies the
137 effective parameter values to be used in calculations and gives guidelines on allowable limits
138 of surface irregularities applicable to the PM-cores.139 The use of derived standards which give a more detailed specification of component parts
140 whilst still permitting compliance with this standard is discussed in Annex A.
