50 FOREWORD
51 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
52 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
53 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
54 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
55 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
56 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt w ith
57 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
58 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
59 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
60 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
61 consensus of opinion on the relevant subjects since each technical committee has representation from all
62 interested IEC National Committees.
63 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
64 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
65 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
66 misinterpretation by any end user.
67 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
68 transparently to the maximum extent possible in their national and regional publications. Any divergence between
69 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in t he latter.
70 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
71 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
72 services carried out by independent certification bodies.
73 6) All users should ensure that they have the latest edition of this publication.
74 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
75 members of its technical committees and IEC National Committees for any personal injury, property damage or
76 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
77 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
78 Publications.
79 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
80 indispensable for the correct application of this publication.
81 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
82 rights. IEC shall not be held responsible for identifying any or all such patent rights.
83 International standard IEC 61558-2-5 has been prepared by IEC technical committee 96:
84 Transformers, reactors, power supply units and combinations thereof.
85 This third edition cancels and replaces the second edition published in 2010. This edition
86 constitutes a technical revision.
87 This edition includes the following significant technical changes with respect to the previous
88 edition:
89 a) adjustment of structure and references in accordance with IEC 61558-1:2017;
90 b) new symbol for power supply unit with linearly regulated output voltage.

104 This document supplements or modifies the corresponding clauses in IEC 61558-1:2017, so as
105 to convert that publication into the IEC standard: Particular requirements and tests for
106 transformers for shavers, power supply units for shavers and shaver supply units.
107 A list of all parts in the IEC 61558 series published under the general title Safety of transformers,
108 reactors, power supply units and combinations thereof, can be found on the IEC website.
109 Future standards in this series will carry the new general title as cited above. Titles of existing
110 standards in this series will be updated at the time of the next edition.
111 Where this document states "addition", "modification" or "replacement", the relevant text of
112 IEC 61558-1:2017 is to be adopted accordingly.
113 In this document, the following print types are used:
114 − requirements proper: in roman type;
115 − test specifications: in italic type;
116 − explanatory matter: in smaller roman type.
117 In the text of this document, the words in bold are defined in Clause 3.
118 Subclauses, notes, figures and tables additional to those in IEC 61558-1:2017 are numbered
119 starting from 101; supplementary annexes are entitled AA, BB, etc.
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 www.webstore.iec.ch in the data related to the
122 specific document. At this date, the document will be
