70 FOREWORD
71 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
72 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
73 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
74 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
75 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
76 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
77 in the subject dealt with may participate in this preparatory work. International, governmental and non -
78 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
79 with the International Organization for Standardization (ISO) in accordance with conditions determined by
80 agreement between the two organizations.
81 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
82 consensus of opinion on the relevant subjects since each technical committee has representation from all
83 interested IEC National Committees.
84 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
85 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
86 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
87 misinterpretation by any end user.
88 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
89 transparently to the maximum extent possible in their national and regional publications. Any divergence
90 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
91 the latter.
92 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
93 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
94 services carried out by independent certification bodies.
95 6) All users should ensure that they have the latest edition of this publication.
96 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
97 members of its technical committees and IEC National Committees for any personal injury, property damage or
98 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
99 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
100 Publications.
101 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
102 indispensable for the correct application of this publication.
103 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
104 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
105 IEC 62391-2 has been prepared by IEC technical committee 40: Capacitors and resistors for
106 electronic equipment. It is an International Standard.
107 This second edition cancels and replaces the first edition published in 2006. This edition
108 constitutes a technical revision.
IEC CDV 62391-2 © IEC 2024 – 5 – 40/3122/CDV
109 This edition includes the following significant technical changes with respect to the previous
110 edition:
111 a) The document has been completely restructured to comply with the ISO/IEC Directives,
112 Part 2; a new technical categorization of test methods has been introduced and the test
113 methods have been reorganized according to these new categories; tables, figures and
114 references have been revised accordingly.
115 b)
116 The text of this International Standard is based on the following documents:
