48 LITHIUM ION CAPACITORS FOR USE

50 TEST METHODS FOR ELECTRICAL CHARACTERISTICS
52 FOREWORD
53 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
54 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
55 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
56 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
57 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
58 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
59 in the subject dealt with may participate in this preparatory work. International, governmental and non-
60 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
61 with the International Organization for Standardization (ISO) in accordance with conditions determined by
62 agreement between the two organizations.
63 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
64 consensus of opinion on the relevant subjects since each technical committee has representation from all
65 interested IEC National Committees.
66 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
67 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
68 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
69 misinterpretation by any end user.
70 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
71 transparently to the maximum extent possible in their national and regional publications. Any divergence
72 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
73 the latter.
74 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
75 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
76 services carried out by independent certification bodies.
77 6) All users should ensure that they have the latest edition of this publication.
78 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
79 members of its technical committees and IEC National Committees for any personal injury, property damage or
80 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
81 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
82 Publications.
83 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
84 indispensable for the correct application of this publication.
85 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
86 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
87 IEC 62813 has been prepared by IEC technical committee 40: Capacitors and resistors for
88 electronic equipment. It is an International Standard.
89 This second edition cancels and replaces the first edition published in 2015.
90 This edition includes the following changes with respect to the previous edition:
91 a) The document has been restructured to comply with the ISO/IEC Directives, Part 2.

Draft Report on voting
XX/XX/FDIS XX/XX/RVD
96 Full information on the voting for its approval can be found in the report on voting indicated in
97 the above table.
98 The language used for the development of this International Standard is English.
99 This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
100 accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
101 at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
102 described in greater detail at www.iec.ch/publications.
103 The committee has decided that the contents of this document will remain unchanged until the
104 stability date indicated on the IEC website under webstore.iec.ch in the data related to the
105 specific document. At this date, the document will be
106 • reconfirmed,
107 • withdrawn,
108 • replaced by a revised edition, or
109 • amended.
