193 FOREWORD
194 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national
195 electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all
196 questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities,
197 IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS)
198 and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC
199 National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental
200 and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with
201 the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between
202 the two organizations.
203 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus
204 of opinion on the relevant subjects since each technical committee has representation from all interested IEC National
205 Committees.
206 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in
207 that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC
208 cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.
209 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to
210 the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and
211 the corresponding national or regional publication shall be clearly indicated in the latter.
212 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment
213 services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by
214 independent certification bodies.
215 6) All users should ensure that they have the latest edition of this publication.
216 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of
217 its technical committees and IEC National Committees for any personal injury, property damage or other damage of any
218 nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication,
219 use of, or reliance upon, this IEC Publication or any other IEC Publications.
220 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable
221 for the correct application of this publication.
222 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights.
223 IEC shall not be held responsible for identifying any or all such patent rights.
224 IEC 60384-22 has been prepared by IEC technical committee 40: Capacitors and resistors for electronic
225 equipment. It is an International Standard.
226 This fourth edition cancels and replaces the third edition published in 2019, This edition constitutes a
227 technical revision.
228 This edition includes the following significant technical changes with respect to the previous edition:
229 a) . The document has been completely restructured to comply with the ISO/IEC Directives, Part 2 and
230 to make it more useable; tables, figures and references have been revised accordingly.
231 b) The requirements of reference temperature 25°C has been added in Table 5, Table 9, Table 10,
232 Table 12, Table 14 and Table 17.
233 c) The table of temperature characteristics of capacitance for the reference temperature 25°C have
234 been added in Table C.1, Table C.2 and Table C.3.
