FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62391-2 has been prepared by IEC technical committee 40: Capacitors and resistors for electronic equipment.

62391-2  IEC:2006(E) – 9 – 2.2.5 Internal resistance The internal resistance shall be as agreed between the sending and receiving parties.
The internal resistance shall be measured with the d.c. resistance method. However, if a coefficient can be obtained from both d.c. and a.c. resistance methods, the a.c. resistance method may be used for measurement. 3 Quality assessment procedures 3.1 Primary stage of manufacture The primary stage of manufacture is the inspection process for activated carbon electrodes, provided that the activated carbon electrodes include the condition where the collector has been bonded in advance. 3.2 Structurally similar components Capacitors considered as being structurally similar are capacitors produced with similar processes and materials, though they may be of different case sizes and values. 3.3 Declaration of conformity (basic requirements) 3.4 Test schedule and requirement for initial assessment (mandatory and optional tests) The procedures for qualification approval testing are given in IEC 60384-1, 3.5. The schedule to be used for qualification approval testing on the basis of lot-by-lot and periodic tests is given in 3.5 of this specification. The procedure using a fixed sample size schedule is given in 3.4.1 and 3.4.2. 3.4.1 Qualification approval on the basis of the fixed sample size procedures
The fixed sample size procedure is described in IEC 60384-1, 3.5.3b). The sample shall be representative of the range of capacitors for which approval is sought. This may or may not be the complete range covered by the detail specification. For each temperature characteristic, the sample shall consist of specimens of capacitors of maximum and minimum size and, for each of these sizes, the maximum capacitance value for the highest rated voltage and the minimum rated voltage of the voltage ranges for which approval is sought. When there are more than four rated voltages, an intermediate voltage shall also be tested.
The numbers given in Group 0 assume that all groups are applicable. If this is not so, the numbers may be reduced accordingly.
When additional groups are introduced into the qualification approval test schedule, the number of specimens required for Group 0 shall be increased by the same number as that required for the additional groups. Table 1 gives the number of samples to be tested in each group or subgroup together with the number of permissible non-conformances for the qualification approval test.



– 10 – 62391-2  IEC:2006(E) 3.4.2 Tests The complete series of tests specified in Tables 1 and 2 is required for the approval of capacitors covered by one detail specification. The tests of each group shall be carried out in the order given. The whole sample shall be subjected to the tests of Group 0 and then divided for the other groups. Non-conforming specimens (Table 1) found during the tests of Group 0 shall not be used for the other groups. “One non-conforming item” is counted when a capacitor has not satisfied the whole or a part of the tests of a group.
Approval is granted when the number of nonconforming items does not exceed the specified number of permissible non-conforming items for each group or subgroup and the total number of permissible non-conforming items. NOTE Tables 1 and 2 together form the fixed sample size test schedule. Table 1 includes the details for the
sampling and permissible non-conforming items for the different tests or groups of tests. Table 2, together with the details of the test contained in Clause 4, gives a complete summary of test conditions and performance requirements and indicates where, for example for the test method or conditions of test, a choice has to be made in the detail specification. The conditions of test and performance requirements for the fixed sample size test schedule should be identical to those prescribed in the detail specification for quality conformance inspection.
