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

3 Quality assessment procedures
3.1 Primary stage of manufacture
The primary stage of manufacture is the forming of the tantalum oxide dielectric.
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 Certified records of released lots
The information required in 3.9 of IEC 60384-1 shall be made available when prescribed in
the detail specification and when requested by a purchaser. After the endurance test, the
parameters for which variables information is required are the capacitance change, tan δ and
the leakage current.
3.4 Qualification approval
The procedures for qualification approval testing are given in 3.5 of IEC 60384-1.
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 Sampling
The fixed sample size procedure is described in 3.5.3b) of IEC 60384-1. 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. The sample shall consist of specimens
having the lowest and highest voltages and, for these voltages, the smallest and largest case
size. When there are more than four case sizes an intermediate case size shall also be
tested. In each of these case size/voltage combinations (values), the highest capacitance
shall be chosen. Thus, for the approval of a range, testing is required of either four or six
values. When the range consists of less than four values, the number of specimens to be
tested shall be that required for four values.
Spare specimens are permitted as follows:
Two (for six values) or three (for four values) per value, which may be used as replacements
for specimens which are non-conforming because of incidents not attributable to the
manufacturer.
The numbers given in Group 0 assume that all groups are applicable. If this is not so, the
numbers may be reduced accordingly.

– 12 – 60384-3 © IEC:2006
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 A.1 gives the number of samples to be tested in each group or subgroup together with
the permissible number of non-conforming items for qualification approval tests.
3.4.2 Tests
The complete series of tests for selected assessment level given in Tables A.1 to A.3 and the
test schedule given in Annex B are 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 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 non-conforming 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 1 Tables A.1 and B.1 together form the fixed sample size test schedule. Annex A includes the details for
sampling and the permissible non-conforming items for the different tests or groups of tests, whereas Annex B,
together with the details of tests contained in Clause 4, gives a complete summary of test conditions and
performance requirements indicating where, for example for the test method or conditions of test, a choice should
be made in the detail specification.
NOTE 2 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.
3.5 Quality conformance inspection
3.5.1 Formation of inspection lots
3.5.1.1 Groups A and B inspection
These tests shall be carried out on a lot-by-lot basis according to test plan for selected
assessment level in Table A.2.
A manufacturer may aggregate the current production into inspection lots subject to the
following safeguards:
1) the inspection lot shall consist of structurally similar capacitors (see 3.2);
2a) the sample tested shall be representative of the values and dimensions contained in the
inspection lot:
– in relation to their number;
– with a minimum of five of any one value;
2b) if there are less than five of any one value in the sample, the basis for the drawing of
samples shall be agreed between the manufacturer and the National Supervising
Inspectorate.
60384-3 © IEC:2006 – 13 –
3.5.1.2 Group C inspection
These tests shall be carried out on a periodic basis according to the test plan for selected
assessment level given in Table A.3.
Samples shall be representative of the current production of the specified periods and shall
be divided into small, medium and high sizes. In order to cover the range of approvals in any
period, one voltage shall be tested from each group of sizes. In subsequent periods other
sizes and/or voltage ratings in production shall be tested with the aim of covering the whole
range of approval.
3.5.2 Test schedule
The test schedule for qualification approval is given in Annex B.
3.5.3 Delayed delivery
When, according to the procedures of 3.10 of IEC 60384-1, re-inspection has to be made,
solderability, capacitance and leakage current shall be checked as specified in Group A and B
inspection.
3.5.4 Assessment levels
The assessment level(s) given in the blank detail specification shall preferably be selected
from Tables A.2 to A.3.
