FIXED CAPACITORS FOR USE IN ELECTRONIC EQUIPMENT –

Part 16: Sectional specification: Fixed metallized

polypropylene film dielectric d.c. capacitors

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 60384-16 has been prepared by IEC technical committee 40:

Capacitors and resistors for electronic equipment.
This second edition cancels and replaces the first edition published in 1982, amendment 1
(1987) and amendment 2 (1992) and constitutes minor revisions related to tables, figures and
references.
The text of this standard is based on the following documents:
FDIS Report on voting
40/1595/FDIS 40/1628/RVD

3.4 Qualification approval
The procedures for qualification approval testing are given in the generic specification,

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 below.

3.4.1 Qualification approval on the basis of the fixed sample size procedures

3.4.1.1 Sampling
The fixed sample size procedure is described in IEC 60384-1, 3.5.3 b). 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 lowest and highest capacitances. When there are more than four rated voltages
an intermediate voltage shall also be tested. Thus for the approval of a range, testing is
required of either four or six values (capacitance/voltage combinations). 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:
a) One per value which may be used to replace the permitted defective in Group 0.
b) One per value which may be used as replacements for specimens which are defective
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.
When additional groups are introduced into the qualification approval test schedule, the
number specimens required for Group 0 shall be increased by the same number as that
required for the additional groups.
Table 3 gives the number of samples to be tested in each group or subgroup together with the
permissible number of defectives for qualification approval tests.
3.4.1.2 Tests
The complete series of tests specified in Tables 3 and 4 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 divide
