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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
This redline version of the official IEC Standard allows the user to identify the changes made
to the previous edition IEC 60384-14-1:2016. A vertical bar appears in the margin wherever a
change has been made. Additions are in green text, deletions are in strikethrough red text.

IEC 60384-14-1 has been prepared by IEC technical committee 40: Capacitors and resistors
for electronic equipment. It is an International Standard.
This fourth edition cancels and replaces the third edition published in 2016. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) the tables for dimensions have been replaced with a guidance text in the document;
b) the possibility to give the requirements for the service in DC applications and in high
humidity conditions have been added;
c) the changes in this document in comparison with the previous edition are given in Annex B.
The text of this International Standard is based on the following documents:

INTRODUCTION
0 Blank detail specification
0.1 General
This blank detail specification forms the basis for a uniform procedure for a common
international safety mark. It implements the approval schedule for safety tests in IEC 60384-14,
requires specifies a declaration of design for parameters relevant to safety and indicates
conformance tests to be conducted on every lot prior to its release and requalification tests
depending on changes to the declared design.
This specification offers the assessment level DZ (zero defects).
The use of IEC 60384-14-1, may be more appropriate for components manufactured in mass
production, whereas the employment of IEC 60384-14-2 (safety tests only) may be necessary
in those cases where approval and requalification tests contribute considerably to the costs of
the product.
A blank detail specification is a supplementary document to the sectional specification and
contains requirements for style, layout and minimum content of detail specifications. Detail
specifications not complying with these requirements may are not be considered as being in
accordance with IEC specifications, nor shall should they so be described.
In the preparation of detail specifications the content of 1.4 of the sectional specification shall
be taken into account, refer to IEC 603984-14:2023, Clause 7.
0.2 Identification of the detail specification
The first page of the detail specification should have the layout recommended on the next page
of this blank detail specification. The numbers between square brackets in the layout
correspond to the following information in [1] to [4] which shall should be inserted at the position
indicated:
[1] The "International Electrotechnical Commission" or the National Standards Organization
under whose authority the detail specification is drafted.
[2] The IEC or National Standards number of the detail specification, date of issue and any
further information required by the national system.
[3] The number and issue number of the IEC, or national, generic, or sectional specification,
as relevant.
[4] If different from the IEC number, the national number of the detail specification, date of
issue and any further information required by the national system, together with any
amendment numbers.
0.3 Identification of the capacitor
The numbers between square brackets in the layout correspond to the following information in
[5] to [9] which should be inserted at the position indicated.
[5] A short description of the type of capacitor or range of capacitors. The text should be
suitable for an entry in the IECQ register of approvals.
[6] Information on typical construction (when applicable). The text should be suitable for an
entry in the IECQ register of approvals.
[7] Outline drawing with main dimensions which are of importance for either interchangeability
and/or reference to the appropriate national or international documents for outlines.
Alternatively, the drawing may can be given in an annex to the detail specification, but [7]
should always contain an illustration of the general outer appearance of the component.
[8] The level(s) of quality assessment covered by the detail specification, as appropriate.
[9] Reference data giving information on the most important properties of the component which
allow comparison between the various component types intended for the same or similar
