FIXED CAPACITORS FOR USE IN ELECTRONIC EQUIPMENT –
Part 1-1: Generic blank detail specification
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) 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.

IEC 60384-1-1 has been prepared by technical committee 40: Capacitors and resistors for

electronic equipment. It is an International Standard.
The text of this International Standard is based on the following documents:
Draft Report on voting
40/2951/FDIS 40/2964/RVD

INTRODUCTION

This introduction is not intended to be copied into the drafted detail specification. Therefore, it

is positioned in front of the conventional document structure and clause numbering range. It

nevertheless contains normative requirements to the drafted detail specification.

Scope of this generic blank detail specification

This part of IEC 60384-1 is applicable to the drafting of detail specifications for fixed capacitors

for use in electronic equipment.
Function of this generic blank detail specification

This generic blank detail specification is a supplementary document to the sectional

specifications and contains requirements for style, layout and minimum contents of detail

specifications. Detail specifications not complying with these requirements shall not be

considered as being in accordance with IEC specifications nor shall they be described as such.

The detail specification should contain a table of contents prior to the first page of the actual

specification.

In the preparation of the detail specification, the relevant content of the related sectional

specification IEC 60384-X shall be taken into account.

Units, graphical symbols and letter symbols should be chosen, wherever possible, from the

various parts of the IEC 60027 series, the ISO 80000 series and ISO/IEC Guide 99.

This blank detail specification uses for its purpose two different kinds of notes:

For notes which give additional information intended to assist the understanding or use of the

resulting document and therefore shall be copied as NOTE into the drafted detail specification.

As outlined in the ISO/IEC directives, these notes shall not contain any requirement, instruction,

recommendation or permission.

For instructions to the specification writer, COMMENTS are used instead of NOTES. For a clear

distinction, these comments are formatted as IEC-Instructions, as shown in the example below:

COMMENTS For editorial notes which are intended to aid and direct the specification writer and

therefore shall not be copied into the drafted detail specification. In order to accomplish their

function, editorial notes require the use of instructions, recommendations and permissions

addressed to the writer of the detail specification.
Identification of the detail specification and the capacitor

The first page of the detail specification should have a layout starting with a title block as

recommended on the following page.

The numbers in square brackets are editorial references, which are not intended to be copied

into the drafted detail specification, and which correspond to the following information on the

contents which shall be inserted in the indicated positions.

[1] "International Electrotechnical Commission" or the name of the standardization organization

under whose authority the detail specification is published and, if applicable, the

organization from whom the detail specification is available.
---------------------- Page: 8 ----------------------

[2] The number allocated to the detail specification by the IEC or by the responsible

standardisation organisation, together with the date of issue and issue number, as

applicable. Further reference details required by the responsible standardisation

organisation or quality assessment system may be given here, including an established

mark of conformity, as applicable.

[3] The number and issue date and number, as applicable, of the relevant generic specification,

sectional specification and blank detail specification, where the referenced issues shall be

the most recent issues of the respective specifications.

[4] The title of the detail specification, providing a short description of the type of capacitors.

This entry should support the discrimination between similar specifications and should be

suitable for an entry in a register of approvals or in a catalogue of standards. It may duplicate

information given in the textual scope in Clause 1.

[5] An outline drawing or illustration of the products. This entry should aid the easy recognition

of the capacitors and, if possible, support the discrimination between similar specifications.

It may duplicate information given in Figure 1.

[6] Information on the typical construction of the capacitors (where applicable). This entry may

duplicate information given in the textual scope in Clause 1.

[7] The classification level of the capacitors covered by this detail specification, the level of

quality assessment (Assessment level EZ). This information may duplicate information given

in the textual scope in Clause 1.
[8] Optional field for table notes.

[9] Statement(s) about the availability of information on components qualified to this detail

specification, if applied within a full quality assessment system.
