Part 2-1: Blank detail specification –
Inductors for which safety tests are required



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 60938-2-1 has been prepared by IEC technical committee 40: CAPACITORS AND
RESISTORS FOR ELECTRONIC EQUIPMENT. It is an International Standard.
This second edition cancels and replaces the first edition published in 1999. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) It combines IEC 60938-2-1:1999 and IEC 60938-2-2:1999 into one BDS.
b) Test schedule for quality conformance inspection is moved to an informative Annex

10 Blank detail specification
11 A blank detail specification is a supplementary document to the sectional specification and
12 contains requirements for style, layout and minimum content of detail specifications. Detail
13 specifications not complying with these requirements shall not be considered as being in
14 accordance with IEC specifications nor shall they so be described.
15 In the preparation of detail specifications, the content of 4.3 of the sectional specification shall
16 be taken into account.
17 The numbers between square brackets on the first page of the detail specification correspond
18 to the following information which shall be inserted in the position indicated.
19 Identification of the detail specification
20 [1] The "International Electrotechnical Commission" or the National Standards Organization
21 under whose authority the detail specification is drafted.
22 [2] The IEC or National Standards number of the detail specification, date of issue and any
23 further information required by the national system.
24 [3] The number and issue number of the IEC or national generic specification.
25 [4] The IEC number of the blank detail specification.
26 Identification of the inductor
27 [5] A short description of the type of inductor.
28 [6] Information on typical construction (when applicable).
29 [7] Outline drawing with main dimensions which are of importance for interchangeability
30 and/or reference to the national or international documents for outlines. Alternatively,
31 this drawing may be given in an annex to the detail specification.
32 [8] Application or group of applications covered and/or assessment level.
33 [9] Reference data on the most important properties, to allow comparison between the
34 various inductor types.
