IEC 60938-2-1:2023

Fixed inductors for electromagnetic interference suppression - Part 2-1: Blank detail specification - Inductors for which safety tests are required

IEC 60938-2-1:2023 is applicable to the drafting of detail specifications for fixed inductors for which safety tests are required for use in electronic equipment.
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 shall not be considered as being in accordance with IEC specifications nor shall they so be described.
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 Blank detail specification (BDS);
b) test schedule for quality conformance inspection is moved to an informative annex (Annex B).

Inductances fixes d'antiparasitage - Partie 2-1: Spécification particulière-cadre - Inductances exigeant des essais de sécurité

L’IEC 60938-2-1:2023 s’applique à la rédaction des spécifications particulières pour les inductances fixes qui exigent des essais de sécurité en vue d’une utilisation dans des équipements électroniques.
Une spécification particulière-cadre est un document annexe à la spécification intermédiaire, qui contient des exigences pour le modèle, la disposition et le contenu minimal des spécifications particulières. Les spécifications particulières qui ne satisfont pas à ces exigences ne doivent pas être considérées comme conformes aux spécifications de l’IEC et ne doivent pas être décrites comme telles.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) elle combine l’IEC 60938-2-1:1999 et l’IEC 60938-2-2:1999 en une seule Spécification particulière-cadre (SPC);
b) le programme d’essai pour le contrôle de conformité de la qualité est déplacé vers une annexe informative (Annexe B).

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.
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 Blank detail specification
(BDS);
b) test schedule for quality conformance inspection is moved to an informative annex
(Annex B).
