Miniature fuses - Part 2: Cartridge fuse-links
IEC 60127-2:2014 relates to special requirements applicable to cartridge fuse-links for miniature fuses with dimensions measuring 5 mm x 20 mm and 6,3 mm x 32 mm for the protection of electric appliances, electronic equipment and component parts thereof, normally intended for use indoors. It does not apply to cartridge fuse-links for appliances intended to be used under special conditions, such as in corrosive or explosive atmospheres. This standard applies in addition to the requirements of IEC 60127-1. The object of this standard is to define special and additional test methods for cartridge fuse-links applying in addition to the requirements of IEC 60127-1. This third edition of IEC 60127-2 cancels and replaces the second edition published in 2010. This edition includes the following significant technical changes with respect to the previous edition: add 4 new standard sheets 7 up to 10. Keywords: cartridge fuse-links for miniature fuses, protection of electric appliances, electronic equipment and component
This publication is to be read in conjunction with IEC 60127-1:2006.
Coupe-circuit miniatures - Partie 2: Cartouches
L'IEC 60127-2:2014 se rapporte à des exigences particulières applicables aux éléments de remplacement à cartouche pour coupe-circuit miniatures de dimensions de 5 mm x 20 mm et de 6,3 mm x 32 mm pour la protection d'appareils électriques, de matériels électroniques et de leurs composants, destinés normalement à être utilisés à l'intérieur de bâtiments. Elle n'est pas applicable aux éléments de remplacement à cartouche pour les appareils destinés à être utilisés dans des conditions particulières, telles que les atmosphères corrosives ou explosives. La présente norme s'applique en plus des exigences de l'IEC 60127-1. La présente norme a pour objet de définir des méthodes d'essai particulières et supplémentaires applicables aux éléments de remplacement à cartouche venant s'ajouter aux exigences de l'IEC 60127-1. Cette troisième édition de l'IEC 60127-2 annule et remplace la deuxième édition, parue en 2010. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: ajout de 4 feuilles de norme 7 à 10. Mots clés: éléments de remplacement à cartouche pour coupe-circuit miniatures, la protection d'appareils électriques, de matériels électroniques et de leurs composants
Cette publication doit être lue conjointement avec la CEI 60127-1:2006.

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
