Miniature fuses - Part 7: Miniature fuse-links for special applications
IEC 60127-7:2015(E) covers requirements for miniature fuse-links for special applications. This part of IEC 60127 is applicable to fuse-links with a rated voltage not exceeding 1 000 V, a rated current not exceeding 20 A and a rated breaking capacity not exceeding 50 kA. It does not apply to fuses completely covered by the subsequent parts of IEC 60269-1. It does not apply to miniature fuse-links for appliances intended to be used under special conditions, such as in corrosive or explosive atmospheres. This part of IEC 60127 applies in addition to the requirements of IEC 60127-1. Miniature fuse-links for special applications are not intended to be replaced by the end-user of an electrical/electronic appliance. The object of this part of IEC 60127 is to establish uniform test methods for miniature fuse-links for special applications, so as to allow verification of the values (for example melting time and breaking capacity values) specified by the manufacturer. This second edition cancels and replaces the first edition published in 2013. This edition includes the following significant technical changes with respect to the previous edition: - defining a test board for surface mount fuse-links, Figure 2; - defining test schedules for homogenous series. This publication is to be read in conjunction with IEC 60127-1:2006. Keywords: fuse-links with a rated voltage not exceeding 1 000 V, a rated current not exceeding 20 A and a rated breaking capacity not exceeding 50 kA.

Coupe-circuit miniatures - Partie 7: Eléments de remplacement miniatures pour applications spéciales
IEC 60127-7:2015 couvre des exigences pour des éléments de remplacement miniatures pour applications spéciales. La présente partie de l'IEC 60127 est applicable aux éléments de remplacement de tension assignée ne dépassant pas 1 000 V, de courant assigné ne dépassant pas 20 A et de pouvoir de coupure assigné ne dépassant pas 50 kA. Elle ne s'applique pas aux coupe-circuit complètement couverts par les autres parties de l'IEC 60269-1. Elle n'est pas applicable aux éléments de remplacement miniatures placés dans des appareils destinés à être employés dans des conditions particulières, comme dans des atmosphères corrosives ou explosives. La présente partie de l'IEC 60127 s'applique en complément des exigences de l'IEC 60127-1. Les éléments de remplacement miniatures pour applications spéciales ne sont pas destinés à être remplacés par l'utilisateur final d'un appareil électronique ou électrique. L’objet de la présente partie de l'IEC 60127 est d'établir des méthodes d'essai uniformes pour des éléments de remplacement miniatures pour applications spéciales, pour permettre de vérifier les valeurs (par exemple la durée de fusion et le pouvoir de coupure) spécifiées par le fabricant. Cette deuxième édition annule et remplace la première édition, parue en 2013. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - définition d'une carte d'essai pour éléments de remplacement à montage en surface, Figure 2; - définition des programmes d'essai pour les séries homogènes. La présente Norme internationale doit être utilisée conjointement avec l'IEC 60127-1:2006 Mots clés: éléments de remplacement de tension assignée ne dépassant pas 1 000 V, courant assigné ne dépassant pas 20 A et de pouvoir de coupure assigné ne dépassant pas 50 kA.
Miniaturne varovalke - 7. del: Miniaturni taljivi vložki za posebne namene (IEC 60127-7:2015)
Ta del standarda IEC 60127 zajema zahteve za miniaturne taljive vložke za posebno uporabo. Ta del standarda IEC 60127 se uporablja za taljive vložke z nazivno napetostjo, ki ne presega 1000 V, nazivnim tokom, ki ne presega 20 A, in nazivno zmogljivostjo prekinitve, ki ne presega 50 kA. Ne uporablja se za varovalke, ki so v celoti obravnavane v nadaljnjih delih standarda IEC 60269-1. Ne uporablja se za miniaturne taljive vložke za aparate, namenjene za uporabo pod posebnimi pogoji, npr. v korozivni ali eksplozivni atmosferi.
Ta del standarda IEC 60127 se poleg tega uporablja za zahteve iz standarda IEC 60127-1. Za miniaturne taljive vložke za posebno uporabo ni predvideno, da jih zamenja končni uporabnik električnega/elektronskega aparata.
Namen tega dela standarda IEC 60127 je vzpostaviti enotne preskusne metode za miniaturne taljive vložke za posebno uporabo, tako da se omogoči preverjanje vrednosti (na primer čas taljenja in vrednosti zmogljivosti prekinitve), ki jih določi proizvajalec.

MINIATURE FUSES –
Part 7: Miniature fuse-links for special applications
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 pub
