Miniature fuses - Part 5: Guidelines for quality assessment of miniature fuse-links

IEC 60127-5:2016 gives a guide for tests for assessing the quality of miniature fuse-links other than type tests, for the case where there is no complete agreement between the user and the manufacturer on what such tests apply. This document provides guidelines and limits generally acceptable for quality control purposes by large scale users and manufacturers of miniature fuse-links. This document has validity for large scale series with lot sizes of 10 000 and more. It is also applicable for smaller lot sizes, if necessary. Periodic inspections by reduced type tests (Clause 5) are intended to be carried out periodically in order to ensure that the level of technical performance previously verified by complete type tests as given in subsequent parts of the IEC 60127 series is maintained. The frequency of periodic in relation to lot-by-lot inspections is not established in this document. This second edition cancels and replaces the first edition published in 1988. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- addition of new tables in 4.3;
- addition of new tables in Clause 5.
Keywords: quality of miniature fuse-links

Coupe-circuit miniatures - Partie 5: Lignes directrices pour l'évaluation de la qualité des éléments de remplacement miniatures

L'IEC 60127-5:2016 constitue un guide pour les essais d'évaluation de la qualité des éléments de remplacement miniatures. Il ne s'agit pas d'essais de type. Ce document s'applique lorsque l'utilisateur et le fabricant ne parviennent pas à convenir des éléments sur lesquels de tels essais s'appliquent. Il s'agit de spécifier des lignes directrices et des limites nécessaires au contrôle de la qualité, généralement acceptables aussi bien pour les gros utilisateurs que pour les fabricants d'éléments de remplacement miniatures. Le présent document est applicable aux grandes séries d'un effectif de 10 000 lots et plus. Il s'applique également à des effectifs comportant moins de lots, si nécessaire. Des contrôles périodiques constitués par des essais de type réduits (Article 5) sont destinés à être réalisés régulièrement afin de garantir le maintien du niveau des performances techniques vérifié précédemment par tous les essais de type spécifiés dans les parties subséquentes de la série IEC 60127. La fréquence des contrôles périodiques par rapport aux contrôles lot par lot n'est pas établie dans le présent document. Cette deuxième édition annule et remplace la première édition parue en 1988. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- ajout de nouveaux tableaux en 4.3;
- ajout de nouveaux tableaux à l'Article 5.

Part 5: Guidelines for quality assessment of miniature fuse-links
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.

International Standard IEC 60127-5 has been prepared by subcommittee 32C: Miniature fuses,

of IEC technical committee 32: Fuses.

This second edition cancels and replaces the first edition published in 1988. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
a) addition of new tables in 4.3;
b) addition of new tables in Clause 5.
The text of this standard is based on the following documents:

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all parts in the IEC 60127 series, published under the general title Miniature fuses, can

be found on the IEC website.

The committee has decided that the contents of this publication will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,

INTRODUCTION
According to the wish expressed by the users of miniature fuses, all standards,

recommendations and other documents relating to miniature fuses should have the same

publication number in order to facilitate reference to fuses in other specifications, for example,

equipment specifications.

Furthermore, a single publication number and subdivision into parts would facilitate the

establishment of new standards, because clauses containing general requirements need not be

repeated.

The IEC 60127 series, under the general heading Miniature fuses, is thus subdivided as follows:

IEC 60127-1, Miniature fuses – Part 1: Definitions for miniature fuses and general requirements

for miniature fuse-links
IEC 60127-2, Miniature fuses – Part 2: Cartridge fuse-links
IEC 60127-3, Miniature fuses – Part 3: Sub-miniature fuse-links

IEC 60127-4, Miniature fuses – Part 4: Universal modular fuse-links (UMF) – Through-hole and

surface mount types

IEC 60127-5, Miniature fuses – Part 5: Guidelines for quality assessment of miniature fuse-links

IEC 60127-6, Miniature fuses – Part 6: Fuse-holders for miniature fuse-links

IEC 60127-7, Miniature fuses – Part 7: Miniature fuse-links for special applications

IEC PAS 60127-8, Miniature fuses – Part 8: Fuse resistors with particular overcurrent protection

MINIATURE FUSES –
Part 5: Guidelines for quality assessment of miniature fuse-links
1 Scope

This part of IEC 60127 gives a guide for tests for assessing the quality of miniature fuse-links

other than type tests, for the case where there is no complete agreement between the user and

the manufacturer on what such tests apply.

This document provides guidelines and limits generally acceptable for quality control purposes

by large scale users and manufacturers of miniature fuse-links. This document has validity for

large scale series with lot sizes of 10 000 and more. It is also applicable for smaller lot sizes, if

necessary.

Periodic inspections by reduced type tests (Clause 5) are intended to be carried out periodically

in order to ensure that the level of technical performance previously verified by complete type

tests as given in subsequent parts of the IEC 60127 series is maintained.

The frequency of periodic in relation to lot-by-lot inspections is not established in this document.
