24、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

25、 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 t

26、o 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

27、 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 tec

28、hnical 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 Pub

29、lications 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 na

30、tional 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 s

31、ervices 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, s

32、ervants 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 public

33、ation, 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 possibil

34、ity 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.

35、 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

36、5. The text of this standard is based on the following documents: FDIS Report on voting 32C/526/FDIS 32C/530/RVD BS EN 60127-5:2017 4 IEC 60127-5:2016 IEC 2016 Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This pub

37、lication 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 th

38、e 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, replaced by a revised edition, or amended. BS EN 60127-5:2017IEC 60127-5:2016 IEC 2016 5 INTRODUCTION According t

39、o 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

40、 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

44、ks 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

45、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

46、) 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 i
