29、REWORD 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 e

30、lectrical 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

31、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 O

32、rganization 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 techn

33、ical 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 Publi

34、cations 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 nati

35、onal 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 ser

36、vices 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, ser

37、vants 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 publicat

38、ion, 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 possibilit

39、y 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 60127-7 has been prepared by subcommittee 32C: Miniature fuses, of IEC technical committee 32: Fuses. T

40、his 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: a) defining a test board for surface mount fuse-links, Figure 2; b) defining test schedules for homogenous series. BS E

41、N 60127-7:2016 4 IEC 60127-7:2015 IEC 2015 The text of this standard is based on the following documents: CDV Report on voting 32C/507/CDV 32C/513/RVC 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 publication

42、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. This International Standard is to be used in conjunction with IEC 60127-1:2006, Miniature fuses Part 1:

43、 Definitions for miniature fuses and general requirements for miniature fuse-links and its Amendment 1 (2011). The clauses of this standard supplement, modify or replace the corresponding clauses in IEC 60127-1. Where there is no corresponding clause or subclause in this standard, the clause or subc

44、lause of IEC 60127-1 applies without modification as far as is reasonable. When this standard states “addition” or “replacement”, the relevant text in IEC 60127-1 is to be adapted accordingly. Subclauses which are additional to those in Part 1 are numbered starting from 101. Additional annexes are n

45、umbered AA, BB, etc. 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

46、, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. BS EN 60127-7:2016IEC 60127-7:2015 IEC 2015 5 INTRODUCTION According to the wish expressed by the users of miniature fuses, all standards, recommendations and other documents relating

47、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 clause

48、s 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

49、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 60127-8,
