    17、cal 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

    18、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 Co

    19、mmittee 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

    20、 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 a

    21、ll 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

    22、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 dive

    23、rgence 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

    24、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 exp

    25、erts 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

    26、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

    27、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. This second edition cancels and replaces

    28、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. 4 IEC 60127-7:2015 IEC 2015 The text of this

    29、 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 has been drafted in accordance with the ISO/IEC Directives,

    30、 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: Definitions for miniature fuses and general requirements f

    31、or 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 subclause of IEC 60127-1 applies without modification as far a

    32、s 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 numbered AA, BB, etc. The committee has decided that the co

    33、ntents 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, replaced by a revised edition, or amended. A bilingual v

    34、ersion of this publication may be issued at a later date. IEC 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 to miniature fuses should have the same publication number in order to facil

    35、itate 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

    36、, 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-miniat

    39、inks for special applications 1 Scope This part of IEC 60127 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 exce

    40、eding 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 r

    41、equirements 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 al

    42、low verification of the values (for example melting time and breaking capacity values) specified by the manufacturer. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
