31、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

32、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 comm

33、ittees; 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 f

34、or 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 committe

35、e 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 ac

36、curate, 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 regi

37、onal 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

38、 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 agen

39、ts 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,

40、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 o

41、f 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. DISCLAIMER This Redline version is not an official IEC Standard and is intended only to provide the user with an indication of what changes hav

42、e been made to the previous version. Only the current version of the standard is to be considered the official document. This Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition. A vertical bar appears in the margin whereve

43、r a change has been made. Additions are in green text, deletions are in strikethrough red text. 6 IEC 61951-2:2017 RLV IEC 2017 International Standard IEC 61951-2 has been prepared by subcommittee 21A: Secondary cells and batteries containing alkaline or other non-acid electrolytes, of IEC technical

44、 committee 21: Secondary cells and batteries. This fourth edition cancels and replaces the third edition published in 2011 of which it constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: addition of battery type; a

45、ddition of F (high recovery type) designation for cells and batteries; addition of I (low self-discharge type) designation for cells; revision of Figure 3 (6.1.3.1); addition of “optional pip” note to positive contact; changed leader line position from pip to flats of positive contact (B and G). The

46、 text of this standard is based on the following documents: FDIS Report on voting 21A/623/FDIS 21A/629/RVD 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/

47、IEC Directives, Part 2. A list of all parts of the IEC 61951 series can be found, under the general title Secondary cells and batteries containing alkaline or other non-acid electrolytes Secondary sealed cells and batteries for portable applications, on the IEC website. The committee has decided tha

48、t 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, replaced by a revised edition, or amended. IMPOR
