31、HNOLOGIES Part 7-1: Test methods Single cell performance tests for polymer electrolyte fuel cells (PEFC) FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The
32、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 Specific
33、ations (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 l
34、iaising 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 exp
35、ress, 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 Commi
36、ttees 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 Nation
37、al 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 n
38、ot 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
39、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 whatsoev
40、er, 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 publicatio
41、ns 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. The main task of IEC t
42、echnical committees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a Technical Specification when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts, or the subj
43、ect is still under technical development or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. Technical Specifications are subject to review within three years of publication to decide whether they can be transformed into Inte
44、rnational Standards. IEC TS 62282-7-1, which is a Technical Specification, has been prepared by IEC technical committee 105: Fuel cell technologies. PD IEC/TS 62282-7-1:2017 8 IEC TS 62282-7-1:2017 IEC 2017 This second edition cancels and replaces the first edition published in 2010. This edition co
45、nstitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of new tests, mainly regarding transportation applications; and, b) restructuring of the format: basic and applied performance test methods. The text of
46、 this Technical Specification is based on the following documents: Enquiry draft Report on voting 105/568/DTS 105/621/RVC Full information on the voting for the approval of this technical specification can be found in the report on voting indicated in the above table. This document has been drafted
47、in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 62282 series, published under the general title: Fuel cell technologies, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date i
48、ndicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be transformed into an International standard, reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may
49、be issued at a later date. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer.
