31、R HOUSEHOLD USE METHODS FOR MEASURING THE PERFORMANCE 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-operat
32、ion 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 Specifications (PAS) and Guides (hereafter referred to as “
33、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 liaising with the IEC also participate in this prepa
34、ration. 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 express, as nearly as possible, an international conse
35、nsus 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 Committees in that sense. While all reasonable efforts a
36、re 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 National Committees undertake to apply IEC Publications t
37、ransparently 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 not provide any attestation of conformity. Independe
38、nt 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 the latest edition of this publication. 7) No liabi
39、lity 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 whatsoever, whether direct or indirect, or for costs (inclu
40、ding 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 publications is indispensable for the correct application of
41、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. International Standard IEC 61121 has been prepared by subcommittee 59D: H
42、ome laundry appliances, of IEC technical committee 59: Performance of household and similar electrical appliances. This fourth edition cancels and replaces the third edition published in 2002 and Amendment 1 (2005). This edition constitutes a technical revision. This edition includes the following s
43、ignificant technical changes with respect to the previous edition: a) General: more terms have been defined and some previous definitions have been streamlined, in addition to the correction of some symbols and equations; where possible, definitions and terms have been used in common with IEC 60456:
44、2010; the content has been organised into a more logical and simple structure, and repetitive sections have been removed. 6 61121 IEC:2012 b) Conditions of measurement: the wording of various sections has been revised to reduce ambiguity; limits have been defined for water characteristics for automa
45、tic tumble dryers that are sensitive to conductivity as well as methods to adjust these characteristics where necessary. c) Reproducibility and repeatability of test results: revision of the specification for the cotton test load to include suitable test materials which are currently available on th
46、e market; more careful definition of the process and conditions for pre-treatment, conditioning and normalization. d) Test methods: accuracy of measurement has been defined for all instruments; limits and interpretations of the allowable final moisture content for each type of dryer are now defined;
47、 practical advice regarding the test procedure has been given with the aim of reducing ambiguity. Words in bold in the text are defined in Clause 3. This bilingual version (2013-07) corresponds to the monolingual English version, published in 2012-02. The text of this standard is based on the follow
48、ing documents: FDIS Report on voting 59D/393/FDIS 59D/395/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. The French version of this standard has not been voted upon. This publication has been drafted in accordan
49、ce with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site 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. 61121 IEC:2012 7 I
