40、2010(E) 7 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ CLOTHES WASHING MACHINES FOR 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 (
41、IEC National Committees). The object of IEC is to promote interna- tional 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, Techni- cal Re
42、ports, Publicly Available Specifications (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
43、 non-governmental organiza- tions liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Or- ganization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agree
44、ments 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 all inter- ested IEC National Committees. 3) IEC Publications have the form of recommendations for international use
45、 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 responsible for the way in which they are used or for any misinter- pretation by any end user. 4) In order to pro
46、mote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence be- tween any IEC Publication and the corresponding national or regional publication shall be clearly in
47、dicated 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 marks of conformity. IEC is not responsible for any services carried out by independent certification bodies.
48、 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 experts and members of its technical committees and IEC National Committees for any personal injury, property da
49、mage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and ex- penses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publica- tions. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for th
