67 HOUSEHOLD AND SIMILAR ELECTRICAL RICE COOKERS–
68 METHODS FOR MEASURING THE PERFORMANCE
70 FOREWORD
72 1) The International Electrotechnical Commission (IEC) is a worldwide organization for
73 standardization comprising all national electrotechnical committees (IEC National
74 Committees). The object of IEC is to promote international co-operation on all questions
75 concerning standardization in the electrical and electronic fields. To this end and in addition
76 to other activities, IEC publishes International Standards, Technical Specifications,
77 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to
78 as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC
79 National Committee interested in the subject dealt with may participate in this preparatory
80 work. International, governmental and non-governmental organizations liaising with the IEC
81 also participate in this preparation. IEC collaborates closely with the International
82 Organization for Standardization (ISO) in accordance with conditions determined by
83 agreement between the two organizations.
84 2) The formal decisions or agreements of IEC on technical matters express, as nearly as
85 possible, an international consensus of opinion on the relevant subjects since each technical
86 committee has representation from all interested IEC National Committees.
87 3) IEC Publications have the form of recommendations for international use and are accepted
88 by IEC National Committees in that sense. While all reasonable efforts are made to ensure
89 that the technical content of IEC Publications is accurate, IEC cannot be held responsible
90 for the way in which they are used or for any misinterpretation by any end user.
91 4) In order to promote international uniformity, IEC National Committees undertake to apply
92 IEC Publications transparently to the maximum extent possible in their national and regional
93 publications. Any divergence between any IEC Publication and the corresponding national
94 or regional publication shall be clearly indicated in the latter.
95 5) IEC itself does not provide any attestation of conformity. Independent certification bodies
96 provide conformity assessment services and, in some areas, access to IEC marks of
97 conformity. IEC is not responsible for any services carried out by independent certification
98 bodies.
99 6) All users should ensure that they have the latest edition of this publication.
100 7) No liability shall attach to IEC or its directors, employees, servants or agents including
101 individual experts and members of its technical committees and IEC National Committees
102 for any personal injury, property damage or other damage of any nature whatsoever, whether
103 direct or indirect, or for costs (including legal fees) and expenses arising out of the
104 publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
105 8) Attention is drawn to the normative references cited in this publication. Use of the referenced
106 publications is indispensable for the correct application of this publication.
107 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may
108 be the subject of patent rights. IEC shall not be held responsible for identifying any or all
109 such patent rights.
