26、ON _ HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES SAFETY Part 2-24: Particular requirements for refrigerating appliances, ice-cream appliances and ice-makers FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electro

27、technical committees (IEC National Committees). The 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 Specificat

28、ions, Technical Reports, 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

29、, governmental and non-governmental organizations liaising 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 deci

30、sions or agreements 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 interested IEC National Committees. 3) IEC Publications have the form of recommendations for inter

31、national 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 accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In or

32、der to promote international uniformity, IEC National 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 cl

33、early indicated 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

34、 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 agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, pro

35、perty 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, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in

36、 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 of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying an

37、y or all such patent rights. This part of International Standard IEC 60335 has been prepared by subcommittee 61C: Household appliances for refrigeration, of IEC technical committee 61: Safety of household and similar electrical appliances. This seventh edition cancels and replaces the sixth edition

38、published in 2002 including its Amendment 1 (2005) and Amendment 2 (2007). It constitutes a technical revision. The principal changes in this edition as compared with the previous edition of IEC 60335-2-24 are as follows (minor changes are not listed): aligns the text with IEC 60335-1, and its Amend

39、ments 1 and 2; clarifies the term “household and similar use” (1, 7.12); updates marking requirements for supply terminals of battery operated appliances (7.6, 7.101); 60335-2-24 IEC:2010 5 introduces requirements for appliances using transcritical refrigerant systems (3.112, 3.113, 3.114, 3.115, 3.

40、116, 7.1, 7.6, 7.12.1, 22.103, 24.1.4, 24.102); introduces an enhanced flexing test (23.3); introduces requirements for accessible glass panels (22.116); clarifies tests for appliances using flammable refrigerants (22.107, Annex DD) The text of this standard is based on the following documents: FDIS

41、 Report on voting 61C/459/FDIS 61C/461/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/IEC Directives, Part 2. This part 2 is to be used in conjunction

42、 with the latest edition of IEC 60335-1 and its amendments. It was established on the basis of the fourth edition (2001) of that standard. NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60335-1. This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as

43、 to convert that publication into the IEC standard: Safety requirements for electric refrigerating appliances, ice-cream appliances and ice-makers. When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies as far as is reasonable. When this standard states “additi

44、on“, “modification“ or “replacement“, the relevant text in Part 1 is to be adapted accordingly. NOTE 2 The following numbering system is used: subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1; unless notes are in a new subclause or involve notes in

45、 Part 1, they are numbered starting from 101, including those in a replaced clause or subclause; additional annexes are lettered AA, BB, etc. NOTE 3 The following print types are used: requirements: in roman type; test specifications: in italic type; notes: in smaller roman type. Words in bold in th

46、e text are defined in Clause 3. When a definition concerns an adjective, the adjective and the associated noun are also in bold. A list of all parts of the IEC 60335 series, under the general title: Household and similar electrical appliances Safety, can be found on the IEC website. The committee ha

47、s decided that the contents of the base publication and its amendments 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

48、 a revised edition, or amended. 6 60335-2-24 IEC:2010 NOTE 4 The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in

49、 accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months or later than 36 months from the date of publication. The following differences exist in the countries indicated below. 22.101：
