26、t unit or compressor 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-operation on all questions concerning s
27、tandardization 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 “IEC Publication(s)”). Their prepa
28、ration 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 preparation. IEC collaborates closely w
29、ith 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 consensus of opinion on the relevant su
30、bjects 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 are made to ensure that the technic
31、al 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 transparently to the maximum extent
32、 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. Independent certification bodies provide co
33、nformity 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 liability shall attach to IEC or its di
34、rectors, 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 (including legal fees) and expenses aris
35、ing 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 this publication. 9) Attention is
36、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. This part of International Standard IEC 60335 has been prepared by subcommittee 61C: Household appliances f
37、or refrigeration, of IEC technical committee 61: Safety of household and similar electrical appliances. This second edition cancels and replaces the first edition published in 2002 including its Amendment 1 (2005) and amendment 2 (2007). It constitutes a technical revision. The principal changes in
38、this edition as compared with the first edition of IEC 60335-2-89 are as follows (minor changes are not listed): aligns the text with IEC 60335-1, and its Amendments 1 and 2; introduces requirements for appliances using transcritical refrigerant systems (3.107, 3.108, 3.109, 3.110, 3.111, 7.1, 7.6,
39、7.12.1, 22.103, 24.1.4, 24.102) introduces an enhanced flexing test (23.3) 60335-2-89 IEC:2010 5 The text of this standard is based on the following documents: FDIS Report on voting 61C/208/FDIS 61C/211/RVD Full information on the voting for the approval of this standard can be found in the report o
40、n 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 with the latest edition of IEC 60335-1 and its amendments. It was established on the basis of the fourth edition (2001) of that standar
41、d. 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 to convert that publication into the IEC standard: Safety requirements for commercial refrigerating appliances with an incorporated or
42、remote refrigerant unit or compressor. Where a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies as far as is reasonable. Where this standard states “addition“, “modification” or “replacement“, the relevant text in Part 1 is to be adapted accordingly. NOTE 2 The
43、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 Part 1, they are numbered starting from 101, including those in a replaced clause or subclause; additional
44、 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 small roman type. Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the associated nou
45、n 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 has decided that the contents of this publication will remain unchanged until the stability date indicated on t
46、he 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. NOTE 4 The attention of National Committees is drawn to the fact that equipment manufacturers and te
47、sting organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the cont
48、ent 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. 6 60335-2-89 IEC:2010 22.101: E12 and E17 lamp holders are checked as specified for E14
49、and B15 lamp holders. E26 lamp holder is checked as specified for E27 and B22 lamp holders (Japan). 22.109: For unsealed glass tube heaters, the temperature requirements are different (Japan).
