23、n for standardization comprising all national electrotechnical 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 pu
24、blishes International Standards, Technical Specifications, 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 ma
25、y participate in this preparatory work. International, 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 agreem
26、ent 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 subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Pu
27、blications 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 technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used o
28、r 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 possible in their national and regional publications. Any divergence between any IEC Publication and the corre
29、sponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the l
30、atest 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 damage or other damage of any nature whatsoever, w
31、hether 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 this publication. Use of the referenced publications is
32、 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 any or all such patent rights. International Standard IEC
33、60335-2-4 has been prepared by IEC technical committee 61: Safety of household and similar electrical appliances. This sixth edition cancels and replaces the fifth edition published in 2002 including its Amendment 1 (2004) and Amendment 2 (2006). It constitutes a technical revision. The principal ch
34、anges in this edition as compared with the fifth edition of IEC 60335-2-4 are as follows (minor changes are not listed): aligns the text with IEC 60335-1:2001, and its Amendments 1 and 2; clarifies criteria for the protection against mechanical hazards for double lid appliances (20.103 and 20.104);
35、some notes have been converted to normative text (Clause 1, 20.102 and Annex AA). 4 60335-2-4 IEC:2008 The text of this standard is based on the following documents: FDIS Report on voting 61/3677/FDIS 61/3697/RVD Full information on the voting for the approval of this standard can be found in the re
36、port 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 with the latest edition of IEC 60335-1 and its amendments. It was established on the basis of the fourth edition (2001) of that s
37、tandard. 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 electric spin extractors. NOTE 2 The following annex c
38、ontain provisions suitably modified from another IEC standard: Annex AA Rinsing agent IEC 60436 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 “addition“, “modification“ or “replacement“, the relevant t
39、ext in Part 1 is to be adapted accordingly. NOTE 3 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 Part 1, they are numbered starting from 101, includ
40、ing those in a replaced clause or subclause; additional annexes are lettered AA, BB, etc. NOTE 4 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 conc
41、erns 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 has decided that the contents of the base publication an
42、d its amendments will remain unchanged until the maintenance result 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. 60335-2-4 IEC
43、:2008 5 NOTE 5 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 accordance with the new requirements and to e
44、quip 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 countri
45、es indicated below. 3.1.9: As an alternative to the test material specified, pieces of cloth having an area between 4 800 cm2and 5 000 cm2, with one side at least 55 cm, may be used for the tests (USA). 6.1: Class 0I appliances are allowed (Japan). 6.2: IPX0 appliances are allowed (USA). 15.2: The t
46、est is different (USA). 18: The test is carried out for 6 000 cycles (Canada and USA). 19.7: This subclause is applicable (USA). 20.101: The test is not carried out (USA). 20.103: The requirement is different (USA). 20.104: The requirement is different (USA). 21.101: There are constructional require
47、ments for metal lids and the tests are different for thermoplastic lids (USA) 21.102: There are constructional requirements for metal lids and the tests are different for thermoplastic lids (USA). 6 60335-2-4 IEC:2008 INTRODUCTION It has been assumed in the drafting of this International Standard th
48、at the execution of its provisions is entrusted to appropriately qualified and experienced persons. This standard recognizes the internationally accepted level of protection against hazards such as electrical, mechanical, thermal, fire and radiation of appliances when operated as in normal use takin
49、g into account the manufacturers instructions. It also covers abnormal situations that can be expected in practice and takes into account the way in which electromagnetic phenomena can affect the safe operation of appliances. This standard takes into account the requirements of IEC 60364 as far as possible so that there is compatibility with the wiring rules when the appliance is connected to the suppl
