19、wide 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 standardization in the electrical and electronic fields. To this end and in addition to other ac
20、tivities, IEC publishes 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 subje
21、ct 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 with the International Organization for Standardization (ISO) in accordance with conditions det
22、ermined 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 subjects since each technical committee has representation from all interested IEC National Comm
23、ittees. 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 technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in whic
24、h 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 possible in their national and regional publications. Any divergence between any IEC Publicat
25、ion 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 conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not
26、 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 directors, employees, servants or agents including individual experts and members of its technic
27、al 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 arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Pu
28、blications. 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 drawn to the possibility that some of the elements of this IEC Publication may be the subject
29、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 IEC technical committee 61: Safety of household and similar electrical appliances. This sixth edition cancels and replaces the fifth e
30、dition published in 2002 including its Amendment 1 (2008) and its Amendment 2 (2011). It constitutes a technical revision. The principle changes in this edition as compared with the fifth edition of IEC 60335-2-37 are as follows (minor changes are not listed): stating some wording in the scope more
31、precisely; addition of a measurement method for pans in the definition for normal operation; new definitions on the topic surface temperature; deletion of the paragraph with the warning for dangerous voltages (already covered by Part 1); IEC 60335-2-37:2017 IEC 2017 5 addition of hot surface symbol
32、IEC 60417-5041; addition of instructions and markings on hot surfaces and other topics; addition of requirements, measuring methods and thresholds for different materials on hot surfaces; modification on leakage current defining the value for appliances with a power consumption less than 1 kW; modif
33、ication on the criteria for the stability test; addition of a requirement for the construction of stationary appliances with rollers or castors; modification on some points concerning permanent connection to fixed wiring; addition of specific requirements concerning types of screws to be used for el
34、ectrical connections and connections for earth continuity; addition of a figure showing the surfaces to be measured; addition of a figure showing the probe for measuring surface temperatures; addition of informative Annex P dealing with leakage currents for appliances used in tropical climates. The
35、text of this Standard is based on the following documents: FDIS Report on voting 61/5328/FDIS 61/5384/RVD Full information on the voting for the approval of this International Standard can be found in the report on voting indicated in the above table. This document has been drafted in accordance wit
36、h the ISO/IEC Directives, Part 2. 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. This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments. It was esta
37、blished on the basis of the fifth edition (2010) 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 to convert that publication into the IEC standard: Safety requirements
38、for commercial electric doughnut fryers and deep fat fryers. 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 text in part 1 is to be adapted acco
39、rdingly. 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 Part 1, they are numbered starting from 101, including those in a replaced clause or s
40、ubclause; additional annexes are lettered AA, BB, etc. NOTE 3 The following print types are used: 6 IEC 60335-2-37:2017 IEC 2017 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 of Part
41、1 concerns an adjective, the adjective and the associated noun are also in bold. The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific document. At thi
42、s date, the document 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 testing organizations may need a transitional period following publication of a new, amended or revised IE
43、C 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 content of this publication be adopted for implementation nationally not earlier than 12 months from the dat
44、e of publication. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. IEC 60335-2-37:2017 IEC 2017
45、 7 INTRODUCTION It has been assumed in the drafting of this International Standard that 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, mecha
46、nical, thermal, fire and radiation of appliances when operated as in normal use taking 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 a
47、ppliances. 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 supply mains. However, national wiring rules may differ. If an appliance within the scope of this standard also inc
48、orporates functions that are covered by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as far as is reasonable. If applicable, the influence of one function on the other is taken into account. This standard is a product family standard dealing with the safet
49、y of appliances and takes precedence over horizontal and generic standards covering the same subject. NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into consideration when developing the general and particular requirements for the IEC 60335 series of standards. For example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as ISO 13732-1 for hot surf
