24、 APPLIANCES Part 2: Hobs Methods for measuring performance 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-o

25、peration 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 Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to

26、 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, governmental and non-governmental organizations liaising with the IEC also participate in this p

27、reparation. IEC collaborates closely with 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 c

28、onsensus 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 international use and are accepted by IEC National Committees in that sense. While all reasonable effor

29、ts 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 order to promote international uniformity, IEC National Committees undertake to apply IEC Publicatio

30、ns 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 clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Indep

31、endent 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 bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No l

32、iability 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, whether direct or indirect, or for costs (i

33、ncluding 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 indispensable for the correct application

34、 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 60350-2 has been prepared by subcommittee

35、59K: Ovens and microwave ovens, cooking ranges and similar appliances, of IEC technical committee 59: Performance of household and similar electrical appliances. This first edition of IEC 60350-2 is related to IEC 60350:1999 which shall be separated in two parts: one part for cooking ranges, ovens a

36、nd steam ovens and the other part for hobs. This part 2 of IEC 60350 covers hobs, and IEC 60350-1 covers ovens. This edition includes the following significant technical changes with respect to IEC 60350:1999: A measurement procedure for measuring the smallest detected diameter for induction hobs (s

37、ee 7.5). IEC 60350:1999 will be withdrawn after the publication of IEC 60350-1 and IEC 60350-2. In this standard, terms in bold characters are defined in Clause 3. 60350-2 IEC:2011 5 The text of this standard is based on the following documents: FDIS Report on voting 59K/233/FDIS 59K/236/RVD Full in

38、formation 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. A list of all the parts in the IEC 60350 series, under the general title Household electri

39、c cooking appliances, 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 the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publica

40、tion will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 60350-2 IEC:2011 HOUSEHOLD ELECTRIC COOKING APPLIANCES Part 2: Hobs Methods for measuring performance 1 Scope This part of IEC 60350 defines methods for measuring the performance of electric hobs for household use. NOT

41、E 1 Appliances covered by this standard may be built-in or for placing on a working surface or the floor. The hob can also be a part of a cooking range. NOTE 2 This standard does not apply to portable appliances for cooking, grilling and similar functions (IEC 61817). This standard defines the main

42、performance characteristics of these appliances which are of interest to the user and specifies methods for measuring these characteristics. NOTE 3 Some of the tests which are specified in this standard are not considered to be reproducible since the results may vary between laboratories. They are t

43、herefore intended for comparative testing purposes only. This standard does not specify requirements for performance. NOTE 4 This standard does not deal with safety requirements (IEC 60335-2-6 and IEC 60335-2-9). 2 Normative references The following referenced documents are indispensable for the app

44、lication of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 62301:20051, Household electrical appliances Measurement of standby power 3 Terms and definitions For the pur

45、poses of this document, the following terms and definitions apply. 3.1 cooking range appliance having a hob and at least one oven. It may incorporate a grill NOTE Methods for measuring performance of ovens are described in IEC 60350-1. 3.2 hob appliance or part of an appliance which incorporates one

46、 or more cooking zones NOTE A hob is also known as a cooktop. 3.3 cooking zone part of the hob or area marked on the surface of a hob on which pans are placed for heating _ 1This document has been replaced by a new edition (2011), but for the purposes of this standard, the 2005 edition is cited. 603
