18、organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activi

19、ties, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also pa

20、rticipate in this preparation. The IEC collaborates closely with the InternationalOrganization for Standardization (ISO) in accordance with conditions determined by agreement between thetwo organizations.2) The formal decisions or agreements of the IEC on technical matters express, as nearly as poss

21、ible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3) The documents produced have the form of recommendations for international use and are published in the formof standards, technical specifica

22、tions, technical reports or guides and they are accepted by the NationalCommittees in that sense.4) In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standar

23、ds. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its st

24、andards.6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights. The 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 sub

25、committee 61E:Safety of electrical commercial catering equipment, of IEC technical committee 61: Safety ofhousehold and similar electrical appliances.This fourth edition cancels and replaces the third edition published in 2000. It constitutes atechnical revision.The text of this part of IEC 60335 is

26、 based on the following documents:FDIS Report on voting61E/403/FDIS 61E/415/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and itsamen

27、dments. 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 toconvert that publication into the IEC standard: Saf

28、ety requirements for commercial electricboiling pans.Copyright International Electrotechnical Commission Provided by IHS under license with IECNot for ResaleNo reproduction or networking permitted without license from IHS-,- 4 60335-2-47 IEC:2002(E)When a particular subclause of Part 1 is not mentio

29、ned in this part 2, that subclause appliesas far as is reasonable. When this standard states “addition“, “modification“ or “replacement“, therelevant 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 f

30、rom 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, includingthose in a replaced clause or subclause; additional annexes are lettered AA, BB, etc.NOTE 3 The following print types are used: requirements: in ro

31、man 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 1 concerns an adjective, theadjective and the associated noun are also in bold .The committee has decided that the contents of this publication will

32、remain unchanged until2004. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended.The following differences exist in the countries indicated below. 6.1: Class 01 appliances are allowed (Japan). 6.2: For appliances intended to be installed in a kitche

33、n, an appropriate degree of protection against harmfulingress of water is required according to their height of installation (France). 13.2: Leakage current limits are different (Japan). 16.2: Leakage current limits are different (Japan). Clause 21: For appliances intended to be installed in a kitch

34、en, different values of impact energy areapplicable according to the height of the impact point (France).A bilingual version of this publication may be issued at a later date.Copyright International Electrotechnical Commission Provided by IHS under license with IECNot for ResaleNo reproduction or ne

36、ted level of protection against hazards suchas electrical, mechanical, thermal, fire and radiation of appliances when operated as innormal use taking into account the manufacturers instructions. It also covers abnormalsituations that can be expected in practice.This standard takes into account the r

37、equirements of IEC 60364 as far as possible so thatthere is compatibility with the wiring rules when the appliance is connected to the supplymains. However, national wiring rules may differ.If an appliance within the scope of this standard also incorporates functions that are coveredby another part

38、2 of IEC 60335, the relevant part 2 is applied to each function separately, asfar as is reasonable. If applicable, the influence of one function on the other is taken intoaccount.This standard is a product family standard dealing with the safety of appliances and takesprecedence over horizontal and

39、generic standards covering the same subject.An appliance that complies with the text of this standard will not necessarily be considered tocomply with the safety principles of the standard if, when examined and tested, it is found tohave other features that impair the level of safety covered by thes

40、e requirements.An appliance employing materials or having forms of construction differing from those detailedin the requirements of this standard may be examined and tested according to the intent ofthe requirements and, if found to be substantially equivalent, may be considered to complywith the st

42、al electric boiling pans1 ScopeThis clause of Part 1 is replaced by the following.This International Standard deals with the safety of electrically operated commercial boilingpans not intended for household use, their rated voltage being not more than 250 V forsingle-phase appliances connected betwe

43、en one phase and neutral, and 480 V for otherappliances.NOTE 101 These appliances are used, for example, in restaurants, canteens, hospitals and commercialenterprises such as bakeries, butcheries, etc.The electrical part of appliances making use of other forms of energy is also within the scopeof th

44、is standard.As far as is practicable, this standard deals with the common hazards presented by thesetypes of appliances.NOTE 102 Attention is drawn to the fact that for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may benecessary; in many countrie

45、s additional requirements are specified by the national health authorities, the nationalauthorities responsible for the protection of labour, the national water supply authorities and similar authorities; in many countries additional requirements are specified for pressure appliances.NOTE 103 This s

46、tandard does not apply to appliances designed exclusively for industrial purposes; appliances intended to be used in locations where special conditions prevail, such as the presence of acorrosive or explosive atmosphere (dust, vapour or gas); continuous process appliances for the mass production of

47、food;2 Normative referencesThis clause of Part 1 is applicable.3 DefinitionsThis clause of Part 1 is applicable except as follows.3.1.4 Addition:NOTE 101 The rated power input is the sum of the power inputs of all the individual elements in the appliancethat can be on at one time; where there are se

48、veral such combinations possible, that giving the highest power inputis used in determining the rated power input.Copyright International Electrotechnical Commission Provided by IHS under license with IECNot for ResaleNo reproduction or networking permitted without license from IHS-,-60335-2-47 IEC:2002(E) 7 3.1.9 Replacement:normal operationoperation of the appliance under the following conditionsThe appliance is filled with water at 15 C 5 C to the indicated level.Appliances with more than one programme are operated with the most severe programme.
