16、Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end a

17、nd in addition to other activities, the IEC publishes International Standards. 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 organizati

18、ons liaising with the IEC also participate in this preparation. The 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 the IEC on technica

19、l matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested National Committees. 3) The documents produced have the form of recommendations for international use and are published in th

20、e form of standards, technical specifications, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent poss

21、ible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment

22、declared to be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. This part of Internation

23、al Standard IEC 60335 has been prepared by subcommittee 61E: Safety of electrical commercial catering equipment, of IEC technical committee 61: Safety of household and similar electrical appliances. It forms the first edition of IEC 60335-2-99. The text of this part of IEC 60335 is based on the foll

24、owing documents: FDIS Report on voting 61E/422/FDIS 61E/425/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments. It w

25、as 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 to convert it into the IEC standard: Safety requirements for co

26、mmercial electric hoods. 4 60335-2-99 IEC:2003(E) 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 accordingly. NO

27、TE 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 subclause; a

28、dditional 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 assoc

29、iated noun are also in bold. The committee has decided that the contents of this publication will remain unchanged until 2004. 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.

30、1: Class 01 hoods are allowed (Japan). 6.2: For hoods intended to be installed in a kitchen, an appropriate degree of protection against harmful ingress of water is required according to their height of installation (France). 13.2: Leakage current limits are different (Japan). 16.2: Leakage current

31、limits are different (Japan). Clause 21: For hoods intended to be installed in a kitchen, different values of impact energy are applicable according to the height of the impact point (France). A bilingual version of this publication may be issued at a later date.60335-2-99 IEC:2003(E) 5 INTRODUCTION

32、 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, mechanical, thermal,

33、 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. This standard takes into account the requirements of IEC 60364 as far as possible so that there is compatibility w

34、ith 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 incorporates functions that are covered by another part 2 of IEC 60335, the relevant part 2 is applied to each function separate

35、ly, 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 safety of appliances and takes precedence over horizontal and generic standards covering the same subject. An appliance that compl

36、ies with the text of this standard will not necessarily be considered to comply with the safety principles of the standard if, when examined and tested, it is found to have other features that impair the level of safety covered by these requirements. An appliance employing materials or having forms

37、of construction differing from those detailed in the requirements of this standard may be examined and tested according to the intent of the requirements and, if found to be substantially equivalent, may be considered to comply with the standard. 6 60335-2-99 IEC:2003(E) HOUSEHOLD AND SIMILAR ELECTR

38、ICAL APPLIANCES SAFETY Part 2-99: Particular requirements for commercial electric hoods 1 Scope This clause of Part 1 is replaced by the following. This International Standard deals with the safety of electrically operated commercial hoods intended for installation above commercial cooking appliance

39、s such as ranges, griddles, griddle grills and deep fat fryers, and not intended for household use, their rated voltage being not more than 250 V for single phase hoods connected between one phase and neutral, and 480 V for other hoods. Only single complete units and hoods supplied as separate parts

40、 which when assembled form a complete working hood, incorporating a fan, are within the scope of the standard. NOTE 101 Hoods are used, for example in restaurants, canteens, hospitals and commercial enterprises such as bakeries, butcheries, etc. The hood may be used above one or more appliance of th

41、e same or different types. So far as is practicable, this standard deals with the common hazards presented by these types of appliances. NOTE 102 Attention is drawn to the fact that: for hoods intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary; in

42、 many countries additional requirements including ventilation requirements are specified by the national health authorities, the national authorities responsible for the protection of labour and similar authorities; NOTE 103 This standard does not apply to: domestic range hoods (IEC 60335-2-31); pur

43、pose-built hoods, although this standard can be used as a guide (a purpose-built hood is either constructed on-site or specially constructed in the factory and is not mass produced); hoods not incorporating a fan; hoods designed exclusively for industrial purposes; hoods intended to be used in locat

44、ions where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas). NOTE 104 Requirements for hoods with externally mounted fans are under consideration. 2 Normative references This clause of Part 1 is applicable. 3 Definitions This clause of Par

45、t 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 hood which can be on at one time; where several such combinations are possible, that giving the highest power input is used in determining the rate

46、d power input.60335-2-99 IEC:2003(E) 7 3.1.9 Replacement: normal operation operation of the appliance under the following conditions The hood is operated after installation in accordance with the instructions, except that it is not connected to a duct. 3.101 hood motor-operated appliance intended to
