23、Introduction p Add: An investigation by CENELEC TC 61 has shown that all risks from products within the scope of this standard are fully covered by the Low Voltage Directive, 73/23/EEC. For products having mechanical moving parts, a risk assessment in accordance with the Machinery Directive, 98/37/E
24、C, has shown that the risks are mainly of electrical origin and consequently this directive is not applicable. However, the relevant essential safety requirements of the Machinery Directive are covered by this standard together with the principal objectives of the Low Voltage Directive. _ Endorsemen

30、xperienced 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 taking into account the manufacturers instructions. It also covers abnormal situation
31、s 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 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
32、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 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 standa
33、rd dealing with the safety of appliances and takes precedence over horizontal and generic standards covering the same subject. An appliance that complies with the text of this standard will not necessarily be considered to comply with the safety principles of the standard if, when examined and teste
34、d, it is found to have other features that impair the level of safety covered by these requirements. An appliance employing materials or having forms of construction differing from those detailed in the requirements of this standard may be examined and tested according to the intent of the requireme
35、nts and, if found to be substantially equivalent, may be considered to comply with the standard. 5egaP 3002:99253306NESBPage5 EN60335299:2003 HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES SAFETY Part 2-99: Particular requirements for commercial electric hoods 1 Scope This clause of Part 1 is replaced
36、by the following. This International Standard deals with the safety of electrically operated commercial hoods intended for installation above commercial cooking appliances such as ranges, griddles, griddle grills and deep fat fryers, and not intended for household use, their rated voltage being not
37、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 which when assembled form a complete working hood, incorporating a fan, are within the scope of the standard. NOTE 101 Hoods are
38、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 the same or different types. So far as is practicable, this standard deals with the common hazards presented by these types of appli
39、ances. 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 many countries additional requirements including ventilation requirements are specified by the national health authorities, the n
40、ational 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); purpose-built hoods, although this standard can be used as a guide (a purpose-built hood is either constructed on-site or specially c
41、onstructed 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 locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas). NOTE 104
42、 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 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 indi
43、vidual 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 rated power input. 6egaP 3002:99253306NESBPage6 EN60335299:2003 3.1.9 Replacement: normal operation operation of the appliance under t
44、he 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 collect contaminated air from above cooking ranges, hobs and similar cooking appliances. NOTE 1 The contamin
45、ated air may pass through a filter and be discharged back into the room or removed from the room. NOTE 2 The cooking appliances may be supplied by electricity or fuels such as gas. 4 General requirement This clause of Part 1 is applicable. 5 General conditions for the tests This clause of Part 1 is
46、applicable. 6 Classification This clause of Part 1 is applicable except as follows. 6.1 Replacement: Hoods shall be class I with respect to protection against electric shock. Compliance is checked by inspection and by the relevant tests. 7 Marking and instructions This clause of Part 1 is applicable
47、 except as follows. 7.1 Addition: Hoods shall be marked on or near the lampholder with the maximum power input of replaceable illumination lamps as follows: lamp max. W or max.W 7.6 Addition: Add the following symbol: symbol 5021 of IEC 60417-1 equipotentiality 7egaP 3002:99253306NESBPage7 EN6033529
48、9:2003 7.12 Addition: The instructions for use shall state the substance of the following: there shall be adequate air intake into the room when the hood is used at the same time as appliances burning gas or other fuels; the details concerning the method and frequency of cleaning and that filters mu
49、st be cleaned regularly; there is a fire risk if cleaning is not carried out in accordance with the instructions; do not flamb under the hood. If Symbol 5021 of IEC 60417-1 is marked on the hood, its meaning shall be explained. 7.12.1 Replacement: The hood shall be accompanied by instructions detailing any special precautions necessary for installation.
