31、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, fire and radiation of appliances when operated as in normal use taking into

32、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 with the wiring rules when the appliance is connected to the supply mains. How

33、ever, 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 separately, as far as is reasonable. If applicable, the influence of one function on

34、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 complies with the text of this standard will not necessarily be considered to comp

35、ly 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 of construction differing from those detailed in the requirements of this sta

36、ndard 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.

This International Standard deal

38、s with the safety of electrically operated commercial grillers and toasters not intended for household use, their rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral, and 480 V for other appliances. Rotary or continuous grillers and toasters an

39、d similar appliances intended for grilling by radiant heat such as rotisseries, salamanders, etc. are within the scope of this standard. NOTE 101 These appliances are used, for example in restaurants, canteens, hospitals and commercial enterprises such as bakeries, butcheries, etc. The electrical pa

40、rt of appliances making use of other forms of energy is also within the scope of this standard. As 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 appliances intended to be used in vehicles or

41、 on board ships or aircraft, additional requirements may be necessary; in many countries additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities; for app

42、liances intended to be used outdoors, additional requirements may be necessary. NOTE 103 This standard 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 a corrosive or explo

43、sive atmosphere (dust, vapour or gas); continuous process appliances for the mass production of food; griddles and griddle grills (IEC 60335-2-38). 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 10

44、1 The rated power input is the sum of the power inputs of all the individual elements in the appliance that can be on at one time; where there are several such combinations possible, that giving the highest power input is used in determining the rated power input.

46、 with any controls intended to be operated by the user set at the maximum. Timers, if provided, are rendered inoperative. If doors, lids, reflectors or drip trays are provided, they are arranged in accordance with the manufacturers instructions. If no instructions are given, doors are fully open, dr

If the appliance cannot be operated without a load, then the manufacturers instructions are taken into account. Motors incorporated in the appliance are operated in the intended manner under the most severe co
