27、al consensus of opinion on the subjects dealt with. 2) They have the form of recommendations for international use and they are accepted by the National Committees in that sense. 3) In order to promote international unification, the IEC expresses the wish that all National Committees should adopt th

28、e text of the IEC recommendation for their national rules in so far as national conditions will permit. Any divergence between the IEC recommendation and the corresponding national rules should, as far as possible, be clearly indicated in the latter. Foreword to Amendment A1 The proposal to endorse

41、ds: The electrical part of appliances making use of other forms of energy is also within the scope of this standard and the influence of the non-electrical parts on the electrical parts is taken into consideration. This standard does not apply to: steam cookers for industrial purposes; continuous pr

42、ocess steam cookers for the mass production of food; steam cookers with electrode heaters; appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas). For appliances intended to be used in vehicles o

43、r on board ships or aircraft, additional requirements may be necessary. Attention is drawn to the fact that in many countries additional requirements are specified by the national authorities responsible for health, for water supplies and for the protection of labour. In many countries additional re

44、quirements for pressure appliances are specified. These appliances are intended for use in professional kitchens, such as those in restaurants and hospitals, and in enterprises such as bakeries and butcheries. For appliances intended to be used in tropical countries, special requirements may be nece

46、sed in determining the rated input. 2.2.19 Addition: Wherever Class II is used in this standard it is understood to mean a part of Class II construction. 2.2.20 Addition: Wherever Class III is used in this standard it is understood to mean a part of Class III construction. 2.2.29 Replacement: Condit

47、ions of adequate heat discharge denote: that the appliance is operated in accordance with the manufacturers instructions with all controls intended to be operated by the user adjusted to their maximum setting until reaching operating temperature. Then they are readjusted, if possible, to the lowest

48、setting that maintains that temperature; that appliances with steam generators intended to be filled by hand are filled to the indicated level on the steam generator; that appliances with steam generators intended to be filled automatically are connected to a supply having the pressure designated by

49、 the manufacturer for correct operation. Where the manufacturer specifies a range of pressures, the pressure is adjusted to give the most unfavourable conditions; that the incoming water is maintained at: 15 5 C in the case of appliances intended for connection to a cold water supply; 60 5 C or the temperature indicated in the instruction sheet, whichever is the higher, in the case of appliances intended for connection to a hot water supply only. If the appliance is intended for connection to either a
