家用和类似用途电器.安全.第2-42部分:商用强制对流电烤箱、蒸汽炊具和蒸汽对流电烤箱的特殊要求

[中文适用范围]： 本部分IEC 60335处理了电动商用强制对流烤箱、蒸箱、蒸对流烤箱以及蒸汽发生器的安全性，其额定电压对于单相连接于一相与中性线之间的 appliance 不超过 250 V，对于其他 appliance 不超过 480 V。这些 appliance 不用于家庭及类似用途，而是用于商业食品加工，例如在餐馆、食堂、医院以及面包房和肉铺等商业企业中，且这些场所不对公众开放。本标准还涉及用于船舶的商用强制对流烤箱、蒸箱和蒸对流烤箱的安全性，附录 AA 适用于此类 appliance。使用其他形式能量的 appliance 的电气部分也在本标准的范围内。只要可行，本标准处理了这些类型 appliance 的共性危害。请注意：用于车辆、船舶或飞机上的 appliance 可能需要额外要求；在许多国家，国家卫生部门、国家劳工保护部门、国家供水部门以及类似部门规定了额外要求；在许多国家，对压力容器规定了额外要求。本标准不适用于：专门设计用于工业目的的 appliance；设计用于特殊环境（如存在腐蚀性或爆炸性气氛 - 粉尘、蒸气或气体）的 appliance；用于食品连续大规模生产的 appliance；微波炉（IEC 60335-2-90）；电池供电的 appliance。 [外文原描述]： IEC 60335-2-42:2021 deals with the safety of electrically operated commercial forced convection ovens, steam cookers, steam-convection ovens and, exclusive of any other use, steam generators, 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. These appliances are not intended for household and similar purposes. They are used for commercial processing of food in areas not open to the public, for example in kitchens of restaurants, canteens, hospitals and in commercial enterprises such as bakeries and butcheries. This standard deals also with electrically operated commercial forced convection ovens, steam cookers, steam-convection ovens intended for use on board ships, for which informative Annex AA is applicable. The electrical part 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. Attention is drawn to the fact that: - for appliances intended to be used in vehicles or on board ships or aircrafts, additional requirements can 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; - in many countries additional requirements are specified for pressure appliances. 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 explosive atmosphere (dust, vapour or gas); - appliances for continuous mass production of food; - microwave ovens (IEC 60335-2-90); - battery-operated appliances. This sixth edition cancels and replaces the fifth edition published in 2002, Amendment 1: 2008 and Amendment 2:2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the text has been aligned with IEC 60335-1:2020; b) some notes have been converted to normative text, modified or deleted (Clause 1, 7.15, 9.101, 10.1, 11.7, 19.2, 19.7, 20.101, 21.101, 22.101, 22.114, 27.2, 30.101); c) exclusion of battery-operated appliances and appliances used in areas open to the public (Clause 1); d) clarification of applicable standard for appliances for use by laymen (Clause 1, 7.12); e) relocation of cleaning instructions from 7.12.1 to 7.12; f) clarifications to some test specifications have been made (15.1.1, 15.2, 19.2, 19.7, 23.3, 25.3); g) introduction of a symbol to indicate risk of scalding (7.6); h) conciliation of the text of IEC 60335-2-42 with other standards under IEC TC 61/MT 32. This Part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments unless that edition precludes it; in that case, the latest edition that does not preclude it is used. It was established on the basis of the sixth edition (2020) of that standard.
