家用和类似用途电器.安全.第2-64部分:商用厨房电动机器的特殊要求

[中文适用范围]： 本部分IEC 60335涉及电动商用厨房机器的安全，其额定电压不超过250V（单相设备连接在一相和中性线之间），其他设备包括直流供电设备和电池供电设备的额定电压不超过480V。这些设备不适用于家庭和类似用途。它们用于在不对公众开放的区域进行食品的商业加工，例如餐馆、食堂、医院的厨房以及面包店和肉店等商业企业。厨房机器的示例包括搅拌机、液体或食品搅拌器、揉面机、打蛋器、切碎机、磨碎机、绞肉机、切片机、削皮机、开罐器、咖啡研磨机、用于清洗和/或干燥食品的机器、分份机、面团辊压机、面条切割机、食品加工机和光束搅拌机。本标准也适用于为便于运输而分成多个部分（子组件）提供的设备，这些部分在安装地点组装后形成一个结构单元而无需使用任何附加零件。利用其他形式能源的设备的电气部分也在本标准的范围内。本标准尽可能处理这些类型设备所呈现的常见危险。注意：对于用于车辆、船舶或飞机上的设备，可能需要附加要求；在许多国家，国家卫生部门、国家劳动保护部门、国家供水部门和类似部门规定了附加要求。本标准不适用于专为工业用途设计的设备；用于存在特殊条件（如腐蚀性或爆炸性环境（粉尘、蒸汽或气体））的场所的设备；用于食品连续大规模生产的设备；独立的输送设备，如食品分配带。 [外文原描述]： IEC 60335-2-64:2021 deals with the safety of electrically operated commercial kitchen machines, 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 including direct current (DC) supplied appliances and battery operated 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. Examples of kitchen machines are – mixers; – liquid or food blenders; – kneaders; – beaters; – shredders; – graters; – mincers; – slicers; – peelers; – tin openers; – coffee grinders; – machines used for washing and/or drying food; – portioning machines; – pastry rollers; – noodle strip cutters; – food processors; – beam mixers. This standard also applies to appliances which, in order to facilitate transport, are supplied in several parts (sub-assemblies) which, when assembled at the place of installation, form a constructional unit without the use of any additional parts. 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 aircraft, 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. 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; – independent conveying equipment, such as food distribution belts. This fourth edition cancels and replaces the third edition published in 2002, Amendment 1: 2007 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 (1, 7.12, 9.101, 10.1, 11.7, 15.3, 20.2, 20.116, 20.117, 20.117.2, 20.117.3, 20.119, 22.101, 23.3, 27.2); c) clarifications to some test specifications have been made (9.101, 15.1.1, 15.2, 22.113); d) exclusion of appliances used in areas open to the public (Clause 1); e) clarification of requirements for battery-operated appliances (Clause 1, 11.7, B.3.1.1, B.11.1); f) relocation of cleaning instructions from 7.12.1 to 7.12; g) conciliation of the text of IEC 60335-2-64 with other standards under IEC/TC61/MT32. 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.
