家用和类似用途电器的安全第2-99部分:商用电罩的特殊要求

[中文适用范围]： 本部分IEC 60335涉及电动商用抽油烟机的安全性，适用于安装在商用烹饪设备（如炉灶、平底煎锅、煎烤架和油炸锅）上方的电动商用抽油烟机，其额定电压不超过单相抽油烟机（连接在一相和中性线之间）的250V和其他抽油烟机的480V。仅包括单个完整单元和作为单独部件供应的抽油烟机，这些部件组装后形成一个完整的工作抽油烟机，包含风扇。 注101：抽油烟机用于例如餐厅、食堂、医院的厨房以及商业企业如面包店、肉店等。 抽油烟机可以用于一个或多个相同或不同类型的设备上方。 以下抽气系统适用于本标准： - 后抽式通风系统； - 下抽式通风系统； - 烟气抽气模块。 这些设备不适用于家庭和类似用途。它们用于不对公众开放的区域，例如餐厅、食堂、医院的厨房以及商业企业如面包店和肉店。 在可行的情况下，本标准处理这些类型设备带来的常见危险。 注102：请注意： - 对于用于车辆、船舶或飞机上的抽油烟机设备，可能需要额外的要求； - 在许多国家，国家卫生当局、负责劳动保护的国家当局和类似当局规定了包括通风要求在内的额外要求； - 对于包含电离空气过滤系统的抽油烟机，IEC 60335-2-65也适用。 注103：本标准不适用于： - 家用抽油烟机（IEC 60335-2-31）； - 定制抽油烟机，尽管本标准可以作为指南（定制抽油烟机是在现场建造或工厂特别建造的，不进行批量生产）； - 不包含风扇的抽油烟机设备； - 专为工业用途设计的抽油烟机设备； - 用于特殊条件（如腐蚀性或爆炸性环境（粉尘、蒸汽或气体）的抽油烟机设备； - 电池供电设备。 注104：关于外置风扇抽油烟机的要求正在考虑中。 [外文原描述]： IEC 60335-2-99:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60335-2-99:2021 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, their rated voltage being not 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. The hood may be used above one or more appliance or types of appliances. The following extraction systems are within the scope of this standard: - back-draft ventilation systems; - down-draft ventilation systems; - fume extraction modules. These appliances are not intended for household and similar purposes. They are used in areas not open to the public, for example in kitchens of restaurants, canteens, hospitals and in commercial enterprises such as bakeries and butcheries. 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 including ventilation requirements are specified by the national health authorities, the national authorities responsible for the protection of labour and similar authorities. 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 constructed in the factory and is not mass produced); - appliances not incorporating a fan; - 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); - battery-operated appliances. This second edition cancels and replaces the first edition published in 2003 and Amendment 1:2017. 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 (Clause 1, 11.7, 22.102, 22.104, 27.2, 30.101); c) exclusion of battery-operated appliances and appliances used in areas open to the public (Clause 1); d) addition of requirement for appliances incorporating means for ionizing air (32.101); e) conciliation of the text of IEC 60335-2-99 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.
