家用和类似用途电器. 安全. 第2-69部分: 商业用包括电动刷的湿及干型真空吸尘器的特殊要求

[中文适用范围]： 本部分IEC 60335涉及用于商业室内或室外使用的电动吸尘吸尘器（包括背负式吸尘器）和集尘器的安全，适用于湿吸、干吸或干湿两用，可带或不带附件。这些机器可提供吹气或充气功能。粉尘容器连接器到吸气管的内径不得超过200毫米。它还涉及中央吸尘系统的安全（排除系统的安装）。 注意101：请注意，本标准未涉及中央吸尘系统安全安装的额外要求，但在实施时必须予以考虑。 注意102：本标准适用于商业用途的机器。综合列表虽不完整，但给出了涵盖地点的指示：公共使用区域（如酒店、学校、医院）；工业场所（如工厂、生产车间）；零售场所（如商店、超市）；商业场所（如办公室、银行）；除正常家务用途外的所有用途。 这些机器不配备牵引驱动装置。涵盖以下电源系统：额定电压250V及以下的单相电源供电电机和480V及以下的其他电源供电电机；电池供电电机。 注意103：具有牵引驱动装置但功能相同的机器由IEC 60335-2-72涵盖。 本标准还适用于处理危险粉尘（如石棉）和可燃粉尘（非爆炸性粉尘环境）的机器。 注意104：处理危险粉尘的机器的额外要求见规范性附录AA。请注意，在许多国家，可能适用有关危险物质的额外要求。 注意105：放射性物质不在本标准对危险粉尘的定义范围内。 本标准不适用于：家用真空吸尘器（IEC 60335-2-2）；商业用地面处理机器（IEC 60335-2-67，IEC 60335-2-72）；商业用喷雾抽吸机器（IEC 60335-2-68）；家用喷水清洁器具；手持式 mains 供电花园吹风机、吸尘器和吹吸两用吸尘器（IEC 60335-2-100）；手持式和便携式电动工具（IEC 60745系列，IEC 61029系列，IEC 62841系列）；医疗用途器具（IEC 60601-1）；设计用于腐蚀环境的机器；设计用于吸取闪点低于55°C的液体的机器；设计用于爆炸环境（粉尘、蒸汽或气体，但设计用于22区除外）的机器；设计用于从壁炉、烟囱、烤箱、烟灰缸和类似积灰处吸取灰烬的机器。 [外文原描述]： IEC 60335-2-69:2021 deals with the safety of electrical motor-operated vacuum cleaners, including back-pack vacuum cleaners, and dust extractors, for wet suction, dry suction, or wet and dry suction, intended for commercial indoor or outdoor use with or without attachments. These machines may be provided with a blowing or inflating function. The inner diameter of the dust container connector to the suction hose shall not exceed 200 mm. It also deals with the safety of centrally-sited vacuum cleaners, excluding the installation of the system. Attention is drawn to the fact that additional requirements on the safe installation of centrally-sited vacuum cleaners are not addressed by this standard but need to be taken into account. This standard applies to machines for commercial use. The following list, although not comprehensive, gives an indication of locations that are included in the scope: – public use areas such as hotels, schools, hospitals; – industrial locations, for example factories and manufacturing shops; – retail outlets, for example shops and supermarkets; – business premises, for example offices and banks; – all uses other than normal housekeeping purposes. These machines are not equipped with a traction drive. The following power systems are covered: – mains powered motors up to a rated voltage of 250 V for single-phase appliances and 480 V for other appliances, – battery-operated motors. Machines for the same intended function but equipped with a traction drive are covered by IEC 60335-2-72. This standard also applies to machines handling hazardous dust, such as asbestos, and combustible dust in other than an explosive dust atmosphere. Additional requirements for machines handling hazardous dust are given in normative Annex AA. Attention is drawn to the fact that in many countries additional requirements on hazardous substances might apply. Radioactive substances are not covered by definition of hazardous dust for the purposes of this standard. This standard does not apply to – vacuum cleaners and water-suction cleaning appliances for household use (IEC 60335-2-2); – floor treatment machines for commercial use (IEC 60335-2-67, IEC 60335-2-72); – spray extraction machines for commercial use (IEC 60335-2-68); IEC 60335-2-67 and IEC 60335-2-68 cover only machines without traction drive. – hand-held mains-operated electrical garden blowers, vacuums and blower vacuums (IEC 60335-2-100); – hand-held and transportable motor-operated electric tools (IEC 60745 series, IEC 61029 series, IEC 62841 series); – appliances for medical purposes (IEC 60601-1); – machines designed for use in corrosive environments; – machines designed for picking up liquids with a flash point below 55 °C; – machines designed for use in explosive environments (dust, vapour or gas), except those designed for use in zone 22; – machines intended to vacuum ash from fireplaces, chimneys, ovens, ashtrays and similar places of ash accumulation. This sixth edition cancels and replaces the fifth edition published in 2016. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: – editorial and technical alignment with IEC 60335-1:2020; – addition of requirements for pick-up of combustible dusts in other than an explosive dust atmosphere. This part 2 is only to be used in conjunction with the latest edition of IEC 60335-1 and its amendments. It was established on the basis of the sixth edition (2020) of that standard.
