IEC 60335-2-69:2021涉及电动真空吸尘器的安全性，包括背负式真空吸尘器和吸尘器，用于湿吸、干吸或干湿两用，用于商业室内或室外，带或不带附件。这些机器可以设置有吹气或充气功能。灰尘容器连接件与吸入软管的内径不得超过200 mm。 它还涉及集中式真空吸尘器的安全性，不包括系统的安装。 需要注意的是，本标准没有涉及集中式真空吸尘器安全安装的附加要求，但需要考虑这些要求。 本标准适用于商用机器。以下列表虽然不全面，但给出了包含在范围内的位置的指示:-公共使用区域，如旅馆、学校、医院； -工业场所，例如工厂和制造车间； -零售店，例如商店和超市； -营业场所，例如办事处和银行； -除正常内务用途外的所有用途。 这些机器没有配备牵引传动装置。涵盖以下电力系统: -对于单相电器，额定电压高达250 V，对于其他电器，额定电压高达480 V的市电供电电机， -电池供电的电机。 IEC 60335-2-72涵盖了具有相同预期功能但配备牵引驱动的机器。 本标准也适用于处理危险粉尘（如石棉）和爆炸性粉尘环境以外的可燃粉尘的机器。 标准附件AA中给出了处理有害粉尘的机器的附加要求。提请注意，在许多国家，可能适用关于危险物质的额外要求。 就本标准而言，有害粉尘的定义不包括放射性物质。 本标准不适用于 -家用真空吸尘器和吸水清洁器具（IEC 60335-2-2）； -商用地板处理机（IEC 60335-2-67、IEC 60335-2-72）； -商用喷雾提取机(IEC 60335-2-68)； IEC 60335-2-67和IEC 60335-2-68仅涵盖无牵引驱动的机器。 -手持式电源操作的电动花园鼓风机、真空吸尘器和鼓风机真空吸尘器（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）； -医疗器械（IEC 60601-1); -设计用于腐蚀性环境的机器； -设计用于拾取闪点低于55°C的液体的机器； -设计用于爆炸性环境（粉尘、蒸汽或气体）的机器，但设计用于22区的机器除外； -用于从壁炉、烟囱、烤箱、烟灰缸和类似积灰场所吸灰的机器。 本第六版取消并取代2016年出版的第五版。它构成技术修订。 与上一版相比，此版本包括以下重大技术变更: -编辑和技术符合IEC 60335-1:20 20； -增加了在爆炸性粉尘环境以外的环境中拾取可燃粉尘的要求。 本第2部分仅与最新版本的IEC 60335-1及其修正案一起使用。它是在该标准第六版（2020年）的基础上建立的。

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.
