IEC 60335-2-72:2021作为IEC 60335-2-72:2021 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60335-2-72:2021涉及用于以下应用的商业室内或室外使用的电动乘坐式和电动手扶式机器的安全性: -清扫， -擦洗， -湿式或干式拾取， -抛光， -蜡、密封产品和粉末基洗涤剂的应用， -洗发 地板。 这些机器的清洁运动更线性，而不是横向或周期性。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。 这些机器可以配备牵引驱动系统。涵盖以下电力系统: -内燃机， -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， -电池驱动的机器。 电池操作的机器可以配备内置电池充电器。 本标准不适用于 -家用地板处理器具(IEC 60335-2-10)； -商用地板处理机（IEC 60335-2-67）； -商用喷雾提取机（IEC 60335-2-68); -用于商业用途的湿式和干式真空吸尘器，包括电动刷(IEC 60335-2-69)； -道路清扫机； -设计用于坡度超过20%的斜坡的机器； -配备动力输出装置(PTO)的机器； -设计用于腐蚀性或爆炸性环境（粉尘、蒸汽或气体）的机器； -设计用于拾取危险粉尘（定义见IEC 60335-2-69）、易燃物质或发光颗粒的机器； -设计用于车辆或船舶或飞机上的机器。 提请注意以下事实: -在许多国家，国家卫生主管部门、负责劳动保护的国家主管部门、国家供水主管部门和类似主管部门可规定有关安全使用所涉设备的额外要求；-为在公共道路上运输而设计的乘坐式机器可能会受到额外要求的约束（例如照明、牌照等）。 正在考虑对燃料电池的要求。这第五版取消并取代了2016年出版的第四版。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（未列出次要变更）: -编辑和技术符合IEC 60335-1:20 20； -将子条款重新排列为一致的编号22.101至22.113。 本第2部分应与最新版本的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 60335-2-72:2021 is available as IEC 60335-2-72:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60335-2-72:2021 deals with the safety of powered ride-on and powered walk-behind machines intended for commercial indoor or outdoor use for the following applications:
- sweeping,
- scrubbing,
- wet or dry pick-up,
- polishing,
- application of wax, sealing products and powder-based detergents,
- shampooing
of floors.
These machines have a cleaning motion which is more linear than lateral or periodic. 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 may be equipped with a traction drive system. The following power systems are covered:
- internal combustion engines,
- mains powered motors up to a rated voltage of 250 V for single-phase appliances and 480 V for other appliances,
- battery-operated machines.
Battery-operated machines may be equipped with a built-in battery charger.
This standard does not apply to
- floor treatment appliances for household use (IEC 60335-2-10);
- floor treatment machines for commercial use (IEC 60335-2-67);
- spray extraction machines for commercial use (IEC 60335-2-68);
- wet and dry vacuum cleaners, including power brush, for commercial use (IEC 60335-2-69);
- road sweepers;
- machines designed for use on slopes with a gradient exceeding 20 %;
- machines equipped with a power take-off (PTO);
- machines designed for use in corrosive or explosive environments (dust, vapour or gas);
- machines designed for picking up hazardous dusts (as defined in IEC 60335-2-69), inflammable substances, or glowing particles;
- machines designed for use in vehicles or on board of ships or aircraft.
Attention is drawn to the fact that
- in many countries additional requirements on the safe use of the equipment covered can be specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities;
- ride-on machines designed for transport over public roads can be subject to additional requirements (e.g. lighting, license plate etc.).
Requirements for fuel-cells are under consideration. This fifth edition cancels and replaces the fourth edition published in 2016. It constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition (minor changes are not listed):
- editorial and technical alignment with IEC 60335-1:2020;
- rearrangement of subclauses to consistent numbering 22.101 to 22.113.
This part 2 is 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.
