家用和类似用途电器 安全 第 2-72 部分：商业用途带或不带牵引驱动的地板处理机的特殊要求

[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动力骑乘式和动力步行式机器的安全性，适用于以下应用： – 清扫， – 擦洗， – 湿或干吸尘， – 抛光， – 应用蜡、密封产品和粉末洗涤剂， – 洗发地板。 这些机器的清洁运动更线性而非横向或周期性。 注101 相比之下，IEC 60335-2-67涵盖的机器的清洁运动更横向或周期性而非线性。 注102 本标准适用于商业用途的机器。以下列表虽不全面，但给出了范围内的位置示例： – 公共使用区域，如酒店、学校、医院； – 工业场所，如工厂和制造车间； – 零售店，如商店和超市； – 商业场所，如办公室和银行； – 所有非正常家务用途。 这些机器可能配备牵引驱动系统。涵盖以下动力系统： – 内燃机， – 额定电压不超过250V的单相电器和480V的其他电器的主电源电动机， – 电池驱动机器。 电池驱动机器可能配备内置电池充电器。 本标准不适用于： – 家用地板处理电器（IEC 60335-2-10）； – 商业用途的地板处理机器（IEC 60335-2-67）； – 商业用途的喷雾提取机器（IEC 60335-2-68）； – 商业用途的湿式和干式真空吸尘器，包括动力刷（IEC 60335-2-69）； – 道路清扫机； – 设计用于坡度超过20%的机器； – 配备动力输出（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； – 设计用于收集危险粉尘（如IEC 60335-2-69所定义）、易燃物质或炽热颗粒的机器； – 设计用于车辆、船上或飞机上的机器。 [外文原描述]： 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.
