家用和类似用途电器.安全.第2-54部分:家用液体或蒸汽表面清洁器具的特殊要求

[中文适用范围]： 本部分IEC 60335涉及家用电动清洁器具的安全，这些器具用于使用液体清洁剂或蒸汽清洁表面，其额定电压不超过250V，包括直流供电设备和电池供电设备。它还涵盖壁纸剥离器和表面清洁器具，这些器具包含加热元件或用于加压液体容器的手段。 本标准的适用范围尽可能涵盖所有家庭及其周围环境中人员所遇到的常见危险。然而，一般而言，本标准不考虑以下情况： - 那些由于身体、感官或智力能力不足，或缺乏经验和知识而无法在没有监督或指导的情况下安全使用器具的人员（包括儿童）； - 儿童玩耍器具的情况。 需要注意的是： - 对于打算在车辆、船舶或飞机上使用的器具，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额外的要求。 本标准不适用于： - 地板处理和湿式擦洗机（IEC 60335-2-10）； - 永久固定在建筑物上的清洁器具； - 由IEC 60335-2-79涵盖的清洁器具，即那些具有以下特点的器具： - 压力超过2.5 MPa； - 加压体积超过5升； - 压力（MPa）和容器体积（升）的乘积超过5； - 液体温度超过160°C； - 额定输入功率超过3500 W； - 用于商业或工业用途的清洁器具； - 打算在特殊条件下使用的器具，例如存在腐蚀性或爆炸性环境（灰尘、蒸汽或气体）； - 织物蒸汽机（IEC 60335-2-85）。 [外文原描述]： IEC 60335-2-54:2022 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 60335-2-54:2022 edition 5.0 and the previous IEC 60335-2-54:2008+AMD1:2015+AMD2:2019 CSV edition 4.2. Futhermore, comments from IEC TC 61 experts are provided to explain the reasons of the most relevant changes. IEC 60335-2-54:2022 deals with the safety of electric cleaning appliances for household use that are intended for cleaning surfaces by using liquid cleansing agents or steam, their rated voltage being not more than 250 V including direct current (DC) supplied appliances and battery-operated appliances. It also covers wallpaper strippers and surface cleaning appliances incorporating heating elements or means for pressurizing the liquid container. As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it does not take into account – persons (including children) whose physical, sensory or mental capabilities; or lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction; – children playing with the appliance. 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 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 – floor treatment and wet scrubbing machines (IEC 60335-2-10); – cleaning appliances that are permanently fixed to a building; – cleaning appliances covered by IEC 60335-2-79, namely those having a • pressure exceeding 2,5 MPa; • pressurised volume over 5 l; • product of pressure (in MPa) and container volume (in l) exceeding 5; • liquid temperature exceeding 160 °C; • rated power input exceeding 3 500 W; – cleaning appliances intended for commercial or industrial use; – 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); – fabric steamers (IEC 60335-2-85). This fifth edition cancels and replaces the fourth edition published in 2008, Amendment 1: 2015 and Amendment 2: 2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) alignment with IEC 60335-1:2020; b) conversion of some notes to normative text (Clause 1, 15.2, 21.103, 21.105, 22.103); c) addition of external accessible surface temperature limits (3.6.102, 3.6.103, 7.1, 11.3, 11.8) d) exception for hand-held appliances (20.1); 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.
