IEC 603352-120:2024涉及产生可直接吸入气溶胶的设备的安全性，单相设备的额定电压不超过250 V，其他设备包括直流(DC)供电设备和电池供电设备。 本标准范围内的设备示例包括: -蒸汽和气雾剂设备； -含或不含尼古丁的个人电子烟器具； -电子烟； -电子尼古丁递送系统(ENDS)； -电子非尼古丁递送系统(ENNDS)； -用于加热烟草产品的电子烟草加热器具。 本标准不适用于: -医用呼吸机， -加湿器（IEC 60335-2-98）。 这些要求不包括消耗品，如电子液体和其他吸入的气溶胶物质、灯芯和使用过程中吸入的其他颗粒物，也不包括电器运行排放物中的物质。例如，气溶胶中的重金属排放和环境暴露不在本标准范围内。这些要求没有考虑与器具一起使用的任何消耗品的生理效应。本国际标准不涵盖受相关司法管辖区法律严格监管的含尼古丁或消耗尼古丁的产品的标签、包装和内容的要求或禁令。

IEC 603352-120:2024 deals with the safety of appliances for generation of directly inhalable aerosols, their rated voltage being not more than 250 V for single-phase appliances, and other appliances including direct current (DC) supplied appliances and battery-operated appliances.
Examples of the appliances that are within the scope of this standard are:
- vapour and aerosol appliances;
- personal vaping appliances with or without nicotine;
- electronic cigarettes;
- electronic nicotine delivery systems (ENDS);
- electronic non-nicotine delivery systems (ENNDS);
- electronic tobacco heating appliances for heated tobacco products.
This standard does not apply to:
- medical ventilators,
- humidifiers (IEC 60335-2-98).
These requirements do not cover the consumables, such as e-liquids and other inhaled aerosol substances, wicks, and other particulate matter inhaled during use, nor do they cover substances in the emissions from the operation of the appliances. For example, heavy metal emissions in the aerosol and environmental exposure are not covered by this standard. These requirements do not consider the physiological effects of any consumable used with the appliances. This International Standard does not cover requirements or prohibitions of the labelling, packaging and contents of nicotine-containing or nicotine-consuming products that are strictly regulated by law of the relevant jurisdiction.
