家用及类似用途电器 安全 第2-12部分：加热板和类似用途器具的特殊要求

[中文适用范围]： 本部分IEC 60335涉及家用和类似用途的电动保温板、保温盘及类似器具的安全，其额定电压不超过250V，包括直流供电设备和电池供电设备。这些器具用于保持食物或容器温暖。 适用于正常家用和类似用途的器具，也可被非专业人士在商店、轻工业和农场使用。然而，如果器具旨在专业用于保持容器温暖或加工商业消费食品，则不被视为仅用于家用和类似用途。 本标准尽可能处理所有人在家中及周围遇到的常见危险。然而，通常不考虑以下情况： - 身体、感官或智力能力有限，或缺乏经验和知识，导致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。 注意： - 用于车辆、船舶或飞机的器具可能需要附加要求； - 在许多国家，国家卫生当局、劳动保护当局等可能规定了附加要求。 本标准不适用于： - 由柔性材料（如纺织材料）制成的器具； - 专用于特殊条件（如腐蚀性或爆炸性环境）的器具； - 专用于商业餐饮或工业用途的器具（IEC 60335-2-49、IEC 60335-2-50）； - 专用于工业用途的器具； - 保温柜。 [外文原描述]： IEC 60335-2-12:2024 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 60335-2-12:2024 edition 6.0 and the previous IEC 60335-2-12:2002+AMD1:2008+AMD2:2017 CSV edition 5.2. Furthermore, comments from IEC TC 61 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 60335-2-12:2024 deals with the safety of electric warming plates, warming trays and similar appliances intended to keep food or vessels warm, for household and similar purposes, their rated voltage being not more than 250 V including direct current (DC) supplied appliances and battery-operated appliances. Appliances intended for normal household and similar use and that can also be used by laypersons in shops, in light industry and on farms are within the scope of this standard. However, if the appliance is intended to be used professionally to keep vessels warm or to process food for commercial consumption, the appliance is not considered to be for household and similar use only. 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. Attention is drawn to the fact that – for appliances intended to be used in vehicles or on board ships or in 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 – appliances made of flexible material, such as textile material; – appliances intended exclusively to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas); – appliances intended exclusively for commercial catering (IEC 60335 2 49, IEC 60335 2 50); – appliances intended exclusively industrial purposes; – warming cabinets. This sixth edition cancels and replaces the fifth edition published in 2002, Amendment 1:2008 and Amendment 2:2017. 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, 5.2, 7.12, 15.2, 15.101, 24.1.5); c) application of test probe 19 (8.1.1, 20.2, B.22.3, B.22.4); d) clarification of applicability of requirements for remote operation (22.40, 22.49, 22.51). 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.
