IEC 60335-2-12:20 24涉及家用和类似用途的用于保持食物或容器温暖的电加热板、加热托盘和类似器具的安全性，其额定电压不超过250 V，包括直流电(DC)供电的器具和电池供电的器具。 用于正常家庭和类似用途的电器，也可由商店、轻工业和农场的非专业人员使用，属于本标准的范围。然而，如果该器具旨在专业地用于保持容器温暖或加工用于商业消费的食品，则该器具不被视为仅用于家庭和类似用途。 在可行的情况下，本标准涉及家庭内外所有人都会遇到的电器带来的常见危险。提请注意以下事实: -对于拟用于车辆、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、负责保护劳工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 -由柔性材料如纺织材料制成的器具； -专门用于有特殊条件的场所的器具，如存在腐蚀性或爆炸性环境（灰尘、蒸汽或气体）； -专门用于商业餐饮的器具（IEC 60335 2 49、IEC 60335 2 50）； -专供工业用途的器具； -保温柜。 本第六版取消并取代2002年出版的第五版，修正案1:2008和修正案2:20 17。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更: a)符合IEC 60335-1:20 20； b)将一些注释转换为规范性文本（第1、5.2、7.12、15.2、15.101、24.1.5条）； c)测试探针19(8.1.1、20.2、B.22.3、B.22.4)的应用； d）澄清远程操作要求的适用性（22.40、22.49、22.51）。 本第2部分应与最新版本的IEC 60335-1及其修订一起使用，除非该版本排除了本第2部分；在这种情况下，使用不排除它的最新版本。它是在该标准第六版（2020年）的基础上建立的。

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.
