IEC 60335-2-61:2024 EXV包含国际标准及其扩展版本(EXV)。IEC官方标准的扩展版本仅提供英文版本，为用户提供了标准的全面内容。IEC 60335-2-61:2024 EXV包括参考IEC 60335-1:20 20的内容。 IEC 60335-2-61:2024涉及用于加热其所在房间的家用和类似用途的电蓄热房间加热器的安全性，其额定电压对于单相电器不超过250 V，对于其他电器（包括直流(DC)供电的电器）为480 V。不打算用于正常家庭使用但可能对公众造成危险的电器，如打算供非专业人员在商店、轻工业和农场使用的电器，属于本标准的范围。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: -本标准仅适用于独立式蓄热式房间加热器。然而，在合理适用的范围内，它可以用作确定其他蓄热房间加热器的要求和测试规范的指南； -对于包含直接作用加热元件的加热器，IEC 60335-2-30也适用； -对于打算用于车辆或船舶或飞机上的加热器，可能需要额外的要求； -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 -专供工业用途的器具； -结合在建筑结构中的加热器； -中央供暖系统； -桑拿浴用加热器(IEC 60335-2-53)； -用于房间加热的柔性片加热元件(IEC 60335-2-96)； -打算在有特殊条件的地方使用的加热器，例如存在腐蚀性或爆炸性气氛（灰尘、蒸汽或气体）。 本第三版取消并取代了2002年出版的第二版、修正案1:20 05和修正案2:20 08。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)删除一些注释或将其转换为规范性文本（第1、7条）。1,10.1,19.3.102,24.101); c)已经介绍了测试探针19的应用(8.1.1、20.2)； d)更新了温度限值并定义了测量要求（第11.3、11.8条，表101）； e)利用用于测量表面温度的探针实现图101。 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 60335-2-61:2024 EXV contains both the international standard and its extended version (EXV). This extended version of the official IEC Standard is available in English only and provides the user with a comprehensive content of the Standard. IEC 60335-2-61:2024 EXV includes the content of the references made to IEC 60335-1:2020.

IEC 60335-2-61:2024 deals with the safety of electric thermal-storage room heaters for household and similar purposes that are intended to heat the room in which they are located, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances including direct current (DC) supplied appliances. Appliances not intended for normal household use but which nevertheless can be a source of danger to the public, such as appliances intended to be used by laypersons in shops, in light industry and on farms, are within the scope of this standard. 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
- this standard only applies to self-contained thermal-storage room heaters. However, it can be used as a guide, in so far as it reasonably applies, to determine the requirements and test specifications for other thermal-storage room heaters;
- for heaters incorporating direct-acting heating elements, IEC 60335-2-30 is also applicable;
- for heaters 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
- appliances intended exclusively for industrial purposes;
- heaters incorporated in the building structure;
- central heating systems;
- heaters for saunas (IEC 60335-2-53);
- flexible sheet heating elements for room heating (IEC 60335-2-96);
- heaters intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas).
This third edition cancels and replaces the second edition published in 2002, Amendment 1:2005 and Amendment 2:2008. 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) deletion or conversion of some notes to normative text (Clause 1, 7.1, 10.1, 19.3.102, 24.101);
c) application of test probe 19 has been introduced (8.1.1, 20.2);
d) temperature limits have been updated and requirements for measurement were defined (Clause 11.3, 11.8, Table 101);
e) implementation of Figure 101 with the probe for measuring surface temperatures.
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.
