IEC 60335-2-11:20 24 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 60335-2-11:20 24 EXV包括参考IEC 60335-1:20 20的内容。 IEC 60335-2-11:20 24涉及家用和类似用途的电动滚筒烘干机的安全性，单相电器的额定电压不超过250 V，其他电器（包括直流（DC）供电电器和电池供电电器）的额定电压不超过480 V。本标准适用于具有烘干循环的洗衣机的烘干功能。该标准还涉及热泵型滚筒干燥机的安全性。这些电器可能使用易燃制冷剂。这些设备的附加要求见标准附件AA。不用于正常家庭使用但可能对公众造成危险的电器，如用于商店、轻工业和农场的非专业人员使用的电器，属于本标准的范围。这种器具的例子是用于公寓或洗衣房中公共使用的滚筒式烘干机。在可行的情况下，本标准涉及所有人都会遇到的器具带来的常见危险。 然而，一般来说，它没有考虑到 -身体、感官或精神能力受损的人（包括儿童）；或缺乏经验和知识使他们无法在没有监督或指导的情况下安全使用器具；-儿童在玩电器。 提请注意以下事实: -对于拟用于车辆或船舶或飞机上的器具，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、国家供水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； -拟在有特殊条件的地方使用的器具，例如存在腐蚀性或爆炸性气氛（灰尘、蒸汽或气体）； -装有蒸汽发生装置的器具，其中蒸汽在超过50kPa的压力下产生。 本第九版取消并取代2019年出版的第八版。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)将一些说明转换为规范性文本（附件AA第1条）； c)对设备类型实施新的定义（3.5.102、3.5.103、3.5.104）； d)22.51中增加了远程操作的具体要求； e)在第24条中增加了电机运行电容器的具体要求； f)附件R的新修改； g)更新附件AA第21条和第22条中关于使用易燃制冷剂的器具的要求； 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 60335-2-11:2024 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 60335-2-11:2024 EXV includes the content of the references made to IEC 60335-1:2020.

IEC 60335-2-11:2024 deals with the safety of electric tumble dryers intended for household and similar purposes, 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 and battery-operated appliances. This standard applies to the drying function of washing machines having a drying cycle. This standard also deals with the safety of heat pump type tumble dryers. These appliances may use flammable refrigerants. Additional requirements for these appliances are given in normative Annex AA. 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 laymen in shops, in light industry and on farms are within the scope of this standard. Examples of such appliances are tumble dryers for communal use in blocks of flats or in launderettes. As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons.
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, the national water supply authorities.
This standard does not apply to
- appliances intended exclusively for industrial purposes;
- 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);
- appliances incorporating steam generating devices in which steam is produced at a pressure exceeding 50 kPa.
This ninth edition cancels and replaces the eighth edition published in 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, Annex AA);
c) implement new definitions to type of appliances (3.5.102, 3.5.103, 3.5.104);
d) specific requirements have been added in 22.51 for remote operation;
e) specific requirements have been added in Clause 24 for motor running capacitors;
f) new modifications in Annex R;
g) update of requirements for appliance that use flammable refrigerants in Clause 21 and Clause 22 of Annex AA;
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.
