IEC 60335-2-4:20 23作为IEC 60335-2-4:20 23 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60335-2-4:2023涉及以下方面的安全性:-独立的电动旋转提取器，以及-结合在洗衣机中的旋转提取器，其具有用于洗涤和旋转提取的单独容器用于家用和类似用途，容量不超过10千克干布，滚筒圆周速度不超过50米/秒，其额定电压对于单相电器不超过250伏，对于包括直流（DC）供电电器和电池供电电器在内的其他电器不超过480伏。非供一般家庭使用但仍可能对公众构成危险的器具，例如供门外汉在商店、轻工业和农场使用的旋转式抽油烟机，以及供公寓或公共使用的旋转式抽油烟机在洗衣店，都在本标准的范围内。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合理可预见的危害。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、负责劳动保护的国家当局、国家供水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；-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环境（灰尘、蒸汽或气体）。这第八版取消并取代了2021年出版的第七版。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(20.103、20.104、22.101)；c)增加测试探针19，用于活动部件和活动部件的可接近性(8.1.1、20.2)；d)增加可接近的表面温度限制(11.3、11.8)；e)电池供电电器的规定操作条件(B.11.1).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 60335-2-4:2023 is available as IEC 60335-2-4:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60335-2-4:2023 deals with the safety of:
- stand-alone electric spin extractors, and
- spin extractors incorporated in washing machines that have separate containers for washing and spin extraction
for household and similar purposes that have a capacity not exceeding 10 kg of dry cloth and a drum peripheral speed not exceeding 50 m/s, their rated voltages 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.
Appliances not intended for normal household use but which nevertheless can be a source of danger to the public, such as spin extractors intended to be used by laymen in shops, in light industry and on farms and spin extractors for communal use in blocks of flats or in launderettes, are within the scope of this standard.
As far as is practicable, this standard deals with the reasonably foreseeable 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 and similar 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).
This eighth edition cancels and replaces the seventh edition published in 2021. 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 (20.103, 20.104, 22.101);
c) addition of test probe 19 for accessibility of live parts and moving parts (8.1.1, 20.2);
d) addition of accessible surface temperature limits (11.3, 11.8);
e) specified operating conditions for battery operated appliances (B.11.1).
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.
