IEC 60335-2-53:2011涉及额定功率输入不超过20千瓦的电桑拿加热设备和红外线发射装置的安全性，单相设备的额定电压不超过250伏，其他设备的额定电压不超过480伏。本标准涵盖的设备旨在用于家庭和位于公寓楼、酒店和类似场所的公共桑拿浴室。本标准还涉及配有加湿器的电桑拿加热设备的安全性，单相设备的额定电压不超过250 V，其他设备的额定电压不超过480 V。室内空气通过蒸发或雾化水来加湿。这第四版取消并取代了2002年出版的第三版及其修正案1（2007）。它构成技术修订。与IEC 60335-2-53第三版相比，该版本的主要变化如下: -范围改为覆盖红外舱； -增加了对嵌入式桑拿加热器的额外要求； -增加了电子联锁的要求（22.108）。 请各国家委员会注意，在新的、修订的或修订的IEC出版物出版后，设备组织可能需要一个过渡期，以便根据新的要求制造产品，并为进行新的或修订的测试做好准备。委员会建议，该出版物的内容应在出版之日起12个月或36个月内通过，以便在全国范围内实施。 本出版物应与IEC 60335-1:20 10一起阅读。

IEC 60335-2-53:2011 deals with the safety of electric sauna heating appliances and infrared emitting units having a rated power input not exceeding 20 kW, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. The appliances covered by this standard are intended for use in the home and in public saunas located in blocks of flats, hotels and similar locations. This standard also deals with the safety of electric sauna heating appliances provided with a humidifier unit, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. The room air is humidified by evaporating or atomising water. This fourth edition cancels and replaces the third edition published in 2002 and its Amendment 1 (2007). It constitutes a technical revision. The principal changes in this edition as compared with the third edition of IEC 60335-2-53 are as follows:
- the scope is changed to cover infrared cabins;
- additional requirements for recessed sauna heaters are added;
- requirements of electronic interlocks are added (22.108).
The attention of National Committees is drawn to the fact that equipment organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months or later than 36 months from the date of publication.

This publication is to be read in conjunction with IEC 60335-1:2010.
