IEC 60335-2-53 Ed. 4.1 b:2017

IEC 60335-2-53:2011+A1:2017 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. This consolidated version consists of the fourth edition (2011) and its amendment 1 (2017). Therefore, no need to order amendment in addition to this publication.
