IEC 60335-2-27:2009 deals with the safety of electrical appliances incorporating emitters for exposing the skin to ultraviolet or infrared radiation, for household and similar use, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. Appliances intended to be used in tanning salons, beauty parlours and similar premises, are also within the scope of this standard. The principal changes in this edition as compared with the fourth editio of IEC 60335-2-27 are as follows:
- clarification of radiation measurement procedure (32.101);
- guidelines for exposure time schedule (Annex DD).
The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with 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 60335-1:2013.
