Over the years, the quality and safety of indoor tanning devices - without which a tanning facility cannot operate - have improved substantially. This is especially the case since the publication of EN 60335-2-27, which limits the erythemal irradiance to 0,3 W/m2. On the other hand, safe use of commercially offered indoor tanning devices is critically dependent on the way the service is provided. Particularly important is the way in which potential customers are informed about the proper use of tanning devices taking into account the personal characteristics of the consumer. Together with Part 2, this part of EN 16489 contributes to further strengthening consumer information, protection and safety with regard to commercially offered indoor tanning services by defining the requirements for training courses for indoor UV exposure consultants.
