IEC 61228-2020 Fluorescent ultraviolet lamps used for tanning – Measurement and specification method.
This document describes the method of measuring, evaluating and specifying the UV irradiation characteristics of fluorescent ultraviolet lamps that are used in appliances for tanning purposes.
It includes specific requirements regarding the marking of such lamps.
These requirements relate only to type testing.
Lamps complying with the requirements of this document comply with the electrical and mechanical safety requirements of IEC 61195 and IEC 61199 with the exception of the requirements for maximum limits of UV radiation.

3.1 ultraviolet lamp
lamp which radiates especially strongly in the ultraviolet, the visible radiation produced, if any, not being of direct interest
[SOURCE: IEC 60050-845:1987, 845-07-52, modified – Note deleted.]
3.2 fluorescent lamp
discharge lamp of the low-pressure mercury type in which most of the light is emitted by one or several layers of phosphors excited by the ultraviolet radiation from the discharge
[SOURCE: IEC 60050-845: 1987, 845-07-26, modified – Note deleted.]
3.3 spectroradiometer
instrument for measuring radiometric quantities in narrow wavelength intervals over a given spectral region
