DIN EN IEC 62471-6:2024-05

The scope of this document covers lamps and lamp products, including LED-based ones, whose main purpose is to emit radiant energy in the ultraviolet range, meaning that more than half of the total radiant power emitted in the wavelength range from 180 nm to 3,000 nm falls within the spectral range from 180 nm to 400 nm. This also includes medical diagnostic and cosmetic devices/products that emit primarily UV radiation. In addition to the evaluation distances and measurement conditions for various UV lamp products, this document describes a system for classifying ultraviolet lamp products into a risk group system and the resulting requirements for product labeling and user information regarding safety measures. Lamps and lamp products whose optical radiation power is predominantly outside the UV spectral range, which emit mainly in the visible and/or infrared spectral range, are not covered by the scope of this document. This includes lamps and lamp products used for general lighting and/or the emission of thermal radiation. Furthermore, fluorescent UV lamps intended for skin tanning and medical UV lamp products for medical treatment purposes are not covered by the scope of this document. The scope of this document does not cover non-optical hazards that may result from the use of UV lamp products, such as the formation of ozone or the release of mercury. This document applies to lamps and lamp products designed to emit radiant energy in the UV range. Products of this type have a wide range of applications. They are used, for example, in public facilities such as hospitals and swimming pools, or in the home as so-called germicidal lamps for disinfecting air, water, or objects. In the form of so-called light traps, they are used to combat night-flying insects. In the entertainment sector, UV lamps are used as “black light” to create optical effects in combination with fluorescent dyes. UV lamps are also used to cure inks, powder coatings, and other polymers such as adhesives, dental fillings, and (nail) polishes. In the scientific and medical fields, UV light sources have a wide range of applications in non-destructive analysis and diagnosis. Last but not least, UV lamps also play an important role in authenticity testing, for example to make seals and markings on official documents and banknotes visible. This document aims to make the use of UV lamp products as safe as possible by minimizing unnecessary emissions of UV radiation that would lead to unnecessary human exposure.
