The safety advice in this document applies to UV-C sources and UV-C products which emit in the wavelength range of 1802 nm to 2803 nm.

Not within the scope are:

devices having their own product safety standard, such as IEC 60335-2-109 applicable to UV-C water disinfection equipment and IEC 60335-2-65 applicable to UV-C air disinfection equipment
application environments of UV-C devices
products combining UV-C irradiance with chemicals and additives
products that do not emit UV-C radiation such as UV-A, UV-B and near-UV devices
requirements for performance and functional characteristics
requirements for preventing material degradation and material damage
