UV devices in the sense of this standard are UV bactericidal treatment devices or UV disinfection devices. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 1717, Protection against pollution of potable water in water installations and general requirements of devices to prevent pollution by backflow 3 Definitions For the purposes of this document, the following terms and definitions apply. 3.1 absorption decrease of the incident irradiance of a light beam including transformation into other forms suffered by radiant energy passing through a material substance (e. g. heat) 3.2 irradiance measure of the UV light flux divided by the area that intercepts the radiation, in W/m2
NOTE The irradiance measured in UV disinfection devices by the UV device sensor
is mainly influenced by the lamp output, the transmittance of the water, and scaling/fouling of the protective quartz sleeves and the position of the lamps in the radiation chamber. 3.3 disinfection action of killing or inactivating all types of pathogenic bacteria to a specified degree of at least 99,999 % and all types of pathogenic viruses to a degree of at least 99,99 % using a UV disinfection device 3.4 bactericidal treatment action of inactivating or killing bacteria present in water to an unspecified degree using a UV bactericidal treatment device 3.5 fluence dose product of irradiance in W/m2 and exposure time in s, in J/m2 NOTE Fluence is the correct term from a strictly scientific point of view.
3.6 germicidal fluence
fluence weighted with the germicidal UV sensitivity, in J/m2 SIST EN 14897:2006
