Bibliography

This document specifies definitions, principles of construction, requirements and methods for testing the performance of UV devices for drinking water installations inside buildings which are permanently connected to the mains supply at the point of entry into a building or within the water distribution system inside the building.UV devices in the sense of this standard are UV bactericidal treatment devices or UV disinfection devices.
