scope:

This Standard covers UV microbiological water treatment systems and components for point-of-use (POU) and point-of-entry (POE) applications. Systems are intended to be used under the following specific conditions.

Purpose

The purpose of this Standard is to establish minimum requirements for the reduction of microorganisms using ultraviolet (UV) radiation. UV water treatment systems covered by this Standard are intended for water that may be either microbiologically safe or microbiologically unsafe. This Standard also specifies the minimum product literature and labeling information that a manufacturer shall supply to authorized representatives and system owners, as well as the minimum service-related obligations that the manufacturer shall extend to system owners.
