Publication date:   Oct 21, 2005

Scope

This European Standard specifies the characteristics and the requirements of air gaps with circular overflow (restricted) family A, type F for nominal flow velocity not exceeding 3 m/s. Air gaps are devices for protection of potable water in water installations from pollution. This document applies to air gaps in factory assembled products and to constructed air gaps in situ, and defines the physicochemical characteristics of materials of construction used for the purpose and application to ensure compliance with this document during normal working use.
