ÖNORM EN 13079

Issue date: 2025 12 15

Devices to prevent pollution by backflow of potable water - Air gap with injector - Family A - Type D

This document specifies the characteristics and the requirements of air gap with injector Family A, Type D for nominal flow velocity not exceeding 3 m/s. Air gaps are devices for protection of potable water in water installations from pollution by backflow. This document is applicable to air gaps in factory-assembled products and to constructed air gaps in situ and specifies requirements and methods to verify and ensure compliance with this document during normal working use. The fluid in the receiving vessel is assumed to have similar properties to the water supply. Where this is not the case, additional care or tests can be required to verify the efficacy of the solution in practical use. The AD device is intended to be used in potable water installations according to EN 806 (all parts).

Frequently Asked Questions about ÖNORM EN 13079

What is a "Single-User Licence"?

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.
