ÖNORM EN 1751

Issue date: 2024 09 15

Ventilation for buildings - Air terminal devices - Aerodynamic testing of damper and valves

This document specifies methods for the testing and rating of dampers and valves used in air distribution systems with pressure differences up to 2 000 Pa. The tests incorporated in this document will address: - leakage past a closed damper or valve; - casing leakage; - flow rate/pressure requirement characteristics; - torque; - thermal transmittance. The tests specified above are applicable to the following: - measurement of leakage past a closed damper or valve; - measurement of casing leakage; - determination of flow rate and pressure requirements; - measurement of torque characteristics; - measurement of thermal transfer characteristics to determine insulation properties. This document does not apply to the acoustic testing of dampers and valves.

Frequently Asked Questions about ÖNORM EN 1751

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.

How can I get involved in the further development of this standard?

Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
