(Main)Ventilation for buildings - Measurement of air flow rates on site - Methods
Ventilation for buildings - Measurement of air flow rates on site - Methods
This document specifies methods for the measurement of air flow rates on site. It provides a description of the air flow rate measurement methods and how measurements are performed within the margins of stipulated method uncertainties. It gives the necessary measurement conditions (e.g. length of straight duct, uniform velocity profile) to achieve the stipulated measurement uncertainties.
The methods for measuring the air flow rate inside ducts do not apply to:
- ducts that are not circular or rectangular (e.g. oblong ducts);
- flexible ducts.
Lüftung von Gebäuden - Luftvolumenstrommessung in Lüftungssystemen - Verfahren
Dieses Dokument legt Verfahren für die Messung von Luftvolumenströmen vor Ort fest. Es enthält eine Beschreibung der Verfahren für die Messung von Luftvolumenströmen und wie Messungen innerhalb der für das Verfahren vorgeschriebenen Toleranzen durchgeführt werden. Es enthält die notwendigen Messbedingungen (z. B. Länge der geraden Luftleitung, gleichmäßiges Geschwindigkeitsprofil) zur Erreichung der vorgegebenen Messunsicherheiten.
Die Verfahren zur Messung des Luftvolumenstroms in Luftleitungen sind nicht anwendbar für:
Luftleitungen, die nicht kreisförmig oder rechteckig sind (z B. längliche Luftleitungen);
flexible Luftleitungen.
Ventilation des bâtiments - Mesurages des débits d'air sur site - Méthodes
Le présent document spécifie des méthodes pour le mesurage des débits d’air sur site. Il fournit une description des méthodes de mesurage de débit d’air et indique la façon dont les mesurages sont réalisés dans les marges d’incertitude de la méthode stipulée. Il donne les conditions de mesure nécessaires (par exemple, longueur de conduit droit, profil de vitesse uniforme) pour atteindre les incertitudes de mesure stipulées.
Les méthodes de mesure du débit d’air dans les conduits ne s’appliquent pas:
- aux conduits qui ne sont pas circulaires ou rectangulaires (par exemple, conduits oblongs);
- aux conduits flexibles.

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 156.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.
This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.
