(Main)Ventilation for buildings - Measurement of air flows on site - methods
Ventilation for buildings - Measurement of air flows on site - methods
This standard applies to measurement of airflows on site. It provides the technician with a description of the methods,
their protocols, and tables for noting measured and calculated values so that the necessary measurements are
performed within the margins of stipulated method uncertainties.
Note : The duct traverse method in this standard is an alternative method to the duct traverse method of ISO 3966 and
EN12599. It defines errors due to the simplified approach and describes also other methods of measurements.
Lüftung von Gebäuden - Luftvolumenstrommessung in Lüftungssystemen - Verfahren
Diese Norm gilt für die Messung von Luftvolumenströmen in Lüftungssystemen. Sie bietet dem Techniker eine Beschreibung der Verfahren, deren Protokolle sowie Tabellen zum Protokollieren der gemessenen und berechneten Werte, so dass die erforderlichen Messungen innerhalb der für das Verfahren vorgeschriebenen Toleranzen durch¬geführt werden.
ANMERKUNG Das in dieser Norm verwendete Messverfahren über den Querschnitt der Luftleitung ist ein alternatives Verfahren zu dem Luftleitungsquerschnitts-Verfahren von ISO 3966 und EN 12599. Es werden Fehler infolge des vereinfachten Ansatzes definiert und außerdem weitere Messverfahren beschrieben.
Systèmes de ventilation pour les bâtiments - Mesurages de débit d'air dans les systèmes de ventilation - Méthodes
La présente norme s’applique à la mesure des écoulements d'air sur site. Elle fournit au technicien une description des méthodes, de leurs protocoles et des tableaux utilisés pour noter les valeurs mesurées et calculées, de sorte que les mesures nécessaires soient effectuées dans les marges d'incertitude de la méthode stipulée.
NOTE La méthode du plan transversal du conduit dans la présente norme est une variante de la même méthode décrite dans les normes ISO 3966 et EN 12599. Elle définit des erreurs dues à l'approche simplifiée et décrit également d'autres méthodes de mesure.

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.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland,
Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
