Ventilation for buildings - Measurement of air flows on site - Methods

This European Standard specifies simplified methods for the measurement of air flows on site. It provides a description of the air flow methods and how measurements are performed within the margins of stipulated method uncertainties.
One measurement method is to take point velocity measurements across a cross-section of a duct to obtain the air flow. This simplified method is an alternative to the method described in ISO 3966 and EN 12599. This European Standard requests certain measurement conditions (length of straight duct and uniform velocity profile) to be met to achieve the stipulated measurement uncertainties for the simplified method.

Lüftung von Gebäuden - Luftvolumenstrommessung in Lüftungssystemen - Verfahren

Diese Norm gilt für die Messung von Luftvolumenströmen in Lüftungssystemen. Sie legt eine Beschreibung der Verfahren für Luftvolumenströme dar und wie Messungen innerhalb der für das Verfahren vorgeschriebenen Toleranzen durchgeführt werden.
Ein Messverfahren beruht auf der Messung von Punktgeschwindigkeiten über einen Querschnitt einer Luftleitung, um die Luftvolumenströmung zu bestimmen. Dieses vereinfachte Verfahren ist eine Alternative zu demn in ISO 3966 und EN 12599 beschriebenen Verfahren. Diese Norm setzt bestimmte Messumgebungen voraus (Länge gerader Luftleitungen und einheitliches Geschwindigkeitsprofil), die eingehalten werden müssen, um die vorgeschriebenen Toleranzen des vereinfachten Verfahrens zu erreichen.

Systèmes de ventilation pour les bâtiments - Mesurages de débit d'air dans les systèmes de ventilation - Méthodes

La présente Norme européenne spécifie des méthodes simplifiées pour le mesurage des débits d’air sur site. Elle fournit une description des méthodes de débit d’air et indique la façon dont les mesurages sont réalisés dans les marges d'incertitude de la méthode stipulée.
Une méthode de mesurage consiste en la prise de mesurages de la vitesse des points sur une section transversale d’un conduit afin d’obtenir le débit d’air. Cette méthode simplifiée est une variante de la méthode décrite dans l’ISO 3966 et l’EN 12599. La présente Norme européenne nécessite que certaines conditions de mesure (longueur de conduit droit et profil de vitesse uniforme) soient satisfaites afin d’obtenir les incertitudes de mesure spécifiées pour la méthode simplifiée.

Prezračevanje stavb - Meritve pretoka zraka v sistemu prezračevanja - Metode

Ta evropski standard določa poenostavljene metode za meritve pretoka zraka v sistemu prezračevanja. Podaja opis načinov pretoka zraka in kako se izvajajo meritve znotraj mejnih vrednosti negotovosti predpisane metode.
Pri eni merilni metodi je treba za izračun pretoka zraka meritve hitrosti točke prenesti prek preseka cevi. Ta poenostavljena metoda je alternativa metodi, opisani v standardih ISO 3966 in EN 12599. Ta evropski standard zahteva, da so izpolnjeni nekateri merilni pogoji (dolžina ravne cevi in enoten hitrostni profil), da je mogoče doseči predpisane merilne negotovosti za poenostavljeno metodo.
