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

This European Standard 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 European Standard are:
a)   leakage past a closed damper or valve (for classification see Annex C);
b)   casing leakage (for classification see Annex C);
c)   flow rate/pressure requirement characteristics;
d)   torque: (see Annex A);
e)   thermal transmittance: (see Annex B).
The acoustic testing of dampers and valves is not included in this European Standard.
The tests specified above apply to the following:
f)   measurement of leakage past a closed damper or valve;
g)   measurement of casing leakage;
h)   determination of flow rate and pressure requirements;
i)   measurement of torque characteristics (see Annex A);
j)   measurement of thermal transfer characteristics to determine insulation properties (see Annex B).
NOTE   Certain aspects of the dynamic performance of dampers or valves are dependent upon the air distribution system to which they are connected and are, therefore, difficult to measure in isolation. Such considerations have led to the omission of these aspects of the dynamic performance measurements from this European Standard. Also, in common with other air distribution components, the results from tests carried out in accordance with this European Standard may not be directly applicable if the damper or valve is situated in an area of non-uniform flow.

Lüftung von Gebäuden - Geräte des Luftverteilungssystems - Aerodynamische Prüfungen von Drossel- und Absperrelementen

Diese Europäische Norm legt Verfahren zur Prüfung und Bewertung von Drossel- und Absperrelementen fest, die in Luftverteilungssystemen mit Differenzdrücken bis zu 2 000 Pa verwendet werden.
Die vorliegende Europäische Norm umfasst die folgenden Prüfungen:
a) Leckage bei einem geschlossenen Drossel- bzw. Absperrelement (Klassifizierung siehe Anhang C);
b) Gehäuseleckage (Klassifizierung siehe Anhang C);
c) Typische Anforderungen an Volumenstrom/Druck;
d) Drehmoment (siehe Anhang A);
e) Wärmedurchgang (siehe Anhang B).
Die akustische Prüfung von Drossel- und Absperrelementen ist nicht in dieser Norm enthalten.
Die vorstehend festgelegten Prüfungen gelten für Folgendes:
f) Messung der Leckage bei einem geschlossenen Drossel- bzw. Absperrelement;
g) Messung der Gehäuseleckage;
h) Bestimmung der Anforderungen an Volumenstrom und Druck;
i) Messung des Drehmomentverlaufs (siehe Anhang A);
j) Messung der Wärmeübertragung zur Bestimmung der Wärmedämmungseigenschaften (siehe Anhang B).
ANMERKUNG Bestimmte Aspekte der dynamischen Leistung von Drossel- bzw. Absperrelementen sind abhängig vom Luftverteilungssystem, in das sie eingebunden sind, weshalb es schwierig ist, sie getrennt zu messen. Solche Erwägungen haben dazu geführt, dass diese Aspekte der Messung der dynamischen Leistung nicht in die vorliegende Europäische Norm aufgenommen wurden. Wie auch bei anderen Luftverteilungskomponenten sind die Ergebnisse von Prüfungen nach dieser Europäischen Norm möglicherweise nicht direkt anwendbar, wenn das Drossel- bzw. Absperrelement in einem Bereich ungleichmäßiger Strömung angeordnet ist.

Ventilation des bâtiments - Bouches d'air - Essais aérodynamiques des registres et clapets

La présente Norme européenne spécifie les méthodes d'essai et la classification des registres et des clapets utilisés dans les systèmes de distribution d'air avec des différences de pressions jusqu'à 2 000 Pa.
Les essais faisant partie de la présente Norme européenne sont :
a)   fuite à travers un registre ou un clapet fermé (pour la classification voir Annexe C) ;
b)   étanchéité de l'enveloppe (pour la classification voir Annexe C) ;
c)   caractéristiques des prescriptions débit/pression ;
d)   couple (voir Annexe A) ;
e)   transmission thermique (voir Annexe B).
Les essais acoustiques des registres et des clapets ne font pas partie de la présente Norme européenne.
Les essais cités ci-dessus s'appliquent pour :
f)   le mesurage d'une fuite à travers un registre ou un clapet fermé ;
g)   le mesurage de l'étanchéité de l'enveloppe ;
h)   la détermination des prescriptions de débit et de pression ;
i)   le mesurage des caractéristiques de couple (voir Annexe A) ;
j)   le mesurage des caractéristiques de transfert thermique afin de déterminer les propriétés d'isolation (voir Annexe B).
NOTE   Certains aspects des performances dynamiques des registres ou clapets sont dépendants du système de distribution d'air auquel ils sont raccordés et sont, par conséquent, difficiles à mesurer isolément. De telles considérations ont amené à omettre de la présente Norme européenne ces aspects de mesurage de la performance dynamique. De plus, comme pour d'autres composants de distribution d'air, les résultats d'essai effectués conformément à la présente Norme européenne peuvent ne pas être directement applicables si le registre ou le clapet est placé dans une zone d'écoulement non uniforme.

Prezračevanje stavb - Naprave za dovod in odvod zraka - Aerodinamično preskušanje dušilnikov in loput

Standard EN 1751 določa metode za preskušanje in ocenjevanje dušilnikov in loput, ki se uporabljajo v sistemih za dovod zraka z razlikami v tlaku do 2000 Pa. Preskusi, vključeni v ta evropski standard, so: a) puščanje skozi zaprt dušilnik ali loputo (glej Dodatek C za klasifikacijo); b) puščanje ohišja (glej Dodatek C za klasifikacijo); c) stopnja pretoka/zahteve glede tlaka; d) navor: (glej Dodatek A); e) toplotna prehodnost: (glej dodatek B). Akustični preizkusi dušilnikov in loput niso zajeti v tem standardu. Zgoraj navedeni preizkusi veljajo za naslednje: a) merjenje puščanja skozi zaprt dušilnik ali loputo; b) merjenje puščanja ohišja; c) določevanje stopnje pretoka in zahtev glede tlaka; d) merjenje navora (glej Dodatek A); e) merjenje toplotne prehodnosti za določevanje izolacijskih lastnosti (glej Dodatek B).
