Curtain Walling - Watertightness - Laboratory test under dynamic condition of air pressure and water spray

This European Standard defines an additional test method which may be used when assessing the watertightness of curtain walling, both its fixed and openable parts. It is a supplementary test, not required for classification purposes, and it should be used only when the project specifier has determined its necessity.
It describes how the outside face of a curtain walling specimen should be subjected to a continuous spray of water and a turbulent airflow, with continuous pulses of positive air pressure on the outside of the test specimen generated from within the chamber.
This standard applies to any curtain walling product as defined in EN 13830.

Vorhangfassaden - Schlagregendichtheit - Laborprüfung mit wechselndem Luftdruck und Besprühen mit Wasser

Diese Europäische Norm legt ein zusätzliches Prüfverfahren fest, das zur Beurteilung der
Schlagregendichtheit von Vorhangfassaden, sowohl von ortsfesten als auch zu öffnenden Teilen, angewendet
werden kann. Bei der Prüfung handelt es sich um eine ergänzende Prüfung, die nicht für
Klassifizierungszwecke gefordert wird, und sie sollte nur dann angewendet werden, wenn der Projektmanager
deren Notwendigkeit festgelegt hat.
Sie beschreibt, wie die Außenseite des Prüfkörpers einer Vorhangfassade kontinuierlich mit Wasser besprüht
und einem turbulenten Luftstrom, einschließlich kontinuierlich im Innern der Kammer erzeugten positiven
Luftdruckstößen an der Außenseite des Prüfkörpers, ausgesetzt werden sollte.
Diese Norm gilt für jede Art von Vorhangfassaden, wie sie in EN 13830 festgelegt sind.

Façades rideaux - Etanchéité à l'eau - Essai en laboratoire sous pression d'air dynamique et projection d'eau

La présente Norme européenne définit une autre méthode d'essai qui peut être utilisée pour évaluer l'étanchéité à l'eau des façades rideaux et de leurs parties fixes et manoeuvrables. Il s'agit d'un essai supplémentaire qui n'est pas requis à des fins de classification et qu'il convient d'utiliser uniquement lorsque le prescripteur du projet en a défini la nécessité.
Elle décrit la façon dont il convient que la face externe d'une façade rideau soit soumise à une projection continue d'eau et à un courant d'air turbulent avec impulsions continues de pression d'air positive sur la face externe du corps d’épreuve, générées depuis l'intérieur de la chambre.
Cette Norme s'applique à tous les produits de façades rideaux suivant la définition donnée dans l’EN 13830.

Obešene fasade - Neprepustnost za vodo - Laboratorijski preskus pri dinamičnem tlaku

Ta evropski standard določa dodatne preskusne metode, ki se lahko uporabijo, kadar ocenjujemo neprepustnost za vodo fasade, obešene s pritrjenimi in delno pritrjenimi deli. Gre za dodaten preskus, ki ni potreben za klasifikacijo in ki naj se uporablja samo takrat, kadar določevalec načrta ugotovi, da je potreben. Ta evropski standard opisuje, kako naj bo pročelje vzorca obešene fasade izpostavljeno neprekinjenemu pršenju vode in turbulentnemu zračnemu toku z neprekinjenimi sunki pozitivnega zračnega pritiska na zunanji strani preskusnega vzorca, ustvarjenimi v komori. Ta evropski standard velja za vse proizvode obešenih fasad, kot je določeno v EN 13830.

3.3
watertightness
ability of the curtain walling specimen to resist water leakage

4 Principle
The application of a constant and specified quantity of water in a spray combined with a specified turbulent
airflow and continuous regular pulses of positive test pressure, on to the outside face of the specimen, while
inspecting for water leakage.
5 Apparatus
5.1 A chamber with an opening into which the test specimen can be fitted. This chamber shall be of sufficient
strength and rigidity to withstand the test pressures likely to be imposed during the tests. It shall not deflect
under test pressure to any extent which would affect the performance of the test specimen (Figure 2).

Adequately representative structural supports shall be provided to which the specimen shall be attached in
accordance with the conditions of use in the works (see also Clause 6).

5.2 A means for applying controlled positive test pressures to the specimen arranged such that the air does not
impinge directly on the specimen with any significant velocity.

5.3  A means by which rapidly controlled changes of test pressure may be produced within defined limits.

5.4  A means of measuring the applied test pressures, steady or fluctuation, calibrated within an accuracy of
± 5 %.

5.5  An adjustable device for spraying water at a minimum of 2 l/m²·min so that a constant and continuous film is
applied to the outside surface of the specimen.

The water spraying device shall have nozzles spaced on a regular grid and at a uniform distance from the
outside surface of the specimen (see Figures 3 and 4).

The local mains water supply will be an acceptable source providing it is clean enough to allow the spray nozzles
to function properly throughout the test.

The nozzles shall include the following features:

− Circular full cone spray;

− Spray angle minimum 90° to maximum 120°;

− Working pressure range two to three bars according to the manufacturer’s specification.

5.6 A means of measuring the total amount of water supplied within an accuracy of 10 %.

5.7 A drain for the sprayed water which will not interfere with the drainage of the specimen frame.

5.8 A mobile wind gener
