Glass in building - Insulating glass units - Part 2: Long term test method and requirements for moisture penetration
This draft European Standard is the product standard fo insulating glass units, which defines insulating glass units, and ensures by means of an adequate evaluation of conformity to this standard that: - energy savings are made because the U-value and solar factor do not change significantly; - health because sound reduction and vision do not change significantly; - safety is provided because mechanical resistance does not change significantly.
Glas im Bauwesen - Mehrscheiben-Isolierglas - Teil 2: Langzeitprüfverfahren und Anforderungen bezüglich Feuchtigkeitsaufnahme
Diese Europäische Norm legt Anforderungen für die Feuchtigkeitsaufnahme und das Langzeitprüfverfahren für Mehrscheiben-Isoliergläser fest und stellt durch eine adäquate Bewertung der Übereinstimmung mit dieser Norm sicher, dass:
Energieeinsparungen erzielt werden, da keine signifikanten Änderungen des U-Werts und des Solarfaktors auftreten;
die Gesundheitsvorsorge gefördert wird, da keine signifikanten Änderungen der Schalldämmung und der Durchsicht auftreten;
der Sicherheit gedient wird, da keine signifikanten Änderungen der mechanischen Beständigkeit auftreten.
Dieser europäische Normentwurf deckt zusätzliche Merkmale ab, die für den Handel von Bedeutung sind. Die Bedingungen für die Kennzeichnung werden ebenfalls erfasst.
Bei den Glasprodukten mit elektrischer Verkabelung oder elektrischen Anschlüssen, z. B. für Alarmanlagen oder Heizsysteme, gilt diese Norm nur für Verkabelungen mit einem elektrischen Potenzialunterschied zur Erde von weniger als 50 V Wechselstrom oder weniger als 75 V Gleichstrom.
Der Haupteinsatzbereich der Mehrscheiben-Isoliergläser sind Fenster, Türen, Vorhangfassaden, Dachkonstruktionen und Trennelemente, deren Kanten gegen direkte UV-Strahlung geschützt sind.
ANMERKUNG 1 Falls die Kanten nicht gegen direkte UV-Strahlung geschützt sind, wie z. B. bei geklebten Glaskonstruktionen ("structural sealant glazing"-Systeme), sind zusätzliche europäische technische Spezifikationen zu befolgen.
ANMERKUNG 2 Mehrscheiben-Isoliergläser rein künstlerischer Natur werden von dieser Norm nicht erfasst.
Dieser Teil der Norm, der nur in Verbindung mit den anderen Teilen der Norm gilt, umfasst die Prüfung der Feuchtigkeitsaufnahme als ein Mittel zur Überprüfung, ob ein nach seiner Systembeschreibung hergestelltes Erzeugnis in dieser Hinsicht der Definition von Mehrscheiben-Isolierglas entspricht.
Verre dans la construction - Vitrage isolant préfabriqué scellé - Partie 2: Méthode d'essai de longue durée et exigences en matière de pénétration d'humidité
La présente Norme européenne spécifie les exigences en matière de pénétration d'humidité et la méthode d'essai de longue durée des vitrages isolants préfabriqués scellés et assure, au moyen d'une évaluation appropriée de la conformité à la présente norme dans le temps :
des économies d'énergie car la valeur U et le coefficient solaire ne changent pas de manière significative ;
une protection de la santé car l'affaiblissement acoustique et l'aspect visuel ne changent pas de manière significative ;
la sécurité car la résistance mécanique ne change pas de manière significative.
Elle couvre des caractéristiques supplémentaires d'importance pour le commerce. Les conditions de marquage sont incluses.
Pour les produits verriers équipés d'un câblage ou de branchements électriques pour les besoins d'alarme ou de chauffage par exemple, la présente norme couvre uniquement les éléments de câblage prévus pour une différence de potentiel électrique à la terre inférieure à 50 V c.a. ou inférieure à 75 V c.c.
Les usages prévus des vitrages isolants préfabriqués scellés sont principalement des installations dans des bâtiments et des constructions telles que sur des fenêtres, des portes, des façades-rideaux, des plafonds et des cloisons lorsqu'il existe une protection contre les rayonnements ultraviolets directs sur les bords.
NOTE 1 En l'absence de protection contre les rayonnements ultraviolets directs sur les bords, telle que des matériaux verriers de scellement structurel, il convient de se conformer aux spécifications techniques européennes supplémentaires.
NOTE 2 Les vitrages de nature purement artistique ne sont pas couverts par la présente norme.
La présente partie de la norme, qui est indissociable des autres parties de la présente norme, considère les essais de pénétration d'humidité comme un moyen de vérifier qu'un produit fabriqué conformément à sa description du système est conforme à l'aspect correspondant de la définition des vitrages isolants préfabriqu
