Glass in building - Coated glass - Part 3: Requirements and test methods for class C and D coatings

This European Standard specifies requirements and a test method related to resistance to solar radiation for coated glass for use in buildings.
This test is aimed at evaluating if the exposure to solar radiation over an extended period of time produces any appreciable change in light transmittance and solar transmittance of the coated glass as well as a reduction of the infrared reflectance in the case of low emissivity coatings.
This European Standard applies to Class C and D coatings as defined in EN 1096-1 and used in insulating glass units.

Glas im Bauwesen - Beschichtetes Glas - Teil 3: Anforderungen an und Prüfverfahren für Beschichtungen der Klassen C und D

Diese Europäische Norm legt Anforderungen und ein Prüfverfahren für die Beständigkeit gegen Sonnenbestrahlung für Beschichtungen auf Glas für die Anwendung im Bauwesen fest.
Diese Prüfung hilft bei der Beurteilung, ob über einen ausgedehnten Zeitraum die Belastung durch Sonnenbestrahlung zu beträchtlichen Veränderungen des Licht- und Sonnenenergietransmissionsgrades des beschichteten Glases und bei Beschichtungen mit geringem Emissionsvermögen zu einer Verringerung des Infrarotreflexionsgrades führt.
Diese Europäische Norm ist, wie in EN 1096-1 festgelegt, auf Beschichtungen der Klassen C und D anwendbar.

Verre dans la construction - Verre à couche - Partie 3: Exigences et méthodes d'essai pour les couches C et D

La présente Norme européenne spécifie les exigences et une méthode d’essai de la résistance au rayonnement solaire applicables au verre à couche employé dans la construction.
Cet essai a pour objectif d’évaluer si l’exposition prolongée du verre à couche au rayonnement solaire produit un changement sensible quelconque dans les facteurs de transmission lumineuse et de transmission de l’énergie solaire, ainsi qu’une réduction de la réflexion infrarouge dans le cas de couches à basse émissivité.
La présente Norme européenne s’applique aux couches de classes C et D telles que définies dans
l’EN 1096-1 et utilisées dans les vitrages isolants préfabriqués scellés.

Steklo v gradbeništvu - Steklo z nanosi - 3. del: Zahteve in preskusne metode za nanose razredov C in D

Ta evropski standard določa zahteve in preskusne metode v zvezi z odpornostjo na sončno sevanje za steklo z nanosi, ki se uporablja v gradbeništvu. S tem preskusom se določa, ali izpostavljenost sončnemu sevanju skozi daljše časovno obdobje povzroča občutne spremembe v svetlobni in solarni prehodnosti stekla z nanosi ter zmanjšanje infrardečega odboja v primeru nanosov nizke emisivnosti. Ta evropski standard se uporablja za nanose razredov C in D iz standarda EN 1096-1, ki se uporabljajo pri izolacijskih steklih.

The dew point of the test specimens shall not be higher than - 25°C, when measured at
(23 ± 5) °C, according to EN 1279-2:2002, Annex A, or equivalent. The dew point is ensured when the insulating glass unit is manufactured in accordance with the EN 1279 series. The edge area of the test specimens shall be covered with a reflecting aluminium foil (40 ± 5) mm wide as a means of protection for the sealant components. 6 Initial evaluation of the test pieces The external surfaces of the test pieces shall be cleaned with a soft tissue using demineralised water, having a conductivity lower than 30 µS. Drying shall also be done with a soft tissue. If necessary this cleaning procedure can be repeated. SIST EN 1096-3:2012
