EN 14500:2008

Blinds and shutters - Thermal and visual comfort - Test and calculation methods

This European Standard defines test and calculation methods for the determination of the reflection and transmission characteristics to be used to determine the thermal and visual comfort performance classes of external blinds, internal blinds and shutters, as specified in EN 14501.
This European Standard also specifies the method to determine opacity characteristics of dim-out/black-out external blinds, internal blinds and shutters, as specified in EN 14501.
This European Standard applies to the whole range of shutters, awnings and blinds defined in EN 12216, described as solar protection devices in this European Standard. Some of the characteristics (e.g. gtot) are not applicable when products are not parallel to the glazing (e.g. folding-arm awnings).
NOTE   Informative Annex D presents an approach for the determination of characteristics in case of projectable products.
Products using fluorescent or retroreflecting materials are outside the scope of this European Standard.

Abschlüsse - Thermischer und visueller Komfort - Prüf- und Berechnungsverfahren

Diese Europäische Norm definiert Prüf  und Berechnungsverfahren zur Bestimmung der Reflexions  und Transmissionskenngrößen, die anzuwenden sind, um die Leistungsklassen von innen und außen liegenden Abschlüssen hinsichtlich des thermischen und visuellen Komforts nach den Festlegungen in EN 14501 zu bestimmen.
Diese Europäische Norm legt auch das Verfahren zur Bestimmung der Lichtundurchlässigkeitskenngrößen von innen und außen liegenden Abdunkelungs /Verdunkelungsanlagen nach den Festlegungen in EN 14501 fest.
Diese Europäische Norm gilt für das gesamte Sortiment von Abschlüssen, Markisen und Jalousien, die in EN 12216 definiert sind und in dieser Europäischen Norm als Sonnenschutzeinrichtungen beschrieben werden. Einige der Kenngrößen (z. B. gtot) sind nicht anwendbar, wenn die Produkte nicht parallel zur Verglasung angebracht sind (z. B. Gelenkarm Markisen).
ANMERKUNG   Der informative Anhang D stellt eine Herangehensweise für die Bestimmung der Kenngrößen im Falle ausstellbarer Produkte dar.
Produkte, die fluoreszierende oder retroreflektierende Materialien verwenden, sind nicht Gegenstand dieser Europäischen Norm.

Fermetures et stores - Confort thermique et lumineux - Méthodes d'essai et de calcul

Cette Norme européenne définit les méthodes d’essai et de calcul permettant la détermination des caractéristiques de réflexion et de transmission à utiliser pour déterminer les classes de performance de confort thermique et lumineux des stores extérieurs, des stores intérieurs et des fermetures pour baies équipées de fenêtres, telles que spécifiées dans l’EN 14501.
Cette Norme européenne spécifie également la méthode permettant de déterminer les performances d’opacité des stores extérieurs, des stores intérieurs et des fermetures pour baies équipées de fenêtres opaques/d’obscurcissement, telles que spécifiées dans l’EN 14501.
Cette Norme européenne s'applique à l'ensemble des fermetures, stores extérieurs et stores intérieurs définis dans l’EN 12216, décrits comme dispositifs de protection solaire dans le présent document. Certaines caractéristiques (par exemple gtot) ne sont pas applicables lorsque les produits ne sont pas parallèles au vitrage (par exemple, les stores bannes).
NOTE   L’Annexe D informative présente une approche pour la détermination des caractéristiques dans le cas de produits projetables.
Les produits qui utilisent des matériaux fluorescents ou rétroréfléchissants ne relèvent pas du domaine d'application de cette norme européenne.
