EN 12412-4:2003

Thermal performance of windows, doors and shutters - Determination of thermal transmittance by hot box method - Part 4: Roller shutter boxes

This European Standard specifies a method, based on EN ISO 8990 and EN ISO 12567-1, to measure the overall thermal transmittance of a roller shutter box in a hot box. This includes all effects of geometrical and material characteristics in a test specimen.
Edge effects occurring outside of the perimeter of the specimen are excluded. Furthermore, energy transfer due to solar radiation is not taken into account, and air leakage is excluded.
The method is designed to provide both standardised tests which enable a fair comparison of different products to be made, and specific tests on products for practical application purposes. The former includes window standardised specimen sizes and applied test criteria.
The determination of the overall thermal transmittance is performed for conditions which will correspond to a similar situation of the roller shutter box in practice.
Information on the design of the calibration transfer standard is given in EN ISO 12567-1.

Wärmetechnisches Verhalten von Fenstern, Türen und Abschlüssen - Bestimmung des Wärmedurchgangskoeffizienten mittels des Heizkastenverfahrens - Teil 4: Rollladenkästen

Diese Norm legt ein Verfahren zur Messung des Wärmedurchgangskoeffizienten von Rollladenkästen mittels eines Heizkastens fest, das auf EN ISO 8990 und prEN 12412-1 basiert. Dies umfasst sämtliche Auswirkungen der geometrischen und stofflichen Kenngrößen in einem Probekörper.
Randeinflüsse, die außerhalb des Umfangs des Probekörpers wirksam sind, werden ausgeschlossen. Weiterhin wird die Energieübertragung infolge Sonnenstrahlung nicht berücksichtigt, und Luftundichtigkeit ist ebenfalls nicht Gegenstand dieser Norm.
Das Verfahren ist für zwei Anwendungen geeignet:
¾ Norm-Prüfungen, die einen Vergleich verschiedener Produkte ermöglichen und
¾ Sonderprüfungen an Probekörpern in der jeweiligen praktischen Anwendung.
Für die Norm-Prüfung sind genormte Probekörper-Masse und Prüfkriterien vorgeschrieben.
Die Bestimmung des Wärmedurchgangskoeffizienten wird bei Bedingungen durchgeführt, die mit den Einsatz-bedingungen des Rollladenkastens in der Praxis vergleichbar sind.

Performance thermique des fenêtres, portes et fermetures - Détermination du coefficient de transmission thermique par la méthode de la boîte chaude - Partie 4: Coffres de volets roulants

La présente Norme européenne spécifie une méthode fondée sur les EN ISO 8990 et EN ISO 12567-1, pour mesurer le coefficient de transmission thermique globale d'un coffre de volet roulant dans une boîte chaude. Ceci comprend tous les effets des caractéristiques géométriques et des matériaux d'une éprouvette.
Les effets de bord se produisant à l'extérieur du périmètre de l'éprouvette sont exclus. De plus, le transfert d'énergie dû au rayonnement solaire n'est pas pris en compte, et les fuites d'air sont exclues.
La méthode est conçue pour fournir à la fois des essais normalisés permettant une comparaison équitable entre différents produits et des essais spécifiques sur des produits en vue de certaines applications pratiques. Les premiers prescrivent des tailles normalisées pour les éprouvettes de fenêtres et des critères d'essai appliqués.
La détermination du coefficient de transmission thermique globale est réalisée dans des conditions proches de celles de la pratique.
Les informations relatives à la conception de l'étalon de transfert de calibration figurent dans l'EN ISO 12567-1.

4 Principle
Tests are carried out using the calibrated or guarded hot box in accordance with EN ISO 8990 and EN ISO 12567-
1. Depending on the height of the box, roller shutter boxes located in pairs of the same type of construction
equipped with masks (simulation of window frames) form the test specimen.
The surround panel is used to keep the specimen in position. It is constructed with outer dimensions of appropriate
size for the apparatus, having an aperture to accommodate the specimen (see Figures 1 and 2).
The principal heat flows through the surround panel and the calibration panel (or test specimen) are shown in
Figure 3. The boundary edge heat flow due to the location of the calibration panel in the surround panel is
determined separately by a linear thermal transmittance Y .
The procedure in this standard includes a correction for the boundary edge heat flow, so that standardized and
reproducible thermal transmittance properties are obtained.
The magnitude of the boundary edge heat flow as a function of geometry, calibration panel thickness and thermal
conductivity is determined by tabulated values given in annex B.
