Glass in building - Determination of thermal transmittance (U value) - Heat flow meter method
This European Standard specifies a measuremnet procedure used to determine the thermal transmittance of glazing with flat and parallel surfaces. Structured surfaces, e.g. patterned glass, may be considered to be flat. This European Standard applies to multiple glazing with outer panes which are not transparent to far infrared radiation, which is the case for soda lime glass products, borosilicate glass and glass ceramics. Internal elements can be far infrared transparent.
Glas im Bauwesen - Bestimmung des Wärmedurchgangskoeffizienten (U-Wert) - Wärmestrommesser-Verfahren
Diese Europäische Norm beschreibt ein Meßverfahren, das zur Bestimmung des Wärmedurchgangskoeffizienten von Verglasungen mit ebenen und parallelen Oberflächen dient. Strukturierte Oberflächen, z.B. Ornamentglas, dürfen ebenfalls als eben angesehen werden. Diese Europäische Norm gilt für Mehrfachverglasungen mit äußeren Scheiben, die für Strahlung im fernen Infrarotbereich undurchlässig sind, was bei Produkten aus Natron-Kalk-Glas, Borosilicatglas und Glaskeramik der Fall ist. Innere Elemente können jedoch für Strahlung im fernen Infrarotbereich durchlässig sein.
Verre dans la construction - Détermination du coefficient de transmission thermique, U - Méthode du fluxmètre
La présente norme européenne spécifie une méthode de mesure utilisée pour déterminer le coefficient de transmission thermique, U, de vitrages dont les faces sont planes et parallèles. Les surfaces des verres coulés et imprimés peuvent être considérées comme planes. La présente norme européenne est applicable aux vitrages multiples dont les faces externes ne sont pas transparentes au rayonnement infrarouge lointain, ce qui est le cas du verre sodocalcique, du verre borosilicate et du verre céramique. Toutefois, les éléments internes peuvent être transparents au rayonnement infrarouge lointain.
