Thermal insulating products for building applications - Determination of long term water absorption by diffusion
This European Standard specifies the equipment and procedures for determining the long-term water absorption of test specimens by diffusion. It is applicable to thermal insulating products. It is intended to simulate the water absorption of products subjected to high relative humidities, approximating to 100 %, on both sides and subjected to a water vapour pressure gradient for a long period of time e.g. inverted roof or unprotected ground insulation.
The test is not applicable for all types of thermal insulating products. The product standard should state for which of its products, if any, this test is applicable.
NOTE For unprotected ground insulation, the temperature of 50 C might be replaced by a lower temperature, when more data is available.
Wärmedämmstoffe für das Bauwesen - Bestimmung der Wasseraufnahme durch Diffusion
Diese Europäische Norm legt Prüfeinrichtungen und Verfahren zur Bestimmung der langzeitigen Wasseraufnahme von Probekörpern durch Diffusion fest. Sie gilt für Wärmedämmstoffe. Das Prüfverfahren simuliert die Wasseraufnahme von Produkten, die auf beiden Seiten einer hohen relativen Luftfeuchte bis 100 % sowie über eine lange Zeit einer Wasserdampfteildruckdifferenz ausgesetzt werden, wie z. B. im „Umkehrdach“ oder bei der ungeschützten Wärmedämmung zum Erdreich.
Dieses Prüfverfahren ist nicht für alle Typen von Wärmedämmstoffen anwendbar. Daher sollte in der entsprechenden Produktnorm angegeben werden, für welche der in ihr beschriebenen Produkte dieses Prüfverfahren anwendbar ist.
ANMERKUNG Für „ungeschützte Wärmedämmung zum Erdreich“ kann möglicherweise die Temperatur von 50 °C durch eine niedrigere Temperatur ersetzt werden, wenn mehr Daten zur Verfügung stehen.
Produits isolants thermiques destinés aux applications du bâtiment - Détermination de l'absorption d'eau à long terme - Essai par diffusion
La présente Norme européenne spécifie l'équipement et les modes opératoires permettant de déterminer l'absorption d'eau à long terme des éprouvettes par diffusion. Elle s'applique aux produits isolants thermiques. Elle est destinée à simuler l'absorption d'eau de produits soumis à des taux d'humidité relative élevés, proches de 100 % sur chacune des faces ainsi qu'à un gradient de pression de vapeur d'eau pendant une longue durée, par exemple une toiture inversée ou une isolation au contact direct de la terre.
L'essai ne s'applique pas à tous les types de produits isolants thermiques. Il convient que la norme produit stipule à quels produits s'applique, le cas échéant, le présent essai.
NOTE Pour une isolation au contact direct de la terre, la température de 50 C pourrait être remplacée par une température inférieure, lorsque davantage de données seront disponibles.
Toplotnoizolacijski proizvodi za uporabo v gradbeništvu - Ugotavljanje dolgotrajnega vpijanja vode - Preskus z difuzijo
Ta evropski standard določa opremo in postopke za ugotavljanje dolgotrajnega vpijanja vode preskušancev z difuzijo. Uporablja se za toplotnoizolacijske proizvode. Namenjen je simulaciji vpijanja vode pri proizvodih, ki so izpostavljeni visoki vlagi, približno 100 %, na obeh straneh in dolgotrajnemu gradientu parnega tlaka vode, npr. pri invertnih strehah in nezaščiteni talni izolaciji. Preskus ni priporočljiv za vse vrste toplotnoizolacijskih proizvodov. Standard za proizvod mora navajati, za katere proizvode je preskus uporaben (če obstajajo).

The revision of this standard contains no major changes, only minor corrections and clarifications of an editorial nature. This European Standard is one of a series of standards which specify test methods for determining dimensions and properties of thermal insulating materials and products. It supports a series of product standards for thermal insulating materials and products which derive from the Council Directive of 21 December 1988 on the approximation of laws, regulations and administrative provisions of the Member States relating to construction products (Directive 89/106/EEC) through the consideration of the essential requirements. This European Standard has been drafted for applications in buildings but it may also be used in other areas where it is relevant. This European test standard is one of the following group of inter-related standards on test methods for determining dimensions and properties of thermal insulation materials and products, all of which fall within the scope of CEN/TC 88: EN 822, Thermal insulating products for building applications — Determination of length and width EN 823, Thermal insulating products for building applications — Determination of thickness EN 824, Thermal insulating products for building applications — Determination of squareness EN 825, Thermal insulating products for building applications — Determination of flatness EN 826, Thermal insulating products for building applications — Determination of compression behaviour EN 1602, Thermal insulating products for building applications — Determination of the apparent density EN 1603, Thermal insulating products for building applications — Determination of dimensional stability under constant normal laboratory conditions (23 °C/50 % relative humidity) EN 1604, Thermal insulating products for building applications — Determination of dimensional stability under specified temperature and humidity conditions EN 1605, Thermal insulating products for building applications — Determination of deformation under specified compressive load and temperature conditions EN 1606, Thermal insulating products for building applications — Determination of compressive creep SIST EN 12088:2013
