Thermal insulating products for building equipment and industrial installations - Determination of water vapour transmission properties of preformed pipe insulation
This European Standard specifies the equipment and procedure for determining the water vapour transmission properties in the steady state under specified test conditions for test specimens of preformed pipe insulation. It is applicable to thermal insulating products.
It is intended to be used for homogeneous materials (see NOTE) and for products which may have integral skins or adhered facings of some different material.
NOTE A material is considered to be homogeneous in terms of mass distribution if its density is approximately the same throughout, i.e. if the measured density values are close to its mean density.
The water vapour transmission rate and permeance values are specific to the test specimen (i.e. the product) thickness tested. For homogeneous products, the water vapour permeability is a property of the material.
If the pipe insulation is cut from a flat product, then the water vapour transmission properties can be obtained from tests carried out on the flat product with similar properties in accordance with EN 12086.
Wärmedämmstoffe für die Haustechnik und für betriebstechnische Anlagen - Bestimmung der Wasserdampfdurchlässigkeit von vorgeformten Rohrdämmstoffen
Diese Europäische Norm legt Prüfeinrichtungen und Verfahren zur Bestimmung der Wasserdampf-durchlässigkeits-Eigenschaften von Probekörpern aus vorgeformten Rohrdämmstoffen im stationären Zustand unter definierten Prüfbedingungen fest. Sie gilt für Wärmedämmstoffe.
Die Norm ist anwendbar bei homogenen Dämmstoffen (siehe ANMERKUNG) und bei Produkten, die als festen Bestandteil bestimmte Oberflächenschichten oder Kaschierungen aus anderen Werkstoffen enthalten können.
ANMERKUNG Ein Dämmstoff wird als homogen hinsichtlich seiner Massenverteilung angesehen, wenn seine Dichte überall etwa gleich ist, das heißt, wenn die gemessenen Werte nahe beim Mittelwert seiner Rohdichte liegen.
Die Wasserdampf-Diffusionsstromdichte und der Wasserdampf-Diffusionsdurchlasskoeffizient sind abhängig von der Dicke des geprüften Probekörpers bzw. des Produkts. Für homogene Produkte ist der Wasserdampf-Diffusionsleitkoeffizient eine Stoffeigenschaft.
Ist die Rohrschale aus einem ebenen Produkt herausgeschnitten worden, können die Wasserdampfdurchlässigkeits-Eigenschaften aus Prüfungen bestimmt werden, die nach EN 12086 an dem ebenen Produkt mit ähnlichen Eigenschaften durchgeführt werden.
Produits isolants thermiques pour l'équipement du bâtiment et les installations industrielles - Détermination des propriétés de transmission de la vapeur d'eau des coquilles isolantes préformées
La présente Norme européenne spécifie les équipements nécessaires et les procédures à suivre pour
déterminer à l'équilibre et dans des conditions d'essai spécifiques, les propriétés de transmission de la vapeur
d'eau d’éprouvettes constituées de coquilles isolantes préformées. Elle s'applique aux produits isolants
thermiques.
Elle est destinée aux matériaux homogènes (voir NOTE) et aux produits qui pourraient posséder des
revêtements intégrés ou des parements collés faits d'un autre matériau.
NOTE Un matériau est estimé homogène quant à sa distribution massique si sa densité est à peu près la même
partout, c'est-à-dire si les valeurs mesurées de la densité sont proches de sa densité moyenne.
Le taux de transmission de la vapeur d'eau et le degré de perméance dépendent de l'épaisseur de
l’éprouvette (c'est-à-dire du produit) soumise à l'essai. Dans le cas des produits homogènes, la perméabilité à
la vapeur d'eau est une propriété du matériau.
Si la coquille isolante est découpée dans un produit plat, les propriétés de transmission de la vapeur d'eau
peuvent être déterminées à partir d'essais effectués selon l'EN 12086 sur le produit plat possédant des
propriétés semblables.

quantity of water vapour transmitted per unit of time through a unit area of the product per unit of vapour pressure difference between its faces for a unit thickness Note 1 to entry: Water vapour permeability is a product of the permeance and the thickness of the test specimen (δ = W × d). It is a property of the material of a homogeneous product.
3.6 water vapour diffusion resistance factor µ
quotient of the water vapour permeability of air and the water vapour permeability of the material or the homogeneous product concerned which indicates the relative magnitude of the water vapour resistance of the product and that of an equally thick layer of stationary air at the same temperature 4 Principle A desiccant filled "dry-cup" made from a preformed pipe insulation test specimen is placed in a test atmosphere whose temperature and humidity are controlled. Because of the difference between the partial water vapour pressures in the test assembly and in the test atmosphere, water vapour flows through the test specimen. Periodic weighings of the assembly are made to determine the rate of water vapour transmission when the steady state is reached. 5 Apparatus 5.1 Chamber, capable of being maintained within a temperature of (23 ± 1) °C and a relative humidity (50 ± 3) %. In order to maintain the required conditions throughout the chamber, it may be necessary to use air circulation with an air speed between 0,02 m/s to 0,3 m/s. 5.2 Desiccant, anhydrous calcium chloride (CaCl2) with particle size 2 mm to 15 mm (relative humidity 0 %) or any other desiccant that gives the same results. 5.3 Analytical balance, capable of weighing the test assembly to an accuracy of ± 1 mg or better.
If larger test assemblies are used, the weighing accuracy may be determined with respect to the total weight and the required accuracy of the test results. 5.4 Measuring instruments, capable of determining linear dimensions and thicknesses in accordance with the requirements of EN 12085 or EN 13467, whichever is relevant. 5.5 Aluminium foil, water vapour diffusion tight (at least 50 µm thick) protected with a polymer film on the face in contact with the calcium chloride (CaCl2). 5.6 Adhesive, suitable to make water vapour tight joint between the aluminium foil and the test specimen (see relevant product standard). Any combination of foil or sealant and adhesive, which provides comparable results, may be used. 6 Test specimens 6.1 General The test specimens shall be representative of the product and shall include any natural surface skins or adhered facings of different materials.
