Thermal insulating products for building equipment and industrial installations - Determination of short term water absorption by partial immersion of preformed pipe insulation
This European Standard specifies the equipment and procedures for determining the short term water absorption of preformed pipe insulation by partial immersion in water. It is applicable to thermal insulating products.
NOTE It is intended to simulate the water absorption caused by exposure to rain for 24 h during product installation.
If the pipe insulation is cut from a flat product, then the short term water absorption by partial immersion can be obtained from tests carried out on the flat product with similar properties in accordance with EN 1609, providing the test is carried out in the direction giving the highest water uptake.
Wärmedämmstoffe für die Haustechnik und für betriebstechnische Anlagen - Bestimmung der Wasseraufnahme bei kurzzeitigem teilweisem Eintauchen von vorgeformten Rohrdämmstoffen
Diese Europäische Norm legt Prüfeinrichtungen und Verfahren zur Bestimmung der Wasseraufnahme bei kurzzeitigem teilweisem Eintauchen von vorgeformten Rohrdämmstoffen fest. Sie gilt für Wärmedämmstoffe.
ANMERKUNG Mit dem Verfahren kann die Wasseraufnahme simuliert werden, die bei einer 24stündigen Regenperiode während des Einbauens der Produkte auftritt.
Ist die Rohrschale aus einem ebenen Produkt herausgeschnitten worden, kann die Wasseraufnahme bei kurzzeitigem teilweisem Eintauchen aus Prüfungen bestimmt werden, die nach EN 1609 an dem ebenen Produkt mit ähnlichen Eigenschaften durchgeführt werden, vorausgesetzt, die Prüfung wird in Richtung der höchsten Wasseraufnahme durchgeführt.
Produits isolants thermiques pour l'équipement du bâtiment et les installations industrielles - Détermination de l'absorption d'eau à court terme par immersion partielle des coquilles isolantes préformées
Cette Norme européenne spécifie l'équipement et les procédures à suivre pour déterminer l'absorption d'eau
à court terme par immersion partielle de coquilles isolantes préformées. Elle s'applique aux produits isolants
thermiques.
NOTE Elle est destinée à simuler l'absorption d'eau causée par l’exposition à la pluie pendant 24 h, lors de la mise
en oeuvre du produit.
Si la coquille isolante est découpée dans un produit plat, l'absorption d'eau à court terme par immersion
partielle peut être déterminée à partir d'essais effectués selon l’EN 1609 sur le produit plat possédant des
propriétés semblables, à condition que l’essai soit effectué dans le sens donnant l’absorption d’eau la plus
élevée.

EN 13467, Thermal insulating products for building equipment and industrial installations Determination of dimensions, squareness and linearity of preformed pipe insulation 3 Terms and definitions This European Standard contains no terms and definitions. 4 Principle The short term water absorption by partial immersion is determined by measuring the change in mass of a test specimen, the lower part of which is in contact with water for a period of 24 h. The excess water adhering to the surface and not absorbed by the test specimen is drained off in method A, or calculated in method B, from the initial water uptake. 5 Apparatus 5.1 Balance capable of determining the mass of a test specimen to an accuracy of 0,1 g or 0,5 %, whichever is less. 5.2 Water tank with a device for keeping the water level constant to within ± 2 mm, and a device to keep the test specimen in the required position during the test (see examples in Figures 1a) and 1b)).
The supporting device shall be such that the test specimen contact area with water shall be at least 85 % and such that the original form of the test specimen is maintained. 5.3 Tap water adjusted to a temperature of (23 ± 5) °C. In case of dispute, deionised water shall be used. 5.4 Equipment for drainage (see examples in Figures 2a) and 2b)). SIST EN 13472:2013

In the event that the outside diameter of the product is ≤ 300 mm, the test specimen shall have one face with an area equal to the full cross sectional area of the product or half the original cross sectional area. For products with outside diameters > 300 mm, the face shall be a segment of the cross section with an outside chord length of (300 ± 10) mm. The length of the test specimen shall be adjusted so that the area of the immersed cylindrical surface will be (40 000 ± 400) mm². 6.2 Preparation of test specimens The test specimens shall be cut so that they do not include product ends. The test specimens shall be prepared by methods that do not change the original structure of the product. Any skins, facings and/or coatings shall be retained. NOTE Special methods of preparation, when needed, are specified in the relevant product standard. For products with a thickness < 25 mm, the ends shall be closed to avoid water pickup on the inner main surface of the test specimen (e.g. by use of glued aluminium foil on the ends). 6.3 Number of test specimens The number of test specimens shall be as specified in the relevant product standard. If the number is not specified, then at least three test specimens shall be used. In the absence of a product standard or any other European Technical Specification, the number of test specimens may be agreed between parties. SIST EN 13472:2013
In the absence of a product standard or any other European Technical Specification, the method A or B may be agreed between parties. The dimensions of the test specimens shall be measured in accordance with EN 13467. 7.2.2 Method A (drainage) Weigh the test specimen to the nearest 0,1 g or 0,5 %, whichever is less, to determine its initial mass m0. Place the test specimen with the outside surface downwards in the empty water tank and apply a sufficient load to keep the test specimen partially immersed when water is added. Carefully adjust the water added to the tank until the lowest point of the outside face of the test specimen is (20 ± 2) mm below the surface of the water (see examples in Figures 1a) and 1b)). Ensure that the water level remains constant during the test. Remove the test specimen after 24 h and drain it for (10 ± 0,5) min by placing it supported on the exterior surface on a mesh, inclined at 45°, as shown in Figure 2a) or 2b). Weigh the test specimen again to determine the mass m24. 7.2.3 Method B (deduction of initial water uptake) Weigh the test specimen to the nearest 0,1 g or 0,5 %, whichever is less, to determine its initial mass m0. Place the test specimen with the outside surface downwards in the water tank in such position that it is partially immersed in water with the lowest point of the outside face of the test specimen (20
