(Main)Thermal insulating products for building equipment and industrial installations - Determination of short term water absorption by partial immersion of preformed pipe insulation
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 prefor-med pipe insulation by partial immersion in water. It is applicable to thermal insula-ting pro-ducts.
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
Anwendungsbereich
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 a court terme par immersion partielle des coquilles isolantes préformées
Cette Norme européenne spécifie l'équipement et les procédures a utiliser pour déterminer l'absorption d'eau a court terme par immersion partielle de coquilles isolantes préformées. Elle s'applique aux produits isolants thermiques.
NOTE Elle est destinée a simuler l'absorption d'eau causée par l'exposition a 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 a court terme par immersion partielle peut etre déterminée a partir d'essais effectués selon l'EN 1609 sur le produit plat possédant des propriétés similaires, a condition que l'essai soit effectué dans le sens donnant l'absorption d'eau la plus élevée.

EN 13472:2001 (E)3ForewordThis European Standard has been prepared by Technical Committee CEN/TC 88 "Thermal insulatingmaterials and products", the secretariat of which is held by DIN.This European Standard shall be given the status of a national standard, either by publication of anidentical text or by endorsement, at the latest by March 2002, and conflicting national standards shall bewithdrawn at the latest by March 2002.This European Standard is one of a series of standards which specify test methods for determiningdimensions and properties of thermal insulating materials and products. It supports a series of productstandards for thermal insulating materials and products which derive from the Council Directive of 21December 1988 on the approximation of laws, regulations and administrative provisions of the MemberStates relating to construction products (Directive 89/106/EEC) through the consideration of the essentialrequirements.This standard contains one informative annex:Annex A - Table with examples of calculation of the length of the test specimensThis European Standard has been prepared for products used to insulate building equipment andindustrial installations, but it may also be applied to products used in other areas.No existing European Standard is superseded.According to the CEN/CENELEC Internal Regulations, the national standards organizations of thefollowing countries are bound to implement this European Standard: Austria, Belgium, Czech Republic,Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway,Portugal, Spain, Sweden, Switzerland and the United Kingdom.SIST EN 13472:2002

Terms and definitionsThis European Standard contains no terms and definitions.4
PrincipleThe short term water absorption by partial immersion is determined by measuring the change in mass ofa 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 of in methodA or calculated, in method B, from the initial water uptake.5
Apparatus5.1
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 tokeep the test specimen in the required position during the test (see examples in Figures 1a) and 1b)). Thesupporting device shall be such that the test specimen contact area with water shall be at least 85 % andsuch that the original form of the test specimen is maintained.5.3
Tap water adjusted to a temperature of (23 ± 5) C.5.4

Test specimens6.1
Dimensions of test specimensTest specimens shall be prepared from the product without reducing the original thickness. In the eventthat the outside diameter of the product is
300 mm the test specimen shall have one face with an areaequal to the full cross sectional area of the product or half the original cross sectional area. For productswith outside diameters
300 mm the face shall be a segment of the cross section with an outside chordlength of (300 ± 10) mm.The length of the test specimen shall be adjusted so that the area of the immersed cylindrical surface willbe (40 000 ± 400) mm².6.2
Preparation of test specimensThe 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 s
