Thermal insulating products for building applications - Determination of long term water absorption by immersion
This European Standard specifies the equipment and procedures for determining the long-term water absorption of test specimens. It is applicable to thermal insulating products.
This European Standard specifies two options:
- Method 1 - partial immersion
- Method 2 - total immersion
The long-term water absorption by partial immersion is intended to simulate the water absorption caused by long term water exposure.
The long-term water absorption by total immersion is not directly related to the conditions on site, but has been recognised as a relevant condition of test for some products in some applications.
Wärmedämmstoffe für das Bauwesen - Bestimmung der Wasseraufnahme bei langzeitigem Eintauchen
Diese Europäische Norm legt Prüfeinrichtungen und Verfahren zur Bestimmung der langzeitigen Wasseraufnahme von Probekörpern fest. Sie gilt für Wärmedämmstoffe.
Diese Europäische Norm legt zwei Prüfverfahren zur Auswahl fest:
- Prüfverfahren 1: teilweises Eintauchen
- Prüfverfahren 2: vollständiges Eintauchen
Die langzeitige Wasseraufnahme bei teilweisem Eintauchen simuliert die Wasseraufnahme, die sich bei langzeitigem Einwirken von Wasser ergibt.
Die langzeitige Wasseraufnahme bei vollständigem Eintauchen kann zwar nicht direkt mit den Anwendungsbeanspruchungen verglichen werden, es wurde aber als entsprechende Prüfbedingung für bestimmte Produkte bei manchen Anwendungen anerkannt.
Produits isolants thermiques destinés aux applications du bâtiment - Détermination de l'absorption d'eau à long terme par immersion
La présente Norme européenne spécifie l'équipement et les modes opératoires permettant de déterminer l'absorption d'eau à long terme des éprouvettes. Elle s'applique aux produits isolants thermiques.
La présente Norme européenne spécifie deux options :
- Méthode 1 - immersion partielle
- Méthode 2 - immersion totale
L'absorption d'eau à long terme par immersion partielle est destinée à simuler l'absorption d'eau causée par une exposition prolongée à l'eau.
L'absorption d'eau à long terme par immersion totale n'est pas directement liée aux conditions sur site, mais a été reconnue comme étant une condition d'essai pertinente pour certains produits dans certaines applications.
Toplotnoizolacijski proizvodi za uporabo v gradbeništvu - Ugotavljanje dolgotrajnega vpijanja vode - Preskus s potapljanjem
Ta evropski standard določa opremo in postopke za ugotavljanje dolgotrajnega vpijanja vode preskušancev. Uporablja se za toplotnoizolacijske proizvode. Ta evropski standard določa dve možnosti: Metoda 1 – delno potapljanje; metoda 2 – popolno potapljanje. Dolgotrajno vpijanje vode z delnim potapljanjem simulira vpijanje vode pri dolgotrajni izpostavljenosti vodi. Dolgotrajno vpijanje vode s popolnim potapljanjem ni neposredno povezano s pogoji na mestu uporabe, ampak se smatra kot ustrezen pogoj preskusa za nekatere proizvode pri nekaterih uporabah.

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 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 12087:2013

4.1 Partial immersion (method 1)
The long-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 28 days. The excess water adhering to the surface, not absorbed by the test specimen, is removed by drainage in method 1A or taken into account by deduction of the initial water uptake in method 1B. 4.2 Total immersion (method 2)
The long term water absorption by total immersion is determined by measuring the change in mass of the test specimen, totally immersed in water, over a period of 28 days.
The excess water adhering to the surface, not absorbed by the test specimen, is removed by drainage in method 2A or taken into account by deduction of the initial water uptake in method 2B. 5 Apparatus
5.1 Balance, which allows the determination of the mass of a test specimen to 0,1 g. 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.
