EN 13111:2010 - Flexible sheets for waterproofing - Underlays for discontinuous roofing and walls - Determination of resistance to water penetration

1 Scope
This European Standard specifies a method to test the resistance against water penetration of underlays for discontinuous roofing and for walls.
2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
EN 13416, Flexible sheets for waterproofing — Bitumen, plastic and rubber sheets for roof waterproofing — Rules for sampling
3 Terms and definitions
For the purposes of this document, the terms and definitions indicated in the corresponding European Standards specifying definitions and characteristics on underlays for discontinuous roofing and walls apply.
4 Principle
Test specimens of the sheet are subjected to a waterhead and the volume of penetrating water is measured.
A conditioned test specimen is positioned as a water-carrying layer into a device with flange and defined basic surface.
Water occasionally penetrating the test specimen will be collected in a basin positioned under the testing apparatus and volumetrically measured at the end of the test.
5 Apparatus
The apparatus is shown in Figure 1 and Table 1.
The test container can have two different inside dimensions with the same test area of 0,045 m 2 :
a) (300 ± 1) mm × (150 ± 1) mm; or
b) (250 ± 1) mm × (180 ± 1) mm.
It is equipped with a flange and a counter frame incorporating a suitable seal.
At the inside of the container, an inclined plane of (45 ± 2)° towards the longitudinal side of the basin is positioned to achieve a defined filling process of the required water quantity. The inclined plane is only attached at the latitudinal sides of 150 mm or 180 mm for containers a) and b) respectively and therefore forms a slot of mm towards the longitudinal side.
6 Sampling and preparation of test specimens
6.1 Sampling Test samples shall be taken in accordance with EN 13416. Samples with extraordinary defects shall not be used for testing.
6.2 Preparation of test specimens Three test specimens with dimension of at least 350 mm × 200 mm or 300 mm × 230 mm for containers a) and b) respectively (see Clause 5) shall be cut from the test sample. The test specimens shall be cut evenly spread across the whole width of the sheet. The prepared test specimens shall be conditioned for 24 h at (23 ± 2) °C before testing.
