22、lomerated stones when in contact with water. This European Standard applies to agglomerated stones to be installed by adhesive on walls and floors. The test is mainly performed to classify the material according to the degree of sensitivity to water and to select a suitable adhesive for the correct

23、laying of agglomerated stones. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the reference

24、d document (including any amendments) applies. Not applicable. 3 Principle The principle of this method consists in measuring the vertical displacement of one corner of the tile using a wet felt placed on the backside of the agglomerated stone to simulate the contact with water. A series of sensors

25、carries out the measurement of the deformation caused by the humidity released by the cloth. 4 Apparatus 4.1 A suitable instrument (see Figure 1) consisting of: 4.1.1 A flat and smooth reference plane. 4.1.2 Three supports for the tile. 4.1.3 Four digital gauges with an accuracy of 0,01 mm for the n

26、ormative part (see Figure 1). For the informative part see Annex B where five digital gauges are required. 4.2 A cloth or a felt. 4.3 A water spray dispenser. 4.4 A polyethylene film.

28、depending on the size and thickness of the tile, as well as on its humidity content. BS EN 14617-12:2012EN 14617-12:2012 (E) 7 Therefore, in order to obtain reliable results: the size of the tile shall be 300 mm 300 mm with the same thickness used for installation; NOTE For thicknesses below 12 mm,

29、considering that these types of tiles are not self-supporting, testing should be carried out in accordance with Annex A. before being tested, the test specimens shall be stored separately, in vertical position, for at least 24 h under standard conditions. (For tiles that are very wet before storage

30、in standard conditions, it is necessary to dry the test specimens for 12 h at 50 C.) 7 Test procedure Before testing the sample, check its planarity. The tile shall be placed upside down on the three supports (4.1.2) that are positioned on the reference plane (4.1.1) near the corners and fixed with

31、the weight or the clamp (Y). Four digital gauges are to be positioned in contact with the tile as showed in Figure 1. Digital gauge (M3), placed at 5 mm from both sides of the corner, measures the deformation of the free corner, while digital gauge (M1) measures the deformation at the centre of the

32、tile. Digital gauges (M2) and (M4) measure the tile expansion. A wet cloth or felt (F), reproducing the humidity of a traditional mortar bed or of a cementitious adhesive, is placed on the back of the tile and a polyethylene film (G) is placed over the felt to avoid fast evaporation. During the test

33、 the cloth or the felt shall be kept constantly wet by a water spray dispenser. Deformations are recorded from the digital gauges (4.1.3) after a period of 6 h. 8 Expression of results 6 h after applying the wet felt the deformation is determined to an accuracy of 0,1 mm using the following formula:

34、 D = |d(3) d(1)| (1) where D is the vertical displacement; d(3) is the deformation measured by digital gauge (3); d(1) is the deformation measured by digital gauge (1). According to the measured deformation in any of the sizes of tiles tested, the agglomerated stones are classified as in Table 1. BS
