DIN EN 14617-12:2012-06 According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark,

This Euro
25、pean 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 laying of agglomerated stones. 2 Normative references
26、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 referenced document (including any amendments) applies. Not app
27、licable. 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 carries out the measurement of the deformation caused
28、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 normative part (see Figure 1). For the informative part
29、 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.

31、as well as on its humidity content. DIN EN 14617-12:2012-06 EN 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, considering that these types of tiles are no
32、t 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 in standard conditions, it is necessary to d
33、ry 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 the weight or the clamp (Y). Four digital ga
34、uges 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 tile. Digital gauges (M2) and (M4) measure t
35、he 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 the cloth or the felt shall be kept constan
36、tly 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: D = |d(3) d(1)| (1) where D is the vertical
37、 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. DIN EN 14617-12:2012-06 EN 14617-12:2012 (E) 8

Class C The material is “very” sensitiv
39、e to contact with water. For the installation a water-free, reaction resin adhesive (type R according to EN 12004) should be used.
