This European Standard is applicable to all ceramic tile adhesives for internal or external tile
17、installations on walls and floors. This European Standard does not contain performance requirements or recommendations for the design and installation of ceramic tiles. NOTE Ceramic tile adhesives can also be used for other types of tiles (natural and agglomerated stones etc.), if they do not advers
18、ely affect the stones. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

The tiles used for this method shall be of the following type: type P1: glazed porous body tile complying
23、with EN 14411, group BIII, of water absorption (15 3) % by mass, with a thickness in the range 7 mm to 10 mm and a profile back pattern less than 0,25 mm deep, cut to facial dimensions of (50 1) mm (50 1) mm. 5.3 Concrete slab The concrete slab shall comply with EN 1323. 6 Apparatus 6.1 Notched trow
24、el A notched trowel having 6 mm 6 mm notches at 12 mm centres. 6.2 Weight A mass capable of exerting a force of (20 0,05) N, with a cross-sectional area of less than 50 mm 50 mm. 6.3 Pull-head plates Square metallic plates, with dimensions of (50 1) mm (50 1) mm and a minimum thickness of 10 mm with
25、 a suitable fitting for connection to the test machine. 6.4 Test machine A test machine for direct pull tensile force test and with suitable capacity and sensitivity for the test. The machine shall be capable of applying the load to the pull-head plate at the rate of (250 50) N/s through a suitable
26、fitting that does not exert any bending force. 7 Mixing of adhesive The amount of water and/or liquid admix required for preparing the adhesive shall be as stated by the adhesive manufacturer in parts by mass, i.e. liquid to dry powder (if a range of values is given, the average shall be used). Prep
27、are a minimum quantity of 2 kg of the adhesive in a mixer of the type described in 4.4 of EN 196-1:2005, using the speed settings (140 5) r/min and (62 5) r/min planetary movement. Carry out the following procedure: pour the liquid into the pan; scatter the dry powder over the liquid; mix for 30 s;
28、take out the mixing paddle; Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 28/02/2008 03:09, Uncontrolled Copy, (c) BSIEN 1346:2007 (E) 6 scrape down the paddle and pan within 1 min; replace the paddle and mix for 1 min. Let the adhesive mature in accordance with the adhesive manufacturers i
29、nstructions and then mix for a further 15 s. In the case of ready-to-use dispersion adhesives or reaction resin adhesives, the manufacturers instructions shall be followed. 8 Procedure Apply a thin layer of the adhesive, mixed in accordance with Clause 7, to the concrete slab with a straight edge tr
30、owel. Then apply a thicker layer and comb with the notched trowel (6.1). Hold the trowel at an angle of approximately 60 to the substrate at a right angle to one edge of the slab and drawn across the slab parallel to that edge (in a straight line). After 5 min, 10 min, 20 min and 30 min place at lea
31、st ten test tiles of type P1, 50 mm apart, on the adhesive and load each tile with (20 0,05) N for 30 s. After 27 days storage under standard conditions, bond the pull-head plates (6.3) to the tiles with a suitable high strength adhesive (e.g. epoxide adhesive). After a further 24 h storage under st
32、andard conditions determine the tensile adhesion strength of the adhesive by applying a force increasing at a constant rate of (250 50) N/s. 9 Evaluation and expression of results The individual tensile adhesion strengths are quoted to the nearest 0,1 N/mm2using the following equation: As = L / A wh
33、ere As is the individual tensile adhesion strength in N/mm2; L is the total tensile load in N; A is the bonding area in mm2(2 500 mm2). The tensile adhesion strength for each time interval is determined as follows: determine the mean of the ten values; discard the values falling outside the range of
34、 20 % of the mean value; if five or more values remain, determine the new mean; if less than five values remain repeat the test; determine the mode of failure of the test units according to EN 12004 as the predominant mode. The open time in minutes, is the maximum time interval at which the adhesive
35、 meets the tensile adhesion strength requirement defined in EN 12004.
