22、alues is given, the average shall be used). Using a minimum quantity of 2 kg of the powder and the recommended quantity of liquid, prepare the adhesive in a planetary mixer using the following slow speed settings: (140 5) rotations per minute and (62 5) rotations per minute planetary movement. See F
23、igures 1 and 2. Carry out the following procedure. 1) Pour the liquid into the pan. 2) Scatter the dry powder over the liquid. 3) Mix for 30 s. 4) Take out the mixing paddle. 5) Scrape down the paddle and pan within 1 min. 6) Replace the paddle and mix for 1 min. If required by the adhesive manufact
24、urers instructions, let the adhesive mature as specified and then mix for an additional 15 s. 3.4.2 Dispersion adhesive (D) and reaction resin adhesive (R) Where ready-to-use dispersion adhesives or reaction resin adhesives are to be used, the manufacturers instructions shall be followed.2 ISO 2013
25、All rights reserved ISO 13007-2:2013(E) 3.5 Test substrate 3.5.1 Concrete test substrate The mandatory concrete test substrate shall be (40 5) mm thick, have a moisture content of less than 3 % by mass, and have a surface water absorption in the range of 0,5 cm 3to 1,5 cm 3after 4 h of testing. The
26、cohesive strength as referenced in A.3.3 shall be at least 1,5 N/mm 2 . A method for manufacturing a suitable concrete test slab and the procedures for measuring the cohesive strength and surface water absorption is given in informative Annex A. 3.5.2 Other substrates Other substrates may be used up
27、on agreement if the substrate is recommended for ceramic tile application by the adhesive manufacturer. To demonstrate compatibility with other optional substrates, the adhesive shall be applied to the selected substrate in accordance with the open time test method (see 4.1). When a result of 0,5 N/
28、mm 2is achieved or cohesive failure occurs in the substrate, the requirement is considered satisfied. 3.6 Failure patterns 3.6.1 Adhesion failure (AF-S or AF-T) Failure occurs at the interface between the adhesive and the substrate (AF-S) see Figure 3, a) or bet ween the tile and the adhesive (AF-T)
29、 see Figure 3, b). The test value is equal to the adhesive strength. In some cases, failure may occur in the adhesive layer between the tile and the pull-head plate (BF) see Figure 3, c). In this case, the adhesive strength is greater than the test value and the test should be repeated. 3.6.2 Cohesi
30、ve failure within the adhesive (CF-A) Failure occurs within the adhesive layer see Figure 3, d). 3.6.3 Cohesive failure in the substrate or in the tile (CF-S or CF-T) Failure occurs within the substrate (CF-S) see Figure 3, e) or within the body of the tile (CF-T) see Figure 3, f). In this case, the
31、 strength of the adhesive is greater than the test value. The modes of failure may be a combination of any of the above. An approximate percentage of each shall be recorded. 3.7 Test report 3.7.1 General The test report shall specify the following: a) a reference to this part of ISO 13007 (i.e. ISO
32、13007-2:2013); b) the date of test; c) the type of adhesive, commercial designation, and manufacturers name; d) the source, date obtained, and complete identification of test sample; e) the handling and storage of samples before testing; f) the test conditions; g) the amount of water or liquid used

39、2013(E) 4.1.4 Procedure Apply a thin layer of the adhesive, mixed in accordance with 3.4.1, to the concrete slab using a straight edge trowel. Then, apply a thicker layer and comb using a notched trowel having 6 mm 6 mm notches at 12 mm centres. The trowel shall be held at an angle of approximately
40、60 to the substrate at a right angle to one edge of the slab and shall be drawn across the slab parallel to that edge (in a straight line). After 5 min, 10 min, 20 min, 30 min, or longer, place at least 10 test tiles 50 mm apart on the adhesive within 30 s. Tiles are placed on no more than four ribs
41、 for all adhesives. Load each tile with (20 0,05) N for 30 s. After storing for 27 d under standard conditions, bond the pull-head plates to the tiles with a suitable high-strength adhesive (e.g. epoxy adhesive). After a further 24 h storage under standard conditions, determine the tensile adhesion
42、strength of the adhesive by applying a force increasing at a constant rate of (250 50) N/s. 4.1.5 Evaluation and expression of results The individual tensile adhesion strengths are quoted to 0,1 N/mm 2using Formula (1): s (1) where A s is the individual tensile adhesion strength, in N/mm 2 ; L is th
43、e total tensile load, in N; A is the bonding area, in mm 2(2 500 mm 2 ). The tensile adhesion strength for each time interval is determined as follows. 1) Determine the mean of the 10 values. 2) Discard the values falling out of the range of 20 % of the mean value. 3) If five or more values remain,
44、determine the new mean. 4) If less than five values remain, repeat the test. 5) Determine the mode of failure of the test units (see 3.6). The open time, in minutes, is the maximum time interval at which the adhesive meets the tensile adhesion strength requirement defined in ISO 13007-1 for open tim
