The machine shall be ca
27、pable of applying the load to the pull-head plate at the rate of (250 50) N/s through a suitable fitting that does not exert any bending force. 6.4 Air-circulating oven An air-circulating oven capable of controlling the temperature to within 3 C. 6.5 Notched trowel A notched trowel having 6 mm 6 mm
28、notches at 12 mm centres. 7 Mixing of the adhesive The amount of water and/or liquid admix, required for preparing the adhesive, shall be as stated by the manufacturer in parts by mass (e.g. the amount of liquid, in kilos and the amount of powder, in kilos, to be mixed, shall be declared). If a rang
29、e of values is given, the average shall be used. A minimum quantity of 2 kg of the adhesive shall be prepared in a mixer of the type described in 4.4 of EN 196-1:2005, using the slow speed settings (140 5) r/min and (62 5) r/min planetary movement. Carry out the following procedure: pour the liquid
30、into the pan; scatter the dry powder over the liquid; mix for 30 s; Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 28/02/2008 06:39, Uncontrolled Copy, (c) BSIEN 1348:2007 (E) 6 take out the mixing paddle; scrape down the paddle and pan within 1 min; replace the paddle and mix for 1 min. Let
31、 the adhesive mature in accordance with the adhesive manufacturers instructions, followed by further mixing for 15 s. 8 Procedure 8.1 Preparation of test units Apply a thin layer of the adhesive, mixed in accordance with Clause 7, to the concrete slab with a straight edge trowel. Then apply a thicke
32、r layer and comb with a notched trowel (6.5). The trowel shall be held 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 place ten type V1 tiles on the adhesive at a distance apa
33、rt of 50 mm and load each tile with (20 0,05) N for 30 s. 8.2 Initial adhesion strength Prepare the test units in accordance with 8.1. After 27 days storage under standard conditions bond the pull-head plates (see 6.2) to the tiles with a suitably high strength adhesive (e.g. epoxide). After a furth
34、er 24 h storage under standard conditions determine the tensile adhesion strength of the adhesive by applying a force at a constant rate of (250 + 50) N/s. If fast-setting properties of adhesives are to be tested, also determine the tensile adhesion strength 6 h after bonding, under standard conditi
35、ons (see Clause 4). Report the results in Newtons. 8.3 Tensile adhesion strength after water immersion Prepare the test units in accordance with 8.1. Condition the test units under standard conditions for 7 days, and immerse in water at the standard temperature. After 20 days remove the test units f
36、rom the water, wipe with a cloth and bond the pull-head plates (6.2) to the tiles. After a further 7 h immerse the test units in water at the standard temperature. The following day remove the test units from water and immediately carry out the tensile adhesion test in accordance with 8.2. Report th
37、e results in Newtons.

Condition the test units under standard conditions for 14 days an
38、d then place the units in an air-circulating oven at (70 3) C for a further 14 days. Remove from the oven and bond the pull-head plates (6.2) to the tiles with a suitable high strength adhesive (e.g. epoxide). Condition the test units for a further 24 h under standard conditions. Determine the tensi
39、le adhesion strength in accordance with 8.2. Report the results in Newtons. 8.5 Tension adhesion strength after freeze-thaw cycle Prepare the test units in accordance with 8.1. In addition a layer of the adhesive approximately 1 mm thick shall be applied with a straight edged trowel to the back face
40、 of the type V1 tile before placing. Condition the test units for 7 days under standard conditions and immerse in water for 21 days before carrying out 25 freeze-thaw cycles. For each freeze-thaw cycle: 1) remove the test units from the water and and place in a cold chamber to achieve a steady cabin
41、et temperature of (-15 3) C within 2 h 20 min; 2) maintain the test units at (-15 3) C for 2 h 20 min; 3) immerse the test units in water at (20 3) C and raise the temperature to (15 3) C; 4) maintain the test units at (15 3) C for a minimum 2 h before commencing the next freeze-thaw cycle. Repeat t
42、he cycle 25 times. After the last cycle remove the test units from water, wipe with a cloth and bond the pull-head plates (6.2) to the tiles. Condition the test units for a further 24 h under standard conditions and determine the tensile adhesion strength in accordance with 8.2. Report the results i
43、n Newtons. 9 Evaluation and expression of results The individual tensile adhesion strength shall be determined to an accuracy of 0,1 N/mm2using the following equation: As= L / A where Asis the individual tensile adhesion strength in Newtons per square millimetre; L is the total load in Newtons; A is
44、 the bonding area in square millimetres (2 500 mm2). The tensile adhesion strength for each set of conditions shall be determined as follows: Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 28/02/2008 06:39, Uncontrolled Copy, (c) BSIEN 1348:2007 (E) 8 determine the mean of the ten values; di
45、scard the values falling outside the range of 20 % from the mean value; if five or more than five values remain, determine the new mean value; 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. 10 Test repo
