26、ature as required. 5.1.2 Procedure Clean the surface of the sag fiow board. Mix the components of the sample in accordance with the manufacturers instructions. With the sag flow board in the horizontal position, spread the sample into each of the required channels, beginning with the shallowest chan
27、nel. Round the material slightly above the top of the guides for each channel. With a straightedge, strike off the excess flush with the top surface of the guides for each channel, and flush with the lower end of the guides (see Figure 2). After all the required channels have been filled, allow the
28、sag board to remain in a horizontal position for a further 30 s. Then, place the board gently into the vertical position, so that the board rests on the edge marked bottom (see Figure i). Start the timer. The board shall remain in position throughout the test. Ali the required channels should be fil
29、led within 10 min after the end of mixing. If the open time of the mixture, as measured by prEN 12189 is less than 15 min, the material should be tested in channels one at a time. At the end of the test (30 min unless otherwise reported), measure in miliietres the distance from the lower end of the
30、guides to the point of maximum flow for each thickness of interest. If the adhesive reaches the base of the sag flow board, the report should state that the sag was greater than 50 nun. 5.2 Squeezability test 5.2.1 Conditioning Condition the resin and hardener components of the bonding agent as well
31、 as the plates for at least 4 h at the test temperature of (21 * 2) “C or an alteniative temperature as required. 5.2.2 Procedure Mix the components of the sample in accordance with the manufacturers instructions. 10 min after the completion of mixing, pour 300 cm3 of bonding agent onto a sheet of w
32、ax paper, placed on a hard level surface. The area occupied by the bonding agent should be as small as possible. Place a second piece of wax paper over the poured out bonding agent. A flat piate is placed on top of this second wax paper and a load of 150 N is applied centrally and vertically The fla
33、t plate should be maintained parallel with the level surface. Maintain this load for 3 min, then remove the load and steel plate and measure the squeezed out diameter of the bonding agent. If the material squeezes out beyond the test area, the quantity of material should be reduced as appropriate. O
