23、ndard describes a method for the determination of the suitability of structural bonding agents applied using a spreader to a vertical or horizontal surface, referred to as the “sag flow test”. This standard also describes a method for the determination of the suitability of injectable structural bon

24、ding agents for application between two surfaces, referred to as the “squeezability test”. 4 Equipment 4.1 Sag flow test 4.1.1 Sag flow board, in steel as depicted in Figure 1. 4.1.2 Temperature-controlled conditioning cabinet, adjustable to within 18C. 4.1.3 Thermometer measuring in degrees Celsius

25、 with 0,18C divisions. 4.1.4 Straightedge. 4.1.5 Timer. 4.1.6 Mould release agent. 4.2 Squeezability test 4.2.1 Wax papers, at least 400 mm square. 4.2.2 Flat steel plate, 6 mm thick and at least 400 mm square. 4.2.3 Means of applying load of 150 N. 4.2.4 Timer. 4.2.5 Rule, graduated in mm. 5 Test p

26、rocedure 5.1 Sag flow test 5.1.1 Conditioning Condition the resin and hardener components of the bonding agent and the sag flow board for at least 4 h at the test temperature of (21 2)8C or an alternative test temperature as required. 5.1.2 Procedure Clean the surface of the sag flow board. Mix the

27、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 channel. Round the material slightly above the top of the guides for each channel. With

28、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 sag board to remain in a horizontal position for a further 30 s. Then, place the boa

29、rd gently into the vertical position, so that the board rests on the edge marked bottom (see Figure 1). Start the timer. The board shall remain in position throughout the test. All the required channels should be filled within 10 min after the end of mixing. If the open time of the mixture, as measu

30、red 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 millimetres the distance from the lower end of the guides to the point of maximum flow for each thickness of interest. If the adhesive

31、 reaches the base of the sag flow board, the report should state that the sag was greater than 50 mm. 5.2 Squeezability test 5.2.1 Conditioning Condition the resin and hardener components of the bonding agent as well as the plates for at least 4 h at the test temperature of (21 2)8C or an alternativ

32、e 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 cm 3 of bonding agent onto a sheet of wax paper, placed on a hard level surface. The area occupied by the bonding agent shoul

33、d be as small as possible. Place a second piece of wax paper over the poured out bonding agent. A flat plate is placed on top of this second wax paper and a load of 150 N is applied centrally and vertically. The flat plate should be maintained parallel with the level surface. Maintain this load for

34、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.Page 4 EN 1799:1998 BSI 06-1999 6 Test report 6.1 Sag flow test The report shall includ
