26、d automatically; capable of moving blocks smoothly and linearly, so that their alignment is maintained at all times and the test specimens are not subjected to torsion, bending, shocks or significant vibration; capable of exerting on each test specimen a tensile force of up to 2 500 N and subject to

27、 such a force being sufficient, extending each test specimen uniformly under all conditions by (18,00 0,25) mm at a rate of (6,00 0,25) mm/h; capable of exerting on each extended test specimen a compressive force of 2 500 N in order to compress each test specimen uniformly under all conditions to it

28、s original length.The accuracy of the test rig shall be class 2A according to ISO 5893.If the apparatus is capable of testing a number of test specimens simultaneously, it shall not be significantly affected by the premature failure of one or more test specimens.5.3 Cooling chamberCooling chamber ca

29、pable of reducing the temperature of a full set of test specimens to the appropriate test temperature in not more than 4 h and holding the test specimens at this temperature for at least 36 h. The test temperature is according to EN 141881.The chamber shall be fitted with a calibrated temperature in

30、dicator accurate to 1,0 C with its bulb or sensor at the point where the temperature fluctuation is known to be greatest. Alternatively, the temperature indicator may be placed in the centre of the horizontal plane above the top of the specimens.5.4 Measurement of forcesOne or more devices for measu

31、rement of forces, fitted at the outside of the cooling chamber, measuring the tensile forces applied to each test specimen.5.5 RulerRuler or other suitable device to measure depth and width of defects to the nearest 1mm.6 Preparation and conditioning of test specimens6.1 Prepare the test sample acco

See Figure 1.Key1 joint sealant2 concrete blockFigure 1 Test Sample (dimensions in mm)6.4 If a primer is used,

34、apply it to the sawn test faces of the concrete test blocks in accordance with the manufacturers instructions.6.5 Place a top-mask on the jig so that the joint can be overfilled when the hot applied joint sealant in poured into it.6.6 Any adhering of the poured hot applied joint sealant to the borde

35、rs of the joint shall be avoided.6.7 Allow the test specimens to cool at laboratory temperature for 2 h after which remove the excess hot applied joint sealant using a heated knife so that the test specimens are flush with the surface of the concrete test blocks.6.8 Three test specimens shall be pre

36、pared for each test.7 Procedure7.1 Carefully transfer the test specimens to the tensile rig. Make sure they are tightly fixed to the driving mechanism both in tensile and compression.6 BS EN 1388010:2018EN 1388010:2018 (E)7.2 Reduce the temperature of the atmosphere surrounding the test specimen and

37、 maintain that temperature for a period of at least 6 h and during the test.NOTE The relevant testing temperatures for hot applied joint sealants are in accordance with EN 141881.7.3 The test specimens are subjected to two and a half cycles of extension and compression as follows:Extend the joint to

38、 the maximum defined extension at a uniform rate of (6,00 0,25) mm/h and immediately compress the test specimen at the same uniform rate and at the same temperature to its original dimension without removal from the test rig.7.4 The temperature of the air around the specimens, the forces and the ext

39、ension shall be recorded during the entire test procedure. The extension can be measured outside the chamber as long as the accuracy requirement is fulfilled for the sealant specimens. The forces shall be measured outside the chamber.7.5 Record the maximum force reached for each test specimen.7.6 Ex
