22、ions given in EN 26927:1990 apply. 4 Principle This method describes an accelerated test for the assessment of damage of the cold applied sealants arising from the influence of fluctuating temperatures, water-spraying and simultaneous dynamic load. 5 Apparatus and materials 5.1 Concrete test blocks

23、Concrete supports in accordance with EN 13880-12, for the preparation of the test specimens, of dimensions as shown in Figure 1. Two supports are required for each test specimen. 5.2 Tensile/compression test rig Apparatus, which allows specimens to be inserted into holding clamps, conveniently and w

24、ithout disturbing the specimens before, during or after removal shall be used. The apparatus shall be capable of testing a number of test specimens simultaneously and shall not be significantly affected by the failure of one or more specimens. The apparatus shall have the following characteristics:

25、Be motor driven through positive drives without slip or significant backlash, so that cycles of extension and compression are carried out steadily and automatically; EN 14187-9:2006 (E) 5 be capable of moving the test blocks and specimens smoothly and linearly, so that their alignment is maintained

26、at all times without subjecting them to torsion, bending, shock, or significant vibration; be capable of exerting on each specimen an appropriate tensile/compression force and extending the specimen uniformly under the specified conditions according to 7.2 and 7.4; be capable of measuring and record

27、ing the force with an uncertainty of maximum 2 % after application of the force to each system; the tolerance of the movement shall not exceed 0,01 mm. 5.3 Climate chamber Climate chamber shall be capable of reducing the temperature of the specimens to the specified temperature in the range from 30

28、C to 30 C drop/rise throughout the period of examination. The chamber shall be fitted with a time controlled device to allow the specimen to be subjected to spraying with distilled or demineralized water for 20 % of the total conditioning time at the fixed temperatures as provided in 7.4. 5.4 Temper

29、ature indicator The temperature indicator shall consist of an electronic device capable of measuring temperatures in the range of 40 C to 50 C to an accuracy of 1 C. 6 Preparation of the test specimens For each test, at least three test specimens shall be prepared. Prepare the test specimens in acco

30、rdance with the manufacturers instructions including the application of a primer, etc. where stipulated. The test specimens shall be as shown in Figure 1. Prior to conditioning, the gelation time of the sealant shall be determined in the following way. Measure tack free time in accordance with EN 14

31、187-2. Thereafter, prepare test specimens in accordance with EN ISO 7390. After the preparation, place test specimens in standard conditions (23 2) C, (50 5) % r. h.). Examine the first test specimen as described in EN ISO 7390, procedure B after the time equal to the tack free time. If no flow is o

32、bserved, the gelation time is equal to the tack free time. In other cases, the examination shall be repeated in steps of additional 10% of the tack free time until no flow is observed. Prepare the test specimens and immediately after the sealant has gelled carefully mount them in the tensile test ri

Mount the

34、test specimens on a tensile test rig in the climate chamber as shown in Figure 2. Subject the test specimens to the following conditioning cycle shown in Figure 3. Temperature cycling: minimum temperature (10 1) C, maximum temperature (25 1) C. Rate of deformation: (0,010 0,002) mm/min. Movement: Ex

37、3 days, or longer if the manufacturer recommends a longer curing time to have a fully cured sealant. After conditioning, the test specimens shall be subjected to the test procedure in accordance with 7.4. 7.2 After conditioning After completion of the conditioning cycle the temperature shall be lowe

Cut a 3 mm deep notch with a sharp knife 1 mm from the concrete blocks at the short side of the joint. Extend the specimen to 19,2 mm (60 %) and inspect it after 5 min with respect

42、 to further visible damage and fracture such as adhesion- or cohesion-failure. 8 Calculation and expression of results The force at 30 C in each cycle and for each test specimen shall be converted to tensile stress according to the formula: EN 14187-9:2006 (E) 10 AF=(1) where is the tensile stress,
