26、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 Concrete supports in accordance with EN 13880-12, for the preparation of the test specime

27、ns, 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 without disturbing the specimens before, during or after removal shall be used. The appara

28、tus 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: Be motor driven through positive drives without slip or significant backlash, so that cyc

29、les 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 at all times without subjecting them to torsion, bending, shock, or significant vibration

30、; 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 recording the force with an uncertainty of maximum 2 % after application of the force to each s

31、ystem; 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 C to 30 C drop/rise throughout the period of examination. The chamber shall be fitted wit

32、h 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 Temperature indicator The temperature indicator shall consist of an electronic device capable o

33、f 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 accordance with the manufacturers instructions including the application of a primer, etc. wh

34、ere 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 14187-2. Thereafter, prepare test specimens in accordance with EN ISO 7390. After the prepa

35、ration, 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 observed, the gelation time is equal to the tack free time. In other cases, the examinatio

36、n 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 rig.
