NOTE

22、 It is primarily the reinforcements ability to absorb water which is examined by this test. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the lat

23、est edition of the referenced document (including any amendments) applies.

25、 definitions For the purposes of this European Standard, the terms and definitions given in EN 13416, prEN 14695 and the following apply. 3.1 water absorption increase in mass of test specimen after immersion in water expressed as a percentage 4 Test method 4.1 Principle The water absorption of the

26、reinforced bitumen sheet is measured after the test specimen has been immersed in water for a defined period and determined as the increase in mass of the test specimen. 4.2 Apparatus and materials a) Balance, capable of measurements to the nearest 0,1 g. b) Water bath, capable of maintaining a temp

27、erature of (23 3) C. c) Chamber (or laboratory), capable of maintaining a temperature of (23 3) C and (50 5) % RH. d) Distilled water, or de-ionized water. e) Equipment for hanging test specimens, without damaging the specimens. f) Steel wire brush, medium hard.

29、ke samples in accordance with EN 13416. The test specimens shall be taken at random and at least 1 m from the end of the roll and 100 mm from the edge of the sheet. Five test specimens with dimensions of (200 1) mm x (200 1) mm shall be prepared for testing. If the reinforced bitumen sheet has a sur

30、facing of fine mineral or granules, the surface shall be brushed gently with a steel wire brush to remove any loose mineral or granule. Should problems with heterogeneous results occur (4.6.2) due to surfacing of fine mineral or granules, test specimens may be taken from parts free from such surfaci

31、ng. The test specimen area shall be the same as described above. 4.4 Drying and conditioning of the test specimens Dry the test specimens for 24 h 30 min at (50 3)C and then condition them for 1 h 5 min at (23 3)C and (50 5) % RH before testing. During drying and conditioning the test specimens are

32、placed hanging vertically with a space of at least 20 mm between test specimens. 4.5 Procedure 4.5.1 Weigh the test specimen (m1) and then immerse it in water for 28 days 4 h at (23 3)C. The test specimen shall be placed hanging vertically in the water with a space of at least 20 mm between test spe

33、cimens. The entire area of the test specimen shall be covered with water during the entire test period. 4.5.2 After the 28 days of immersion in water, air dry the test specimen for 5 h 5 min at (23 3)C and (50 5) % RH. During air drying the test specimen shall be placed hanging vertically with a spa

34、ce of at least 20 mm between the test specimens. The set of five test specimens shall be placed in the laboratory with a free space of air surrounding it (at least 0.5 m on each side). 4.5.3 Reweigh the test specimen (m2). 4.6 Expression of results 4.6.1 Calculation The water absorption w for each t

35、est specimen (expressed as a percentage by mass) shall be calculated using equation (1) 211100mmwm= (1) where: m1 is the mass of the test specimen after drying and conditioning; m2is the mass of the test specimen after immersion in water for 28 days and drying for 5 h. The water absorption mean valu

36、e of the five test specimens shall be calculated and recorded.

37、roducibility R is determined by: r = 0,0995w + 0,0766 R = 0,154w + 0,1048 where w is the water absorption, in % by mass. Based on the given repeatability, the test shall be repeated if the difference between wmaxand wminis higher than 0,3098wmean+ 0,2385. NOTE Precision data are based on a ring test

38、 performed in accordance with ISO 5725-2 for water absorption values between 0,2 % and 5,1 % by mass. 4.7 Test report The test report shall include at least the following information: a) all details necessary to identify the product tested; b) reference to this European Standard and any deviation fr

39、om it; c) information about sampling, preparation, drying and conditioning of test specimens in accordance with 4.3 and 4.4; d) information about the procedure in accordance with 4.5; e) test results in accordance with 4.6; f) date of tests.
