21、41 Scope This European Standard specifies a test method for the determination of water absorption in waterproofing sheets which could influence the functional behaviour of these sheets. NOTE It is primarily the reinforcements ability to absorb water which is examined by this test. 2 Normative refere

25、- Definitions and characteristics ISO 5725-2, Accuracy (trueness and precision) of measurement methods and results Part 2: Basic method for the determination of repeatability and reproducibility of a standard measurement method 3 Terms and definitions For the purposes of this document, the terms and
26、 definitions given in EN 13416, EN 14695, prEN 17048 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 waterproofing sheet is measured after the test specimen has
27、been immersed in water for a defined period and determined as the increase in mass of the test specimen. 4.2 Apparatus and materials 4.2.1 Balance, capable of measurements to the nearest 0,1 g. 4.2.2 Water bath, capable of maintaining a temperature of (23 3) C. 4.2.3 Chamber (or laboratory), capable
28、 of maintaining a temperature of (23 3) C and (50 5) % RH. 4.2.4 Distilled water, or de-ionized water. 4.2.5 Equipment for hanging test specimens, without damaging the specimens. DIN EN 14223:2017-07 EN 14223:2017 (E) 54.2.6 Steel wire brush, medium hard. 4.2.7 Oven with circulating air, (without fr
29、esh air supply) and capable of maintaining a temperature of (50 3) C. 4.3 Preparation of test specimens Take 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 dime
30、nsions of (200 1) mm (200 1) mm shall be prepared for testing. If the reinforced waterproofing sheet has a surfacing of fine mineral or granules, the surface shall be brushed gently with a steel wire brush to remove any loose mineral or granule. A protective film on the bottom side should be removed
31、 as described in EN 1109. 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 surfacing. The test specimen area shall be the same as described above. 4.4 Drying and conditioning of the test speci
32、mens 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 placed hanging vertically with a space of at least 20 mm between test specimens. 4.5 Procedure 4.5.1 Weigh th
33、e 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 specimens. The entire area of the test specimen shall be covered with water during the entire test period. 4.5.2
34、 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 space of at least 20 mm between the test specimens. The set of five test specimens shall be placed in the labora
35、tory 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 test specimen (expressed as a percentage by mass) shall be calculated using Formula (1) 100112mmmw= (1) where:
36、 m1is 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 value of the five test specimens shall be calculated and recorded. DIN EN 14223:2017-07 EN 14223:2017 (E) 6 4.6.2 P
37、recision The repeatability r and the reproducibility R is determined by: 0,0995 0,0766rw= + (2) 0,154 0,1048Rw= + (3) 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.
38、NOTE 1 Precision data are based on a ring test performed in accordance with ISO 5725-2 for water absorption values between 0,2 % and 5,1 % by mass. NOTE 2 The precision data have only been found for bitumen sheets. 4.7 Test report The test report shall include at least the following information: a)
39、all details necessary to identify the product tested; b) reference to this European Standard and any deviation from 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.
