16、e This European Standard specifies a procedure for determining the watertightness of polymer modified bituminous thick coatings for waterproofing (i.e. the resistance to hydraulic pressure). 2 Normative references The following referenced documents are indispensable for the application of this docum

17、ent. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. FprEN 15814:2011, Polymer modified bituminous thick coatings for waterproofing Definitions and requirements ISO 554, Standard atmospher

18、es for conditioning and/or testing Specifications 3 Terms and definitions For the purposes of this document, the terms and definitions given in FprEN 15814:2011 apply. 3.1 watertightness the coating can be deemed watertight if the side of the specimen that is not exposed to water does not exhibit an

19、y leakage of water 4 Principle Test procedure for polymer modified bituminous thick coatings intended for use in pressure application, e.g. pressured water in soil. Submission of a test specimen to a specified water pressure for at least 24 h against a disk containing four slots of specified form an

20、d dimensions. The test specimen is observed to establish whether it remains watertight. BS EN 15820:2011EN 15820:2011 (E) 5 5 Apparatus The apparatus consists of a device (see Figures 1 and 2) by which a pressure can be applied to one side of a test specimen.

The form and dimensions of the slots

22、are specified by the requirements indicated in Figure 3. BS EN 15820:2011EN 15820:2011 (E) 6 Dimensions in millimetres Key aall edges of the slotted plate are rounded to a radius of 0,5 mm approximately Figure 3 Slotted plate 6 Test specimens 6.1 General 3 circular test specimen with a diameter equa

23、l to the extend diameter of the slotted plate (approximately 130 mm). 6.2 Preparation Production of a membrane from the polymer modified bituminous thick coatings in accordance with classes defined in FprEN 15814:2011, Table 1. In case reinforcement is used the first layer is placed on a release lay

24、er with approximately half the thickness of the bitumen layer. Subsequently the reinforcement is incorporated and finally the second layer of bitumen is applied. The wet layer has to be that thick, that after drying process the designated dry layer thickness will be achieved. To provide the designat

25、ed dry layer thickness the wet coating has to be levelled off with the help of a frame or gauge of accordant height. 6.3 Conditioning of test specimens The test specimens shall be stored for at least 28 days at a normal climate of (23 2) C and a relative humidity of (50 5) % in accordance with ISO 5

26、54 prior to testing. 6.4 Dimensions of the test specimens The thickness of the dry layer shall be measured using vernier callipers permitting a reading to 0,1 mm. 12 readings shall be taken. The highest and lowest values shall be ignored and the mean value calculated from the remaining 10 values. BS

27、 EN 15820:2011EN 15820:2011 (E) 7 7 Procedure 7.1 Test conditions The test shall be carried out at (23 2) C. The test pressure shall be specified in the product specification. It shall be ensured that the margins are watertight. 7.2 Procedure Fill the apparatus in accordance with Figure 1 with water

28、 until overflowing. Place the test specimen with its upper side downwards in the apparatus and cover with the specified slotted plate. Place the cover and progressively tighten until the specimen is tightly in place. Pressurise progressively to the specified test pressure. Once the test pressure is

29、reached, maintain the pressure for a period according to the product specific but minimum 24 h. Observe the watertightness of the test specimen after the testing time (sudden pressure drop or presence of water on the non exposed face of the test specimen). 8 Expression of results and precision 8.1 E

30、xpression of results The watertightness test is considered passed if all test specimens remain watertight on the side subjected to the test pressure after the specified testing time. 8.2 Precision Precision data are currently not available. 9 Test report The test report shall include at least the fo

31、llowing information: a) all details necessary to identify the product tested; b) a reference to this European Standard (i.e. EN 15820) and any deviation from it; c) details of preparation of test specimens in accordance with Clause 6; d) test procedure including: test pressure; test period; specimen

32、 thickness; deviation of test conditions; BS EN 15820:2011EN 15820:2011 (E) 8 e) the test results in accordance with Clause 8; f) the dates of the tests.
