BS EN 15816:2011EN 15816:2011 (E) 4 1 Scope This European Standard specifies a proced
16、ure for determining the resistance to rain of polymer modified bituminous thick coatings for waterproofing. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references,
17、the latest edition of the referenced document (including any amendments) applies. EN 206-1, Concrete Part 1: Specification, performance, production and conformity FprEN 15814:2011, Polymer modified bituminous thick coatings for waterproofing Definitions and requirements ISO 228-1, Pipe threads where
18、 pressure-tight joints are not made on the threads Part 1: Dimensions, tolerances and designation ISO 554, Standard atmospheres 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 and the follow
19、ing apply. 3.1 resistance to rain resistance of the polymer modified bituminous thick coatings to the damaging effects of exposure to rain 4 Principle The test provides an indication of the resistance of a freshly applied polymer modified bituminous thick coating to rain. The time after which a coat
20、ing layer can be said to be resistant to rain under the conditions prevailing on the building site can vary quite considerably from the time determined in the laboratory. The measured values are therefore primarily suitable for use to compare the resistance of different products to rain. 5 Apparatus
21、 5.1 Sprinkler (see Figure 1) Standard conical nozzle made of copper-zinc alloy, pipe thread to ISO 228-1 G1/4B, sprinkler cone 85, flow rate 9l/min at 3 bar operating pressure; commercial pressure regulator with pressure gauge to indicate test pressure of (2 0,1) bar; specimen holder to position th
22、e specimen at an angle of 45 to the sprinkling plane. 5.2 Nozzle holder to position the nozzle; the nozzle shall be placed such that the vertical distance between the nozzle and the centre of the surface of the specimen is 25 cm. 5.3 Connection to water mains, hoses, connectors. 5.4 Stop watch BS EN

26、ing of test specimens After coating, the specimens shall be left to stand for a period of time specified by the manufacturer, but not longer than 8 h in a normal climate of (23 2) C and a relative humidity of (50 5) % in accordance with ISO 554. 7 Procedure 7.1 Test conditions The test shall be carr
27、ied out at (25 5) C. 7.2 Procedure The specimens shall be tested after conditioning. Prior to the test the water pressure shall be set at (2 0,1) bar when the water is running. Measure the temperature of the water. Two specimens shall be tested either simultaneously in two test rigs or one immediate
28、ly after the other in the same test rig. Place the specimen(s) in the holder under running water and start the stop watch. The test shall last 15 min. During the test, the water running off the test specimens shall be assessed for discolouration. If necessary, repeat the test using different specime
29、ns. 8 Expression of results and precision 8.1 Expression of results The water running off the test specimens shall not be discoloured during the test and the coating shall not deteriorate (e.g. surface erosion, water trapped in the material). In the event of such deterioration the test shall be repe
30、ated with a longer conditioning period on other specimens until at least two samples pass the test. The test result shall be the shortest conditioning period in which two samples produce no discolouration, stated to 0,5 h. This is the time in which a layer of freshly applied polymer modified bitumin
31、ous thick coating can be described as resistant to rain as defined in this test specification. The period shall not exceed 8 h. 8.2 Precision Precision data are currently not available. 9 Test report The test report shall include at least the following information: a) a reference to this European St
32、andard (i.e. EN 15816); b) all details necessary to identify the product tested; c) test procedure including any deviations from the test conditions; BS EN 15816:2011EN 15816:2011 (E) 7 d) the test results in accordance with Clause 8; e) the date of the tests.
