16、:2011 (E) 4 1 Scope This European Standard specifies a procedure for determining the reduction in the thickness of polymer modified bituminous thick coatings due to drying for waterproofing. 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. EN 1426, Bitumen and bituminous binders Determination of needle penetration FprEN 15814:2011, Polymer modified bituminous thick coating
18、s for waterproofing Definitions and requirements 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 apply. 4 Principle The reduction of thickness of polymer modifi
19、ed bitumen emulsion is the difference between measuring of wet and dry layer thickness under special conditions on a coated surface. 5 Apparatus 5.1 Stiff metal or glass plate with the following minimum dimensions: 25 cm 25 cm. 5.2 Plastic or metal frame with a height of 5 mm and inside dimensions o
20、f 15 cm 20 cm. 5.3 Palette knife, smoothing trowel, mixing equipment. 5.4 Instrument for measuring the thickness of the wet layer, e.g. penetrometer as described in EN 1426. 5.5 Suitable instrument for measuring the thickness of the dry layer, e.g. sliding calliper or inductive measuring instrument.
21、 6 Test specimens Test specimen with dimensions of 200 mm 150 mm 5 mm. BS EN 15819:2011EN 15819:2011 (E) 5 7 Preparation The ready-to-use bitumen coating shall be prepared in accordance with the manufacturers instructions. In case of a two component emulsion, mix the bitumen emulsion (component A) a
22、nd cement (component B), using a low-speed mixer setting to avoid entrapping any air. Fasten the frame to the degreased metal or glass plate and place it on a horizontal surface. Fill the frame up to the top with the mixed coating, taking care not to entrap any air. Strike off the top of the coating
23、 with the smoothing trowel so that it is level with the top of the frame. 8 Procedure 8.1 Test conditions The test shall be carried out at a temperature of (23 2) C. 8.2 Procedure Determine the thickness of the wet layer immediately after preparation of the specimens. NOTE A penetrometer as describe
24、d in EN 1426 is suitable for this purpose. The frame shall remain in place to prevent the fresh specimen spreading outwards. Measure the wet thickness to 0,1 mm at five equally spaced points in each third of the specimen but at a distance of not less than around 1 cm from the edges. Clean the test i
25、nstrument (e.g. the point of the needle of the penetrometer) prior to each measurement to avoid measuring errors. The thickness of the wet layer (dna) is the mean value of the 15 results, rounded to 0,1 mm. After the thickness of the wet layer has been measured, carefully remove the frame and store
26、the specimen in a horizontal position in a normal climate of (23 2) C and a relative humidity of (50 5) % in accordance with ISO 554 for 28 days (dtr). ()100/natrnaD= ddd % After conditioning, measure the dry thickness of the layer. The thickness of the dry layer shall be measured using vernier call
27、ipers 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. 9 Expression of results and precision 9.1 Expression of results The test result is the reduction in the thickness of the layer
28、(D) in relation to the thickness of the wet layer, expressed as a percentage. 9.2 Precision Precision data are currently not available. BS EN 15819:2011EN 15819:2011 (E) 6 10 Test report The test report shall include at least the following information: a) all details necessary to identify the produc
29、t tested; b) a reference to this European Standard (i.e. EN 15819) and any deviation from it; c) details of preparation of test specimens in accordance with Clause 7; d) test procedure including: specimen thickness (wet/dry and reduction in %); deviation of test conditions; e) the test results in ac
