DIN EN 1109:2013-07 EN 1109:2013 (E) 4 Introduction This European Standard is intended for the characterisation and/or classificatio
20、n of bitumen sheets as manufactured or supplied before use. The test method relates exclusively to products, or to their components where appropriate, and not to waterproofing systems of such products and installed in the works. This test is intended to be used in conjunctions within the relevant Eu
21、ropean products specifications for bitumen flexible sheets for waterproofing. The test for flexibility at a low temperature is intended to determine the susceptibility to cracking of the bituminous coating on a sheet when bent under specified conditions. The test result is dependent on the type of c
22、oating, on the thickness of the sheet, type and position of the reinforcement and the behaviour of the surface material. The use of the test results directly to compare the performance of coatings in sheets of different composition is strictly limited because of the influence of parameters which hav
23、e not been quantified. Only the results from sheets with the same composition can be used to compare the performance directly. The test primarily serves to characterise bitumen sheets. It can be used to evaluate the change in the cold bending behaviour during artificial ageing. It is not safe to rel
24、ate the test results to the actual performance to be expected at low temperatures in service. Compared to EN 1109:1999, in this new version of EN 1109 one type of coolant is described, which will give more reliable results. DIN EN 1109:2013-07 EN 1109:2013 (E) 5 1 Scope This European Standard specif
25、ies the determination of flexibility of bitumen sheets at low temperatures. The test can be carried out on the upper or lower face of the sheet either at a predetermined temperature or successively at different temperature steps to determine the cold bending temperature which represents a limiting t
26、emperature. Therefore, the test can be used to confirm a minimum cold bending temperature for a product or to determine the specific cold bending temperature for the product e.g. to determine the change of these properties as a result of artificial ageing. In the case of sheets with the same bitumin
27、ous compound on both sides and where the reinforcement is placed in the cross section visually closer to the upper surface, the test is performed on the bottom face only. If the upper surface is covered with a non-woven (e.g. tissue, fleece etc.) or metal facing, the test is performed on the bottom
28、side only. If the sheet on the upper surface is covered with permanent light surface protection and where the reinforcement is placed in the cross section visually closer to the upper surface, the test is performed on the bottom side only. 2 Normative references The following documents, in whole or

30、Bitumen, plastic and rubber sheets for roof waterproofing Rules for sampling 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 flexibility ability of bitumen sheet test specimens to be bent under specified conditions without cracking 3.2 cold b
31、ending temperature lowest temperature at which bitumen sheet test specimens can be bent around specified mandrel without cracking 3.3 crack fissure in the coating of the bitumen sheet extending to the reinforcement or completely through unreinforced sheets 4 Principle The test specimens taken from t
32、he test sample are bent through an angle of 180 in a mechanical bending apparatus immersed in a coolant. After bending, the test specimens are examined for the presence of cracks in the coating. DIN EN 1109:2013-07 EN 1109:2013 (E) 6 5 Apparatus The construction and method of operation of the appara
33、tus are shown in Figure 1. The apparatus consists of two non-rotating cylinders (20 0,1) mm in diameter and a cylindrical or semi-cylindrical bending mandrel (30 0,1) mm in diameter, capable of moving upwards and placed between them. The distance a between the cylinders is adjustable so that the dis
34、tance between the cylinders and the bending mandrel can be adjusted to the thickness of the sheet. The bending part of the apparatus is immersed in a thermostatic bath, the temperature of which can be controlled between +20 C and 40 C to the nearest 0,5 C. The coolant used shall be down to -25C: a m
35、ixture of ethylene glycol (CH2OHCH2OH)/water (volume ratio 1:1); below 25 C: a mixture of ethanol/water (volume ratio 2:1). For elastomeric modified bitumen sheets, the mixture of ethanol/water (volume ratio 2:1) can be used at any temperature. To check the test temperature, an additional thermomete
36、r capable of measuring to 0,5 C is required; its thermo sensor shall be placed in the test medium at the same level as the test specimen. To position the test specimens in the test liquid so that they are flat and completely immersed for conditioning, suitable removable holding devices shall be used
37、. The holding devices should be capable of taking at least five test specimens of a series. For the test, the bending mandrel is raised from below against the test specimen at a speed 360 mm/min so that the test specimen is bent through an angle of 180. The electronic control system shall ensure tha
38、t the travel speed is maintained at (360 40) mm/min at each phase of the bending process and at each temperature. Cracks are detected by visual inspection without any optical aids by the person carrying out the test. To permit an accurate assessment, the travel path is defined in such a way that the
39、 test specimen projects out of the coolant at the end of the procedure. The travel section shall be limited by suitably set limit switches. a) Beginning of bending DIN EN 1109:2013-07 EN 1109:2013 (E) 7 b) End of bending Key 1 coolant 2 bending mandrel 3 fixed cylinder 4 thermosensor Figure 1 Princi
40、ple of test apparatus and bending process 6 Sampling Test samples shall be taken in accordance with EN 13416. Rectangular test specimens with dimensions of (140 1) mm (50 1) mm as required by the tests described in 8.3 or 8.4 are taken from the test sample uniformly over the width of the sheet and w
41、ith the larger dimension in the longitudinal direction of the sheet. The test specimens shall not be taken within approximately 150 mm of the edges of the sheet. The test specimens shall be numbered consecutively, beginning from one edge of the sheet, and the lower face of the sheet shall be marked.
42、 7 Preparation of test specimens Any protective film/foil shall be removed, preferably by applying a self adhesive tape to it at ambient temperature, cooling the test specimen to approximately the presumed cold bending temperature and then pulling the adhesive tape from the test specimen. Alternativ
43、ely or additionally, the film can be removed by means of a compressed air jet (maximum pressure approximately 5 bar, nozzle diameter approximately 0,5 mm). It is not permitted to remove the film/foil using heat (e.g. a gas flame). The test specimens shall then be conditioned prior to the test for at
44、 least 4 h at (23 2) C on a flat support so that they do not touch each other. There can be no adhesive connection with the support. Where necessary, a sheet of siliconised paper can be used. Loose surface granules shall be removed before by hand by gentle tapping. 8 Procedure 8.1 Preparation of app
45、aratus Prior to beginning the series of tests, the distance a (see Figure 1) between the cylinders shall be adjusted to the thickness of the test specimen so that it is approximately 32 mm plus twice the thickness of the test specimen. The apparatus is then placed in the refrigerant bath so that the
46、 top of the cylinders is approximately 10 mm beneath the surface of the coolant. The bending mandrel is then in the bottom position. DIN EN 1109:2013-07 EN 1109:2013 (E) 8 8.2 Conditioning of test specimens After the specified test temperature in the coolant has been reached to the nearest 0,5 C, th
47、e test specimens are inserted into the holding device at the height of the cylinders so that coolant freely circulates around them. The test specimens are conditioned for 1 h 5 min in the coolant from the time when the temperature of the coolant is restored. The thermo sensor positioned approximatel
48、y level with the test specimens is used for checking the temperature of the coolant. Then the test specimens are tested as described in 8.3 or 8.4. 8.3 Flexibility at a specified temperature Two series of five test specimens are conditioned as described in 8.2 at the specified test temperature, which is intended to be a whole number. One series will be used for testing the upper face, if applicable, and the other for the lower face. They are tested as follows. The test specimens are place
