BS EN 1110:2010EN 1110:2010 (E) 4 Introduction This European Standard is intended for ch
17、aracterisation and/or classification of bitumen sheets as manufactured or supplied for use. The test method relates exclusively to products or to their components where appropriate, and not to waterproofing membrane systems composed of such products and installed in the works. This test method is in
18、tended to be used in conjunction with EN 13707. This test is used to determine the flow resistance of the coating or to determine the flow resistance limit of a bitumen sheet. The test result depends on the type of coating, the sheet thickness, type and position of the reinforcement and type and mas
19、s of the granules on the surface. The use of test results to directly compare the performance of the coating in sheets of different composition is strictly limited because of the influence of other parameters which have not been quantified. Results from sheets with the same composition can be used t
20、o compare the performance of the coating directly. The test primarily serves to characterize bitumen sheets. It can also be used to evaluate the change in flow resistance limit as a result of artificial ageing. It is not recommended to correlate the test results directly to the actual performance ex
21、pected at elevated temperatures in service. BS EN 1110:2010EN 1110:2010 (E) 5 1 Scope This European Standard specifies the determination of flow resistance of bitumen sheets at elevated temperature. The test is carried out at a specified temperature or consecutively at different temperatures in orde
22、r to determine the flow resistance limit. Therefore, the test can be used to provide proof of the flow resistance required for a product or to determine the flow resistance limit specific to the product e.g. in order to establish the change in this behaviour as a result of artificial ageing. The tes
23、t is not applicable to bitumen sheets without reinforcement. 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, the latest edition of the referenced document (
24、including any amendments) applies. EN 13416, Flexible sheets for waterproofing 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 flow resistance ability of bitumen she
25、et test specimen to be suspended vertically under specified temperature conditions without the coating moving by more than 2 mm and no occurrence of falling droplets 3.2 flow resistance limit F highest temperature where less than 2 mm displacement of the coating of a vertically suspended bitumen she
26、et test specimen is measured and no falling droplets from the coating of the test specimen are observed 3.3 flow maximum difference between the longitudinal dimension of the test specimen before and after heating within the oven 3.4 falling droplets oily constituents emitted from the coating of the
27、sheet, which are observed after heating, on a white piece of paper placed under the test specimen during the heating within the oven NOTE Mineral particles (e.g. slate, sand, talcum) are not a part of the coating and should therefore not be assessed as falling droplets. 4 Principle Test specimens ta
28、ken from the test sample are suspended vertically in an oven at a specified temperature. The maximum longitudinal dimensions of the test specimen are measured before and after being heated in the oven. The displacement is calculated as the difference between the longitudinal dimension over the full
29、width of the test specimen, before and after being heated within the oven. Failure is defined as a difference greater than 2,0 mm and/or the occurrence of droplets. BS EN 1110:2010EN 1110:2010 (E) 6 5 Apparatus 5.1 Oven with forced air circulating (without fresh air supply) and a maximum temperature
30、 deviation of 2 C in the test area. After the door has been opened for 30 s, the recovery period to attain the working temperature again shall not exceed 5 min. 5.2 Thin metal wire, S-shaped 5.3 Siliconized paper 5.4 Caliper with an accuracy of 0,1 mm 5.5 White coloured paper able to resist the test
31、ing temperatures 6 Sampling Test samples shall be taken in accordance with EN 13416. Rectangular test specimens with the following dimensions: length X0(100 1) mm, width 50 mm to 100 mm, as required by the tests described in 8.2 or 8.3, are taken from the test sample uniformly over the width of the
32、sheet and with the larger dimension in the transversal direction of the sheet. The test specimens shall not be taken within 150 mm of the edges of the sheet. The test specimens shall be numbered consecutively, beginning from one edge of the sheet. NOTE For practical reasons the minimum width and max
33、imum width are defined. This accommodates the common practise. Lower dimensions than 50 mm could possibly influence the test result and are impractical. Larger dimensions than 100 mm could result in bending of the test specimen during testing which could possibly influence the result. 7 Preparation
34、of test specimens Any protective film shall be removed, preferably by applying a strip of adhesive tape to it at ambient temperature, cooling the test specimen to e.g. the presumed cold bending temperature and then pulling the adhesive tape from the test specimen. Alternatively, or additionally the
35、film can be removed by means of a compressed air jet (maximum pressure approximately 0,5 MPa, nozzle diameter approximately 0,5 mm). The test specimens are then conditioned prior to the test for at least 2 h at (23 2) C on a flat surface so that they do not touch each other and not to stick to the s
36、urface. If necessary, a separating sheet of siliconized paper shall be used to prevent sticking. 8 Procedure 8.1 Preparation for test The oven is preheated to the specified test temperature. For the duration of the test the temperature shall not vary by more than 2 C inside the test area. BS EN 1110
37、:2010EN 1110:2010 (E) 7 8.2 Determination of flow resistance at a specified temperature The three test specimens are provided with a thin S-shaped metal wire fixed in the middle of the short side of the test specimen and at a distance of approximately 15 mm from the top edge. The length X0of each te
38、st specimen is measured. The prepared test specimens are suspended vertically at the same height in the oven with at least 30 mm distance between them. A white coloured piece of paper is placed underneath the test specimens. The time for placing the test specimens and paper in the oven shall not exc
39、eed 30 s. The heating period is (120 2) min after inserting the test specimens. As soon as the heating period is completed, the test specimens shall be removed from the oven without contacting each other and allowed to cool for at least 2 h at (23 2) C in a horizontal position. Measure after the hea
40、ting and cooling period over the whole width of the three test specimens if the longitudinal dimension (from top to bottom) is less or equal to (X0+ 2) mm (see Figure 1). Observe on the white coloured paper the occurrence of any droplet coming from the test specimen. 8.3 Determination of flow resist
41、ance limit The flow resistance limit shall be determined by means of preliminary tests on individual test specimens at different temperatures at intervals of 5 C. The purpose of these preliminary tests is to find two temperature steps T and (T + 5) C within which the following conditions are reached
42、: the displacement dimension L 2 mm and no droplets at temperature T and the displacement dimension L 2 mm and/or occurrence of droplets at temperature (T + 5) C. A new test specimen shall be used for each temperature step. After these two temperatures have been determined in the preliminary test th
43、e flow properties are determined in accordance with 8.2 on a series of three test specimen. The tests are carried out at the two temperatures T and (T + 5) C. A new series of test specimen shall be used for each temperature. 9 Calculation of results, evaluation and precision of test method 9.1 Flow
44、resistance The flow resistance at a specified temperature is regarded as having passed the test, if the longitudinal dimension of the three test specimens from the top to the bottom over the full width does not exceed (X0+ 2) mm and no falling droplets have been observed. 9.2 Flow resistance limit T
45、he flow resistance limit (F) is determined and given to the lowest temperature (T). 9.3 Precision of test method 9.3.1 General The precision of the test method was verified by an interlaboratory test on an APP modified polyester reinforced sheet and on a SBS modified polyester reinforced sheet. Base
46、d on the results of this inter laboratory test CEN/TC 254/SC 1 concluded that the precision of this test method is equal or better than the EN 1110:1999 test method. Therefore, the precision values of the EN 1110:1999, which were determined by BS EN 1110:2010EN 1110:2010 (E) 8 an initial internation
47、al interlaboratory test following ISO 5725:1986, are maintained within this standard. These precision values relate to sheets with polyester reinforcement. 9.3.2 Repeatability Repeatability standard deviation of results: r= 0,7 C Confidence interval (95 %) of a result: qr= 1,3 C Repeatability limit
48、(difference between two results): r = 2 C 9.3.3 Reproducibility Reproducibility standard deviation of results: R= 3,5 C Confidence interval (95 %) of a result: qR= 6,7 C Reproducibility limit (difference between two results): R = 10 C 10 Test report The test report shall include at least the followi
