DIN EN 14691:2017-07 EN 14691:2017 (E) 4 Introduction The purpose of the test is to determine the compatibility of the waterproofing system in the
21、 installed condition by determination of the shear strength properties before and after accelerated heat conditioning. Waterproofing systems are required to maintain performance over extended periods of time once installed on a concrete structure. Many flexible sheets used in the waterproofing of co
22、ncrete bridge decks are based on materials that are subject to oxidation, migration, diffusion, and absorption of components within the system itself and/or those to which the system is adhered. These physico-chemical effects occur over time, however increased temperature will accelerate these effec
23、ts. The use of an accelerated heat-conditioning test will allow the evaluation of the change in a specific mechanical property, shear strength, over a significantly shorter time period than allowing the waterproofing system to age under normal ambient conditions. The use of the shear resistance test
24、 will allow the determination of any change in properties together with an indication of any migrational or interfacial long-term incompatibility between the adherents. DIN EN 14691:2017-07 EN 14691:2017 (E) 5 1 Scope This European Standard specifies a test method for the evaluation of the compatibi
25、lity of the waterproofing system applied to a concrete surface and covered with an asphalt layer. The complete system is exposed to an accelerated heat conditioning followed by a determination of the shear strength properties before and after heat conditioning. 2 Normative references The following d

30、en in EN 13416, EN 13375, EN 14695, prEN 17048 and the following apply. 3.1 heat conditioning process whereby the test specimen is held at an elevated temperature for a specified period of time 4 Test methods 4.1 Principle To detect by a change of the shear resistance if any changes occur in propert
31、ies of test specimens when they are subjected to accelerated heat conditioning. This is achieved by testing a set of test specimens that have been heat conditioned and comparing the results with a reference set of test specimens that have not been heat conditioned. 4.2 Apparatus a) Oven, with circul
32、ating air (without fresh supply), capable of maintaining (50 2) C. b) Loading and support device, capable of meeting the requirements set out in EN 13653. DIN EN 14691:2017-07 EN 14691:2017 (E) 6 4.3 Preparation of the test specimen Prepare the test specimens (Type 3) in accordance with EN 13375 for
33、 the test method according to EN 13653, and cool to room temperature. Four test specimens are used for the heat conditioning, and four reference test specimens are used for comparison. 4.4 Procedure 4.4.1 Condition the four reference test specimens at (23 2) C for at least 24 h prior to them being t
34、ested in accordance with EN 13653. 4.4.2 Place the remaining four test specimens horizontally in an air-circulating oven in such a way as to allow free movement of air over and around the test specimen. Maintain the temperature in the oven at (50 2) C. Ensure that the test specimens are not stacked
35、on top of each other. 4.4.3 Remove the test specimens from the oven after a period of 91 days, and allow to condition at (23 2) C for 24 h prior to being tested for shear strength in accordance with EN 13653. 4.4.4 Before and after the test for shear strength, visually inspect the test specimens for
36、 evidence of migration and separation of component layers. NOTE Migration and separation can take the form of a build-up of a semi liquid layer at the interfaces of the waterproofing systems. 4.5 Expression of results The results shall be expressed in accordance with EN 13653. Compatibility C (%) is
37、 expressed by: 001 100max maxCmaxC=(1) where max 0is the mean value of shear strength of reference test specimens max Cis the mean value of shear strength of conditioned specimens NOTE There is no precision data currently available for this test method. 4.6 Test report The test report shall include
38、at least the following information: a) all details necessary to identify the product tested; b) reference to this European Standard and any deviation from it; c) information about preparation of test specimens in accordance with 4.3; d) information about the procedure in accordance with 4.4; e) test
39、 result with the force displacement plot and failure mode for each individual shear test according to 4.4 and compatibility in accordance with 4.5; f) visual inspection of the condition of the conditioned test specimen as compared with the control; g) dates of delivery and preparation of specimens; h) date of tests. a) DIN EN 14691:2017-07
