21、eNo reproduction or networking permitted without license from IHS-,-,-EN 14691:2005 (E) 4 Introduction The purpose of the test is to determine the compatibility of the waterproofing system in the installed condition by determination of the shear strength properties before and after accelerated heat
22、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 concrete bridge decks are based on materials that are subject to oxidation, migration, diffusion, and absor
23、ption 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 effects. The use of an accelerated heat-conditioning test will allow the evaluation of the change in a specifi
24、c 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 will allow the determination of any change in properties together with an indication of any migrational
25、or interfacial long term incompatibility between the adherents.

31、erature 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 properties 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 con
32、ditioned and comparing the results with a reference set of test specimens that have not been heat conditioned. 4.2 Apparatus a) Oven, with circulating 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.
33、Copyright European Committee for Standardization Provided by IHS under license with CENNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-EN 14691:2005 (E) 6 4.3 Preparation of the test specimen Prepare the test specimens (Type 3) in accordance with EN 13375 for the t
34、est 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 tested
35、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 on top
36、 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 evide
37、nce 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 expre

40、e 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.
