The tensile force shall be applied
23、 perpendicular to the test specimen, and the force required at failure shall be registered. 4.2 Apparatus and materials a) Tensile test machine, with force increasing rate control and automatic load recording, fitted with suitable clamps and base to ensure that the tensile force can be applied witho
24、ut momentum perpendicular to the test specimen. b) Circular steel plates, with a diameter of 50 mm, or square steel plates with test area (50 50) mm, and a tolerance of 0,5 mm. The steel plate shall be attached by suitable means (e.g. screwed) to the tensile test machine. Minimum thickness of steel
25、plate shall be 10 mm from bottom of steel plate to bottom of screw hole. c) Suitable adhesive (e.g. two part epoxy resin), for bonding the steel plates to the waterproofing sheet or the asphalt layer of the test specimen. d) Oven, capable of maintaining a temperature of (23 2) C. e) Device for measu
26、ring surface temperature, with an accuracy of at least 0,5 C. EN 13596:2004 (E) 6 4.3 Preparation of test specimens Samples and test pieces shall be taken in accordance with EN 13416. Compound specimen and test specimen preparations are described and specifications for base specimens and asphalt lay
27、er mixes are given in EN 13375. Type 1 (waterproofing sheet and concrete): Base specimen with the applied flexible sheet waterproofing shall be used if bond strength between waterproofing sheet and concrete substrate is to be measured. If the flexible sheet system consists of more than one sheet lay
28、er, only the bottom sheet layer shall be applied and tested. (Illustrated in Figure 1.) Type 2 (waterproofing sheet and asphalt layer): Flexible sheet sample applied with an asphalt layer shall be used if bond strength between waterproofing sheet and asphalt layer is to be measured. If the flexible
29、sheet system consists of more than one sheet layer, only the top sheet layer shall be applied with an asphalt layer and tested. After preparation the compound specimen shall be turned up side down (with the waterproofing facing upwards). Type 3 (concrete, waterproofing system and asphalt layer): Bas
30、e specimen with the applied flexible sheet waterproofing system and asphalt layer shall be used if bond strength of the complete waterproofing system and including the asphalt layer (the weakest link of the system) is to be measured. For type 3 only sawn test specimens 50 mm 50 mm shall be used. Aft
31、er preparation of test specimen(s) according to EN 13375 and cooling to room temperature, steel plates (4.2 b) shall be bonded to the upper surface of the test specimen (waterproofing sheet for type 1 and 2 or asphalt layer for type 3) with a suitable adhesive (4.2 c). For type 1 and 2 the test area
32、s shall then be isolated by cutting the sheet along the sides of the steel plate down to the concrete (type 1) or to the asphalt layer (type 2). Test specimen areas may be cut before bonding the steel plates. At least three test areas shall be prepared and any preparation shall not affect the struct
33、ure of the material. NOTE Enough test specimens should be prepared to ensure a minimum acceptable number of tests with an acceptable type of failure. If necessary the test area surface is prepared, before bonding the steel plates to the surface, by for instance using a metal brush. EN 13596:2004 (E)
34、 7 Key 1 Steel plate 2 Waterproofing sheet 3 Concrete Figure 1 Example of equipment and specimen for determining bond strength (between waterproofing sheet and concrete substrate) 4.4 Procedure Prior to testing the test specimen shall be conditioned at test temperature for at least 24 hours. The tes
35、t specimen is placed in the tensile test machine and the steel plate attached to the machine. During testing the steel plate is pulled with an increasing stress rate to assure an increase in tensile force of (0,15 0,01) N/s mm 2applied perpendicular to the test specimen. The tensile bond failure loa
36、d shall be recorded together with the mode of failure. The following general modes of failure may occur for a system of flexible bitumen sheet and primer: in the concrete; between concrete and primer; in the primer layer; between primer and weldable or pour-and roll bitumen; in the weldable or pour-
37、and roll bitumen; against or within the reinforcement; between sheet and granules; adhesive failure. With an applied flexible sheet waterproofing system and asphalt layer failure may occur also: between asphalt layer and sheet; EN 13596:2004 (E) 8 in the asphalt layer. The test is carried out at (23
38、 2) C. NOTE 1 Additionally other temperatures can be used if required. Three valid tests shall be carried out for each test temperature. The mean bond strength shall be calculated from a minimum of three accepted test results. The surface temperature shall be measured for each test area immediately
39、after finishing the test. NOTE 2 The result of the test depends significantly on the test temperature. 4.5 Expression of results 4.5.1 Method of calculation Bond strength shall be calculated, to the nearest 0,1 N/mm 2 , as the stress at maximum force by the following equation: max= F max/ A where ma
40、xis the bond strength at failure, in N/mm ; F maxis the maximum force, in N; A is the test area, in mm . The arithmetical mean value of the three test results shall be calculated. 4.5.2 Precision of the test method The precision of the test method is not specified. 5 Test report The test report shal
41、l include at least the following information: a) all details necessary to identify the product tested and identification of the whole waterproofing system including asphalt layer and application temperature, type and quantity of the primer; b) a reference to this document (EN 13596) and any deviatio
42、n from it; c) information on preparation of test specimens in accordance with 4.3 and EN 13375, specimens prepared by and witnessed by which organisation; d) information about the procedure in accordance with Clause 4.4, test temperature, surface temperature and test area; e) the test results and fa
43、ilure mode according to Clause 4.5 for each individual test, mean value if relevant; f) the dates of delivery and preparation of specimens; g) the date of tests. blankBS EN 13596:2004 BSI 389 Chiswick High Road London W4 4AL BSI British Standards Institution BSI is the independent national body resp
