23、 4 Test methods 4.1 Principle Pre-treatment impact puncturing is carried out at room temperature, where a conical weight is allowed to fall freely on to the waterproofing sheet. The degree of penetration is then assessed with the aid of dynamic water pressure testing. 4.2 Apparatus and materials Equ

24、ipment for impact puncturing, with a puncturing tool consisting of (1,0 0,01) kg of steel with a 90 conical point (see Figures 2 and 3). Concrete slab, according to EN 13375 for supporting the test specimen during impact puncturing. Suitable frame, for holding the test specimen firmly to the concret

25、e slab. Equipment for the water pressure test, with a dynamic water pressure applied (see Figures 4 and 5). 4.3 Preparation of test specimens Take test samples and test pieces in accordance with EN 13416. Select one test specimen of 400 mm 200 mm for testing. EN 14694:2005 (E) 6 In the case of a dou

26、ble sheet system, weld or glue the two sheets together according to manufacturer instructions. Ensure that the sheet or sheet system thickness is within the limits of the equipment used. Condition the test specimen for at least 24 h at a temperature of (23 2) C. 4.4 Procedure 4.4.1 Carry out the tes

27、ting at a temperature of (23 2) C. 4.4.2 Select on the test specimen of 400 mm 200 mm two circular sections of diameter 135 mm approximately. 4.4.3 Lay the test specimen on the horizontal concrete slab, with the upper side of the sheet facing upwards. Hold the test specimen down and in place with a

28、suitable frame. The sheet shall not be bonded to the concrete. 4.4.4 Impact the test specimen at 4 points in each circular section, ensuring that the 4 points are diametrically positioned within each circular section so that each point will fit into a disc slot according to Figure 5. Allow the punct

29、uring tool to fall freely and vertically from a specified height of (200 2) mm onto the surface of the test specimen. 4.4.5 Cut the two circular test specimens (diameter 135 mm approximately) from the pre-treated test specimen for water pressure testing. 4.4.6 Fill the apparatus for the water pressu

30、re test with water till overflowing. In testing, mount the circular test specimen firmly with the upper side of the sheet facing upwards in the equipment (see Figure 4). Place the slotted disc (see Figure 5), on top of the test specimen so that a punctured point appears in the middle of each slot, w

31、ith one of the slots being parallel to the longitudinal direction of the sheet. Progressively tighten until the test specimen is firmly in place, and dry where necessary with a cloth or with compressed air. 4.4.7 Under the influence of a specified dynamic water pressure, examine the circular test sp

32、ecimen to determine whether it remains impervious for a specified number of pulses. The dynamic pressure is defined in Figure 1. The water pressure is increased from 0 kPa to (500 5) kPa within 0,5 s, kept at that pressure for 2,5 s, decreased again within 0,5 s to 0 kPa and kept there for another 2

33、,5 s. The total time of a pulse is 5 s to 6 s. Perform 1 000 pulses of the dynamic water pressure test on both circular test specimens. If a visual inspection identifies a leakage in the test specimen, terminate the test and record the number of pulses. 0 0,5 p/Nmm 2 t s 2,5 0,5 2,5 0,5 Figure 1 Dyn

Repeat the test once if one of the two circular test specimens has leaked, and report the test results. If both circular test specimens of this repeated tes
