DIN EN 14693:2017-07 EN 14693:2017 (E) 4 Introduction The purpose of the test is to determine the behaviour of the waterproofing sheet which is in contact with the mastic asphalt during application. DIN EN 14693:2017-07 EN 14693:2017 (E) 5 1 Scope This European Standard is

24、applicable to waterproofing sheets intended for use with a layer of mastic asphalt. This European Standard specifies a test method for the evaluation of the resistance of waterproofing sheets to the rising of the sheet at the application of mastic asphalt in a non-floating manner. NOTE This European

25、 Standard can also be used for waterproofing sheets intended for use with other asphalt types as a protection layer. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

30、oints are determined: quantity of sheet-compound specks on the surface of the mastic asphalt; quantity of sheet-compound inclusions within the mastic asphalt; changes in thickness of the waterproofing sheet. 4.2 Apparatus and materials 4.2.1 Mastic asphalt, in accordance with EN 13375, with a substi

31、tution of 4 % to 5 % by mass of filler by iron oxide powder (Fe2O3). 4.2.2 Mastic asphalt boiler, with motor-driven stirring device and indirect heating.

33、and, with a depth of 80 mm to 100 mm natural sand. 4.2.9 Spirit level. 4.2.10 Saw. 4.2.11 Float for mastic asphalt. 4.2.12 Screw clamps. 4.2.13 Transparent foil. 4.3 Preparation of test specimens Take samples and test specimens in accordance with EN 13416, the dimensions of the test specimens are (4

34、00 10) mm (400 10) mm. Ensure that the test specimens are without any mechanical damage. The thickness of the sheet, determined in accordance with EN 1849-1, shall be known (reference thickness). Two concrete slabs are required. 4.4 Procedure 4.4.1 Condition the sand layer, the concrete slab and the

35、 test specimen for at least 24 h at (23 2) C. 4.4.2 Place the test specimen onto the concrete slab. Position the frame on top of the test specimen and concrete slab, and fix it with screw clamps.

37、ture of the mastic asphalt on leaving the boiler is (220 3) C before pouring, and also that the pouring height of the mastic asphalt from the upper surface of the test specimen is between 100 mm and 150 mm. Complete the pouring of the mastic asphalt within two minutes, and leave to cool for at least

38、 eight hours after pouring. After cooling, remove the frame. 4.5 Measurements 4.5.1 Determination of surface proportion of any sheet compound specks on the surface of the mastic asphalt 4.5.1.1 Determine the mass of the square partial surface of the transparent foil with an area of (50 1) mm (50 1)

39、mm, m1. 4.5.1.2 Visually determine a square partial surface of (50 1) mm (50 1) mm of the mastic asphalt surface, on which the total area taken up by the sheet compound specks holds the biggest share. In case of doubt, the use of UV illumination is recommended. 4.5.1.3 Mark the sheet compound specks

40、 of this partial surface on transparent foil and cut out the specks. DIN EN 14693:2017-07 EN 14693:2017 (E) 8 4.5.1.4 Determine the mass of the cut-out segments of the foil, m2. 4.5.2 Determination of the thickness of the sheet after pouring the mastic asphalt 4.5.2.1 Saw the test specimen (made up

41、of the concrete slab, sheet and mastic asphalt) parallel to the lateral face into three equal parts. Use the middle part as a test specimen for further testing. 4.5.2.2 Make fine pencil marks at each 25 mm on both cut surfaces of the test specimen. The first mark shall be made 10 mm from the edge of

42、 the mastic asphalt. Apply the marks vertically to the upper concrete surface on both sides of the sheet. 4.5.2.3 Determine the thickness of the sheet at each pencil mark to an accuracy of 0,1 mm in the stereo optical measuring instrument. In cases of doubt, determine the borderline between the shee

43、t, the mastic asphalt and the concrete slab respectively with a pointed object. Any mineral particles distributed from the sheet surface protection shall be considered as part of the sheet. 4.5.2.4 Substitute any determined individual value that is bigger than the reference thickness of the sheet by

44、 the reference thickness. 4.5.2.5 Calculate the arithmetic mean of the thickness of each test specimen to an accuracy of 0,1 mm. 4.5.3 Determination of sheet compound inclusions in the mastic asphalt 4.5.3.1 After a waiting period of at least 48 h, visually determine at both cutting edges of the tes

45、t specimen any inclusions of sheet compounds, either bonded or not bonded to the sheet. 4.5.3.2 Such inclusions of a size 7 mm (distance between the extreme points of the inclusions) that are not bonded to the sheet shall be marked and counted accordingly. 4.5.3.3 Sheet compound inclusions of a maxi

46、mum height 12 mm from the underside of the sheet that are bonded to the sheet, shall be marked and counted accordingly. 4.5.3.4 The total number of both types of inclusions on each test specimen is calculated.
