33、 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 materials4.2.1 Mastic asphalt, in accordance with EN 13375, with a substitution
34、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.9BS EN 14693:2017EN 14693:2017 (E)4.2.3 Stereo optical measuring instrument, with tenfold magnification and a reading accuracy of 0,1 mm.4.2.4 UV lighting

Ensur
37、e 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 Procedure4.4.1 Condition the sand layer, the concrete slab and the test specimen for at least 24 h
38、 at (23 2) C.10 BS EN 14693:2017EN 14693:2017 (E)4.4.2 Place the test specimen onto the concrete slab.

39、1 Illustration of pouring4.4.3 Lay the concrete slab with test specimen on the sand layer, and level it by means of the spirit level.4.4.4 Pour the mastic asphalt and distribute it softly using the float to fill the frame.4.4.5 Ensure that the temperature of the mastic asphalt on leaving the boiler
40、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 eight hours after pouring. After cooling, remove

42、urface 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.11BS EN 14693:2017EN 14693:2017 (E)4.5.1.3 Mark the sheet compound specks of this partial su

44、 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 the mastic asphalt. Apply the marks vertically to the upper con
45、crete 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 sheet, the mastic asphalt and the concrete slab respectively with a p
46、ointed 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 the reference thickness.4.5.2.5 Calculate the arithmetic mean of
47、the thickness of each test specimen to an accuracy of 0,1 mm.4.5.3 Determination of sheet compound inclusions in the mastic asphalt4.5.3.1 After a waiting period of at least 48 h, visually determine at both cutting edges of the test specimen any inclusions of sheet compounds, either bonded or not bo
48、nded 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 maximum height 12 mm from the underside of the sheet that are bonded to the
49、 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.12 BS EN 14693:2017EN 14693:2017 (E)Key1 with sheet non bonded inclusions2 with sheet bonded inclusions3 mastic asphalt4 sheet5 concrete slaba size of non bonded inclusionsb height of bonded inclusionsFigure 2 Illustration of inclusions4.6 Evaluation and expression of results4.6.1 Sheet compound specks on the surface of the mastic asphaltCalculate for ea
