EN 197-1, Cemenf - Par 1: Composifion, specificafions and conformify criferia for common cemenfs. 3 Principle This test consists of applying a force in
27、 a direction perpendicular to the face of a specimen through a dowel previously placed in an hole drilled in one of its sides and measuring the breaking load of the specimen. Symbols is the thickness of the test specimen, in millimetres is the distance from the hole wall to the face where fracture o
28、ccurs, in millimetres is the maximum distance of the centre of the hole to the fracture edge on the face, in millimetres is the individual breaking load, in newtons is the mean value of d, in millimetres is the mean value of F, in newtons is the mean value of b, , in millimetres 4 EN 13364:2001 (E)
29、5 Apparatus 5.1 A balance capable of weighing the specimens with an accuracy of 0,Ol % of their mass. 5.2 A ventilated oven capable of maintaining a temperature of (70 f 5) OC. 5.3 A linear measuring device with an accuracy of 0,05 mm. 5.4 A rotary drilling machine equipped with a diamond or tungste
30、n carbide tipped bit. 5.5 A testing machine of appropriate force in accordance with EN 12390-4 and calibrated according to this standard. 5.6 A clamping device consisting of two metal plates having the shape and sizes shown in Figure 1. 5.7 A device for applying loads perpendicular to the axis of th
31、e dowel (see Figure 2). 5.8 A room or chamber in which the temperature of the air can be maintained at (20 f 5) OC. 6 Preparation of the specimens 6.1 Sampling and position of bedding The sampling is not the responsibility of the test laboratory except where specially requested. The position of any
32、bedding or anisotropy shall be indicated on each specimen by means of at least two parallel lines. 6.2 Test specimens 6.2.1 General The test can be carried out as an identification test or as a technological test. Identification tests are tests carried out when the use of the stone with respect to t
33、he position of the planes of anisotropy and the thickness and surface finish of the elements in the cladding are not known. Technological tests are those carried out when the use of the stone with respect to the position of the planes of anisotropy and the thickness and surface finish of the element
34、s in the cladding are known. In this case the major faces of the specimens shall have the same orientation of the face that will be loaded during use. 6.2.2 Number of specimens The minimum number of test specimens depends on the presence of planes of anisotropy. If the stone does not show planes of
35、anisotropy 10 tests of Type O (see Figure 3) shall be made on three specimens. If the stone shows planes of anisotropy: 10 tests of Type I (see Figure4) shall be made on three specimens cut parallel to the planes of anisotropy; 10 tests of Type Ila (see Figure 5) and 10 tests of Type Ilb (see Figure
36、 6) shall be made on five specimens cut perpendicular to the planes of anisotropy. 5 EN 13364:2001 (E) Dimensions in millimetres a) General view b) Detail of a plate suitable for tests on specimens having dimensions of 200 mm x 200 mm Key 1 Specimen 2 Dowel 3 Metal plate F L Length of the specimen d

40、shall be sawn, honed or polished. b) Technological test The surface finish on the faces and sides of the specimens shall be carried out according to the application (for example sawn, honed, polished, sanded, rubbed, flamed, bush-hammered, riven). 8 EN 13364:2001 (E) Thickness 6.2.4 Dimensions of th
41、e specimens a) Identification test The specimens are square slabs with faces (200 f 1) mm and a thickness of (30 f 3) mm. The permissible deviation on the squareness is a maximum of 2 mm. b) Technological test Di mens i o ns The specimens are square slabs with the following dimensions: I20 mm to 65
42、mm 1200 mm x 200 mm I I 65 mm to 80 mm 1300 mm x 300 mm I 6.2.5 Location of the holes a) Identification test The centre of the hole shall be situated between 98 mm and 102 mm from the other sides, measured to the nearest 0,5 mm. The thickness of stone between the edge of the hole and the two faces s
43、hall be (IO f 2,O) mm, measured to the nearest 0.5 mm. b) Technological test The centre of the hole shall be situated in the middle of the specimens length. The thickness of stone between the edge of the hole and the face to be tested shall be according to the application, measured to the nearest 0,
44、5 mm. 6.2.6 Dimensions and tolerances of the holes a) Identification test The diameter of the holes shall be (IO f 0,5) mm. The depth of the holes shall be (30 f 2) mm. b) Technological test The diameter of the holes shall be in accordance with the requirement of the application. The depth of the ho
45、le shall be (30 f 2) mm. 6.2.7 Drilling the holes The holes shall be wet drilled with a diamond or tungsten carbide tipped drill bit without hammering. 9 EN 13364:2001 (E) 6.2.8 Planes of anisotropy If the stone shows planes of anisotropy, the specimens are to be prepared in accordance with one of t
46、he arrangements shown in Figures 4, 5 and 6 and the position of the bedding or anisotropy is to be marked on the specimen by at least two parallel lines. If the use of the stone with respect to the position of the planes of anisotropy is known, the test shall be carried out with the force applied on
47、 dowel placed in the hole in the side corresponding to the face that will be loaded during use. If the use of the stone with respect to the position of the planes of anisotropy is not known or if more than one anisotropy is likely to be present, then the test shall be carried out in three perpendicu
48、lar orientations and the total number of tests will be 30. 6.2.9 Conditioning The specimens shall be dried to constant mass at (70 f 5) “C in a ventilated oven after the drilling of the holes but before the dowels are fixed in place. Constant mass is reached when the difference between two weighings
49、 carried out (24 f 2) h apart is less than 0,l % of the first of the two masses. After drying and prior to placing the dowels the specimens shall be stored at (20 f 5) “C until the thermal equilibrium is reached. 6.2.10 Measuring d and d, After conditioning the thickness (d) and the distance from the edge of each hole to the lower face of the specimen in the direction of the force (d,) shall be measured to the nearest 0,5 mm. 7 Dowels 7.1 Dimensions and tolerances a) Identification test The diameter of the dowels shall be (6,O f 0,l) mm.
