30、 the breaking load of the specimen. 4 Symbols d is the thickness of the test specimen, in millimetres d 1 is the distance from the hole wall to the face where fracture occurs, in millimetres b A is the maximum distance of the centre of the hole to the fracture edge on the face, in millimetres F is t

34、paration 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 bedding or anisotropy shall be indicated on each specimen by means of at least two parallel lines. 6.2 Test specimens 6.2

35、.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 the position of the planes of anisotropy and the thickness and surface finish of the elements in the cladding are not know

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 elements in the cladding are known. In this case the major faces of the specimens shall have the same orientation of the face th

37、at 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 anisotropy 10 tests of Type 0 (see Figure 3) shall be made on three specimens. If the stone shows planes of anisotropy: 1

38、0 tests of Type I (see Figure 4) shall be made on three specimens cut parallel to the planes of anisotropy; 10 tests of Type IIa (see Figure 5) and 10 tests of Type IIb (see Figure 6) shall be made on five specimens cut perpendicular to the planes of anisotropy.EN 13364:2001 (E) 6 Dimensions in mill

If the use of th

49、e stone with respect to the position of the planes of anisotropy is known, the test shall be carried out with the force applied on 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 perpendicular orientations and the total number
