43、ent, the terms and definitions in given in EN 12670:2001 and the following apply. 3.1 modular tile flat piece of natural stone square or rectangular in standard sizes, normally 610 mm obtained by cutting or splitting at a nominal thickness 12 mm 3.2 dimensions of modular tiles length l, width b and
44、thickness d are the dimensions of a modular tile. The dimensions are given in the stated sequence in millimetres (see Figure 1) Figure 1 Dimensions of a modular tile 4 Requirements 4.1 Requirements for geometric characteristics 4.1.1 General All measurements shall be carried out in accordance with E
45、N 13373 and all measured values of individual units shall fall within the required tolerances. 4.1.2 Requirements for dimensions, flatness and squareness The tolerances for sizes, flatness and squareness shall be as given in Table 1. Table 1 is not valid for modular tiles having natural cleft/riven
46、faces, for which tolerances on dimensions, flatness or squareness shall be declared by the manufacturer.

48、 dimensions; they are suitable to be fixed by thin mortar bed or adhesives 4.1.3 Requirements for surface finish 4.1.3.1 General Surface finishes shall extend uniformly to the edges of the modular tiles. The surface finishing of some types of stones may typically involve the use of patching, fillers
49、 or other similar products for natural holes, faults or cracks; this is to be considered as part of the normal processing. In such cases the type of treatment as well as the type and nature of additional materials shall be declared. 4.1.3.2 Requirements for surfaces after surface finishing Surfaces shall be worked to achieve the specified finish and shall have a regular appearance as a result of the finishing process (e.g. making reference to samples, see 4.2.3).
