EN 12057:2015 (E) 6 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 12670:2001 and the following apply. 3.1 modular tile flat piece of natural stone square or rectangular shapes, obtained by cutting or splitting at a nominal thickness ≤ 12 mm 3.2 dimensions of modular tiles length l, width b and thickness d, given in the stated sequence in millimetres (see Figure 1)

Figure 1 — Dimensions of a modular tile 3.3 calibrated tile tile which fulfil stricter tolerances for thickness, flatness and squareness 3.4 lower expected value lower expected value (EL) corresponds to the 5 %-quantile of a logarithmic normal distribution for a confidence level of 75 % 3.5 higher expected value higher expected value (EH) corresponds to the 95 %-quantile of a logarithmic normal distribution for a confidence level of 75 % 4 Characteristics of natural stone modular tiles 4.1 Geometrical characteristics 4.1.1 General All measurements shall be carried out in accordance with EN 13373 and all measured values of individual units shall fall within the required tolerances. SIST EN 12057:2015

EN 12057:2015 (E) 7 4.1.2 Dimensions The deviations for dimensions, flatness and squareness shall be as given in Table 1. Table 1 is not valid for modular tiles having natural cleft/riven faces, for which deviations on dimensions, flatness or squareness shall be set out by the manufacturer. Table 1 — Tolerances on dimensions and shape Property Tolerances on dimensions and shape Not calibrated tiles Calibrated tilesa Dimensions l, b ±1 mm ±1 mm d ±1,5 mm ±0,5 mm Flatness (for honed and polished surface only)b 0,15 % 0,10 % Squarenessb 0,15 % 0,10 % a Calibrated tiles indicate a product submitted to specific mechanical finishing in order to obtain more precise dimensions; they might be suitable to be fixed by thin mortar bed or adhesives b in accordance with EN 13373 4.1.3 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 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). For definitions of surface finishes, see EN 12670. 4.2 Physical and mechanical characteristics 4.2.1 General Whenever stone processing is likely to change the characteristics of the raw material (e.g. as a consequence of the type of processing or because the use of patching, fillers or other similar products for natural holes, faults, cracks and similar), then this has to be considered when determining the characteristics requested by this document. The following characteristics shall be declared where requested by this document or with reference to the use conditions. SIST EN 12057:2015

EN 12057:2015 (E) 8 4.2.2 Denomination The denomination shall always be declared in accordance with EN 12440 (it means traditional name, petrological family, typical colour and place of origin). NOTE The place of origin can be given by GPS coordinates. The petrographic definition shall be determined in accordance with EN 12407. 4.2.3 Visual appearance 4.2.3.1 General The colour, veining, texture, etc. of the stone shall be identified visually, typically by a reference sample of the same stone suitable for providing a general description of visual appearance. The reference sample shall be provided by the supplier. 4.2.3.2 Reference sample, visual inspection and acceptance criteria A reference sample shall be an adequate number of pieces of natural stone of sufficient size to indicate the general appearance of the finished work. The dimensions of individual pieces shall be at least 0,01 m2 (typical values are between 0,01 m2 and 0,25 m2 in face area but may be more), and shall indicate the range of appearance regarding the colouring, the vein pattern, the physical structure and the surface finish. In particular the reference sample shall show specific characteristics of the stone, such as typical holes, glass seams, spots and crystalline veins. The reference sample does not imply strict uniformity between the sample itself and the actual supply; natural variations may always occur. If the processing of the stone involves the use of patching, fillers or other similar products for natural holes, faults or cracks, then the reference sample shall similarly display the impact of the same on the finished surface. All the characteristics as shown by the reference sample shall be considered typical of the stone and not as flaws, therefore they shall not become a reason for rejection, unless their concentration becomes excessive and the typical character of the stone is lost. The name and address of the producer or the supplier, as well as the denomination of the stone in accordance with 4.2.2 above, shall be indicated on the reference sample. Any comparison between production sample and reference sample shall be carried out by placing the reference sample against the production samples and viewing them at a distance of about two metres under normal daylight conditions and recording any visible differences in the characteristics of the stones (see Figure 2).

Where the surface finish of the delivered product has an influence on the characteristic, the test shall be carried out with this finish, in accordance with the technological tests defined in EN 12372. 4.2.5 Bond strength/adhesion This standard does not consider fixing by means of mortar and adhesives. NOTE The value of the bond strength adhesion and the durability depend on several influences, e.g. the type of adhesive/mortar, the surfaces being bonded and the climatic conditions. SIST EN 12057:2015

EN 12057:2015 (E) 10 4.2.6 Water absorption at atmospheric pressure When required this characteristic shall be determined using the test method in EN 13755 and the higher expected value (EH) shall be declared. 4.2.7 Reaction to fire When required this characteristic shall be declared. Natural stone tiles may be considered reaction to fire Class A11) with the following exceptions. — Natural stones containing asphalt at greater than 1 % by mass or volume, whichever is the more onerous, and having a final use subject to fire regulations, shall be tested for reaction to fire and classified in accordance with EN 13501-1. — Whenever processing of natural stones involves the use of organic patching, fillers or other similar products for natural holes, faults, cracks or similar, at greater than 1 % by mass or volume, whichever is the more onerous and the same stones have a final use subject to fire regulations, then they shall be tested for reaction to fire and classified in accordance with EN 13501-1. 4.2.8 Water absorption by capillarity When required (e.g. when the modular tile is to be used for elements in contact with a horizontal surface where water may be present) this characteristic shall be determined using the test method in EN 1925 and the higher expected value (EH) shall be declared. For stone having an open porosity less than 1,0 % this test shall not be performed. 4.2.9 Apparent density and open porosity When required the apparent density and open porosity shall be determined using the test method in EN 1936 and the mean values of the results declared. 4.2.10 Durability 4.2.10.1 Durability of flexural strength against freeze thaw When required the frost resistance shall be determined using the test method in EN 12371 and the results declared: — as the value of the flexural strength without frost and after 56 cycles of freeze/thaw for flooring and after 14 freeze/thaw cycles for wall finishes by giving the mean value; — or in case the stone failed before 56 cycles or 14 cycles, respectively, as the number of cycles necessary to initiate cracks, rupture, etc. For some specific uses it may be appropriate to use different test cycles, for example freezing in water, freezing to a lower temperature, or testing specimens embedded in non-porous siliceous granules or a different number of cycles. In these cases national specification standards may be followed but these variations shall be clearly stated in the test report and in the product marking. NOTE The selection of the stone is subjected to climatic zone and/or to codes of practice.

EN 12057:2015 (E) 11 When the mean value of flexural strength decreases by less than 20 %, this should not be considered as significant because of the variability of natural stone. 4.2.10.2 Abrasion resistance When required, this characteristic shall be declared, for tiles for flooring and stairs only, and shall be determined using the test method in EN 14157 and the higher expected value (EH) shall be declared and expressed in millimetres when under method A or in cm3/50 cm2 under method B. 4.2.10.3 Resistance to thermal and moisture cycling The resistance of marble to thermal and moisture cycling shall be declared upon request only for marble intended for cladding of building facades and determined according to EN 16306. For scientific definition of marble, see EN 12670:2001, 2.1.243 a. 4.2.11 Thermal shock resistance When required this characteristic shall be declared and determined using the test method in EN 14066 and the changes both in mass and in flexural strength expressed accordingly. 4.2.12 Water vapour permeability This characteristic shall be declared when the tile is to be used in a location subject to vapour control requirements. The permeability coefficient shall be tested or given as tabulated values in accordance with EN ISO 12572 and/or EN ISO 10456. 4.2.13 Slip resistance This characteristic shall be declared, for tiles for flooring and stairs only, where subject to regulatory requirements or upon request and when the roughness of the surface is less than 1 mm measured following EN 13373. The slip resistance shall be determined using test methods in CEN/TS 16165:2012, Annex C and the results expressed accordingly. Whenever results indicate an insufficient slip resistance of tiles for stairs, then adequate provisions shall be adopted in order to improve this parameter. This may be achieved by mechanical reworking of the surface, or by inserting anti-slip products e.g. rubber profiles, carborundum strips, metal bars or similar. 4.2.14 Skid resistance This characteristic shall be declared only, where subject to regulatory requirements or upon request and when the roughness of the surface is less than 1 mm measured following EN 13373. The skid resistance shall be determined as slip resistance (see 4.2.13). 4.2.15 Tactility This characteristic shall be declared, for tiles for flooring and stairs only, where subject to regulatory requirements or upon request.
