EN 1469:2015 (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 slab for cladding slab cut to size to be used as cladding for internal and external walls and may be fixed or suspended at any angle 3.2 dimensions of slabs for cladding length l, width b and thickness d are the dimensions of a slab for cladding for external and internal use Note 1 to entry: Dimensions are given in the stated sequence in millimetres (see Figure 1).

Figure 1 — Dimensions of a slab for cladding 3.3 lower expected value lower expected value (EL) corresponds to the 5 %-quantile of a logarithmic normal distribution for a confidence level of 75 % 3.4 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 for cladding 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. 4.1.2 Thickness The thickness shall be measured in accordance with EN 13373 and the measured values shall not deviate from the nominal thickness by more than given in Table 1. SIST EN 1469:2015

EN 1469:2015 (E) 7 Table 1 — Tolerances on the nominal thickness Nominal thickness Tolerance in mm More than 12

Up to and including 30 ±10 % More than 30

Up to and including 80 ±3 mm More than 80 ±5 mm Stricter deviations may be declared by the manufacturer. This is particularly important when the edges of the slabs will be visible after installation. NOTE If the slab is to be fixed by adhesive or a thin mortar bed, stricter tolerances may be needed. The required thickness of slabs shall result from a structural analysis or similar procedure that takes into account the technical and physical properties of the stone and the intended application. For natural cleft/riven faces, Table 1 does not apply and the deviations on thickness shall be set out by the manufacturer. 4.1.3 Flatness The deviation from flatness of the surface (except for natural cleft faces) when measured in accordance with EN 13373 shall not exceed 0,2 % of the slab length, and shall not exceed 3 mm. For natural cleft faces, the tolerance on flatness shall be declared by manufacturer. 4.1.4 Length, width and squareness The length, width or squareness shall not deviate from the nominal size by more than the tolerances given in Table 2. Measurements shall be made according to EN 13373. Table 2 — Tolerances on length, width and squareness Nominal length or width in mm < 600 ≥ 600 Sawn edges thickness ≤ 50 mm ±1 mm ±1,5 mm Sawn edges thickness > 50 mm ±2 mm ±3 mm Squareness ±1 mm ±2 mm Stricter deviations may be declared by the manufacturer. For natural cleft/riven edges, Table 2 does not apply and the tolerances on length, width and squareness shall be set out by the manufacturer. 4.1.5 Special shapes The permissible deviation at any point shall be as stated in Table 2 (see Figure 2). SIST EN 1469:2015

EN 1469:2015 (E) 8 Each slab angle shall be in accordance with the agreed geometry. Pieces of special or irregular shape shall be checked for compliance with the required shape by use of a suitable template, the permissible deviation at any point shall be as stated in Table 2. Stricter deviations may be declared by the manufacturer. This is particularly important when the edges of the slabs will be visible. Dimensions in millimetres

Key 1 nominal size 2 the slab sides shall fall within the two dotted lines indicating the tolerances of length and width according to Table 2 Figure 2 — Example of tolerances on angles 4.1.6 Location of dowel holes The specified location, depth and diameter (shape) of dowel holes shall be as follows: — Location measured along the length or width of the slab: ± 2 mm — Location measured along thickness: ± 1 mm (to be measured from the exposed face) — Depth: + 3 / - 1 mm — Diameter: + 1 / - 0,5 mm Stricter deviations may be declared by the manufacturer. For other fixing systems (e.g. slots), specific deviations shall be declared by the manufacturer. 4.1.7 Commercial sizes of slabs for cladding Commercial sizes shall be based on the area of the smallest possible circumscribed rectangle measured in square metres accurate to two decimal places. NOTE For small units it may be necessary to agree a minimum size, for example 0,25 m2. 4.1.8 Surface finish 4.1.8.1 General Surface finishes shall be carried out uniformly to the edges of the cladding slab. SIST EN 1469:2015

EN 1469:2015 (E) 9 The surface treatment 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. 4.1.8.2 Surfaces after surface finishing Surfaces shall have a regular appearance as a function of the finishing process and shall be worked to meet the specified finish (e.g. making reference to samples, see 4.2.3) on all exposed surfaces. For definitions of surface finishes see EN 12670. 4.2 Physical and mechanical characteristics 4.2.1 General When during production the products have been subjected to a treatment that alters the properties of the stone (e.g. chemical or physical treatment, patching or filling or other similar products for natural holes, faults or cracks) then the use of such treatment shall be stated and changes to the physical and chemical properties considered. In addition, specimens for testing shall be representative of the product and any process(es) that the stone is subjected to. The following characteristics shall be declared where requested by this standard or with reference to the intended use conditions. 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 When required this characteristic shall be declared. 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 manufacturer. 4.2.3.2 Reference sample, visual inspection and acceptance criteria A reference sample shall be an adequate number of specimens 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 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, crystalline veins and rusty spots. The reference sample does not imply strict uniformity between the sample itself and the actual supply; natural variations may always occur. SIST EN 1469:2015

EN 1469:2015 (E) 10 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 3).

Key 1 reference sample 2 production sample 3 daylight Figure 3 — Comparison between production sample and reference sample SIST EN 1469:2015

EN 1469:2015 (E) 11 All visible variations such as cracks, inclusions, cavities, stylolites and veins are permitted as far as they are typical for the stone and the performance of the stone is not adversely affected. 4.2.4 Flexural strength When required this characteristic shall be declared. The flexural strength shall be determined using the test method in EN 12372 and the mean value, lower expected value and standard deviation shall be declared. 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 Resistance to fixings The characteristic is carried out by determining the breaking load at a dowel hole. It shall be declared when the slabs are to be mechanically fixed using dowels on the edges. The breaking load at a dowel hole shall be determined using the test method in EN 13364 and the mean value, lower expected value and standard deviation shall be declared. 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 13364. If a different mechanical fixing is to be used the suitability of the stone is determined from a structural analysis taking into account the location and the technical properties of the material. Anchor holes shall not be drilled by percussion drilling machines. 4.2.6 Water absorption at atmospheric pressure When required this characteristic shall be declared. Where required the water absorption 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 stones are considered reaction to fire Class A1 following Commission Decision 96/603/EC, as amended, 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 this characteristic shall be declared (e.g. when the cladding slab is to be used for elements in contact with a horizontal surface where water may be present). SIST EN 1469:2015

EN 1469:2015 (E) 12 The water absorption by capillarity shall be determined using the test method in EN 1925 and expressed as higher expected value (EH). 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 this characteristic shall be declared. The apparent density and open porosity shall be determined using the test method in EN 1936 and the mean values of the results expressed accordingly. 4.2.10 Durability 4.2.10.1 Durability of flexural strength against freeze thaw When required this characteristic shall be declared. The frost resistance shall be determined using the test method in EN 12371 and the results expressed: — as the value of the flexural strength without frost and after 14 freeze/thaw cycles by giving the mean value; The physical properties of all stones vary within a normal range. Therefore, to evaluate the change in fl
