BS EN 1469:2015EN 1469:2015 (E) 5 1 Scope This European Standard specifies requirements for slabs of natural stone th
27、at are made for use as cladding for internal and external wall and ceiling finishes. This European Standard does not cover aggregates and artificially agglomerated stone material and does not cover installation. Furthermore, this European Standard does not cover roofing slates used as external cladd
28、ing and slates and stone products for discontinuous roofing. This European Standard does not consider fixing by means of mortar and adhesives. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

35、 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 sla
36、b 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
37、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 shal
38、l 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 T
39、able 1. BS EN 1469:2015EN 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 im
40、portant 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 techni
41、cal 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
42、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 t
43、han 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 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
44、 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). BS EN 1469:2015EN 1469:2015 (E) 8 Each slab angle shall be in accordance with the agreed
45、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
46、 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,
47、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 manufact
48、urer. 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.
49、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. BS EN 1469:2015EN 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
