Mortar as defined in EN 998-1. Adhesives as defined in EN 12004. 3.1.1 skirting flat piece of natural stone obtained by cutting or splitting at a nominal thickness > 12 mm. It is laid on each wall surrounding a flooring and in contact with it 3.2 slab for stairs flat piece of natural stone obtained by cutting or splitting at a nominal thickness >12 mm (except risers) to form the horizontal part of a stair step (tread) or the vertical part of a stair step (riser)

3.3.1 length l, width b and thickness d are the dimensions of a slab for floors. The dimensions are given in the stated sequence in millimetres (see Figure 1) 3.3.2 length l, width b and thickness d are the dimensions of a slab for stairs, separated for treads and risers. The dimensions are given in the stated sequence in millimetres (see Figure 2)

Table 1 – Tolerances on the nominal thickness Nominal thickness
in mm Tolerance More than 12 Up to and including 15 ± 1,5 mm More than 15 Up to and including 30 ± 10 % More than 30 Up to and including 80 ± 3 mm More than 80 ± 5 mm
Stricter tolerances may be declared by the manufacturer.

Stricter tolerances may be declared by the manufacturer. 4.1.5 Requirements for angles and special shapes The permissible tolerance at any point shall be as stated in Table 2 (see Figure 3). 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 tolerance at any point shall be as stated in Table 2 (see Figure 3). Stricter tolerances may be declared by the manufacturer.

The slab sides shall fall within the two dotted lines indicating the tolerances of length and width according to
Table 2 Figure 3 – Example of tolerances on angles 4.1.6 Commercial sizes of slabs for floors and stairs Commercial sizes shall be based on the area of the smallest possible circumscribed rectangle measured in square metres accurate to two decimal places. 4.1.7 Requirements for surface finish 4.1.7.1 General Surface finishes shall be carried out uniformly to the edges of the slabs for floors and stairs. The surface finishing of some types of stones may typically involve the use of patching, fillers or adhesives 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. 4.1.7.2 Requirements for 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 on all exposed surfaces (e.g. making reference to samples, see 4.2.3), agreed in accordance with samples submitted and agreed beforehand between the purchaser and supplier. NOTE 1 Surfaces obtained by grinding are, for example: – rough ground surfaces obtained, e.g. by means of a grinding disk of grain size F 60; – medium ground surfaces obtained, e.g. by means of a grinding disk of grain size F 120; – fine ground surfaces obtained, e.g. by means of a grinding disk of grain size F 220; – matt finished surfaces obtained, e.g. by means of a
grinding disk with grain size F 400; – highly polished surfaces obtained, e.g. by means of a polishing disk or felt. NOTE 2 Surfaces obtained by means of percussion tools are, for example: – bush hammered surfaces (see EN 12670:2001, 2.3.8)*;

The flexural strength shall be determined using the test method in EN 12372 or EN 13161 and the mean value, lower expected value and document deviation shall be declared. NOTE An identification test as defined in EN 12372 or EN 13161 is normally carried out for the purpose of CE marking. However, where the surface finish of the delivered product is known, the test may be carried out with this finish, in accordance with the technological tests defined in EN 12372 or EN 13161. 4.2.5 Bond strength adhesion This characteristic is within the responsibility of the person in charge of the execution of the tiling. The value of the bond strength adhesion depends on the condition of the layer, the type of adhesive/mortar and the surface finish of the back face. The person responsible shall refer to existing national codes of practice.
