Figure 1 — Dimensions of a modular tile 4 Requirements 4.1 Requirements for geometric characteristics 4.1.1 General All measurements of geometrical characteristics of modular tiles as given in the following clauses shall be carried out in accordance with EN 14617-16. 4.1.2 Dimensions The dimensions of modular tiles shall always be declared (see 3.2). 4.1.3 Size and shape The tolerances for size and shape of modular tiles shall be as given in Table 1. Stricter tolerances than those given in Table 1 may be declared by the manufacturer. This is particularly important when tiles are to be fixed with adhesive.

± 0,5 mm Thickness ± 0,7 mm Straightness of sides ± 0,3 mm Rectangularity ± 0,9 mm Flatness: – centre curvature – edge curvature – warping ± 2 % referred to length
If the tile is required to be bevelled (when no other specification is made), the angle of the bevel shall be 45° and the width of the bevel shall be 1,0 mm with a tolerance of ± 0,7 mm. 4.1.4.2 Surfaces after finishing Surfaces of modular tiles shall have a regular appearance as a function of the finishing process and shall be worked to meet the finish declared (e.g. by submission of samples beforehand between the manufacturer and purchaser). Examples of the surface finishes are: a) surfaces with texture in relief obtained by copying the design of the mould (e.g. hand-splitted or artistic design); b) fine ground surfaces, obtained e.g. by means of a grinding disk of grain size F 220; c) matt finished surfaces, obtained e.g. by means of a polishing disk with grain size F 400; d) highly polished surfaces, obtained e.g. by means of a polishing disk or felt. 4.2 Requirements for flooring and stairs modular tiles made of agglomerated stones 4.2.1 General The values for the characteristics in 4.2.2 to 4.2.17 shall be declared for flooring and stairs modular tiles made of agglomerated stones when subject to regulatory requirements and may be declared otherwise with reference to the intended end use conditions. The classification of flooring and stairs tiles according to water absorption, flexural strength, abrasion resistance and chemical resistance shall be expressed with letters corresponding to their values as indicated in Table 2.

A1 > 36,5 36,5 ≥ A2 > 33,0 33,0 ≥ A3 > 29,0 A4 ≤ 29,0 4.2.5 Chemical resistance C1 C2 C3 C4 C1: Agglomerated stones which keep below 60 % of the reference reflection values (see EN 14617-10) after 8 h of alkali or acid attack. C2: Agglomerated stones which keep between 60 % and 80 % of the reference reflection value (see EN 14617-10) after 8 h of alkali attack and 1 h of acid attack. C3: Agglomerated stones which keep between 60 % and 80 % of the reference reflection value (see EN 14617-10) after 8 h of acid attack and 1 h of alkali attack. C4: Agglomerated stones which keep at least 80 % of the reference reflection value (see EN 14617-10) after 8 h of acid or alkali attack (or in one case, see EN 14617-10, is between 60 % and 80 %).
4.2.3 Flexural strength The values for flexural strength of modular tiles shall always be declared. The flexural strength shall be determined using the test method in EN 14617-2 and the results expressed accordingly. The classification of flexural strength of modular tiles is given in Table 2. 4.2.4 Abrasion resistance Where subject to contractual request or where the product is expected to be subject to aggressive abrasion actions, the values for abrasion resistance of modular tiles shall be declared. The resistance to abrasion shall be determined using the test method in EN 14617-4 and the results expressed accordingly. The classification of abrasion resistance of modular tiles is given in Table 2. 4.2.5 Chemical resistance Where subject to contractual request or where the product is expected to be subject to aggressive chemical actions, chemical resistance of modular tiles shall be declared.

4.2.9 Slipperiness The value for slipperiness of modular tiles shall be declared when subject to regulatory requirements and may be declared otherwise. The slipperiness shall be determined using tests methods in EN 14231 and the results expressed accordingly.
