The colour, roughness etc. of the agglomerated stone shall be identified visually (see 4.2.7) e.g. by a range of samples selected in agreement by manufacturer and purchaser following the criteria given in EN 14617-16. Any visual variations, for example inclusions and veins, are permissible provided that they are characteristic of the relevant type of agglomerated stone and provided that they do not adversely affect the performance of the tiles. Reference samples are described in 4.2.7. 4.2.7 Reference sample, visual inspection and acceptance criteria A reference sample shall be an adequate number of pieces of agglomerated 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. Evaluation of the reference sample does not imply strict uniformity between the sample itself and the actual supply; natural variations in tonality can always occur due to natural raw materials. All the differences in aesthetical pattern between the tiles and the reference sample shall be considered typical of the agglomerated stone and not as flaws. Therefore they shall not become a reason for rejection, unless their presence exceeds 15 % of the surface and the typical pattern of the agglomerated stone is lost. Any comparison between production tile and reference sample shall be carried out by placing the reference sample in a vertical position against the production tile, viewing them at a distance of about two metres under normal daylight conditions and recording any visible differences in the characteristics of the agglomerated stone (see Figure 2). According to this method the shading tolerance and the gloss value (in the case of fine ground, honed or highly polished surfaces) measured at six different points of the tile shall be evaluated. Any features of tiles which are likely to adversely affect the flexural strength and the structural stability of the agglomerated stone, such as cracks, hairline cracks, cavities, soft inclusions or similar, are not permitted if the modular tiles are intended to be mechanically fixed. The name and address of the manufacturer or supplier of the agglomerated stone, shall also be indicated on the reference test sample. NOTE The pieces of agglomerated stone should be analysed under similar conditions: e.g. wet/dry, light. 4.2.8 Reaction to fire Reaction to fire performance shall always be declared when the modular tiles are intended to be used in areas subjected to reaction to fire regulation and may be declared otherwise.
EN 15285:2008 (E) 9 Agglomerated stones (except those containing more than 1 % by mass or volume, whichever is the most onerous, of organic materials), may be classified without testing (CWT) as reaction to fire Class A1fl 1). For agglomerated stones containing more than 1 % by mass or volume, whichever is the most onerous, of organic materials, and having an end use subject to reaction to fire regulatory requirements shall be tested and classified in accordance with EN 13501-1.

The tactility is expressed by a description of surface corrugation obtained by mechanical finishing. NOTE The characteristic "tactility", when requested, is covered by the description of the morphology of the surfaces. "Visibility" has been considered as not relevant for agglomerated stones, because, when a particular visibility is needed, it is not normally achieved using this product. 4.2.13 Linear thermal expansion coefficient Where subject to contractual request or where the modular tiles are expected to be subject to relevant dimensional variations due to temperature changes, linear thermal expansion coefficient of modular tiles shall be declared. The linear thermal expansion coefficient shall be determined using the test method in EN 14617-11 and the results expressed accordingly. 4.2.14 Electrical resistivity Where subject to contractual request, electrical resistivity of modular tiles shall be declared. The electrical resistivity shall be determined using the test method in EN 14617-13 and the results expressed accordingly. 4.2.15 Impact resistance Where subject to regulatory requirements or where the product is expected to be subject to impact of hard falling objects, impact resistance of modular tiles shall be declared. The impact resistance shall be determined using the test method in EN 14617-9 and the results expressed accordingly. 4.2.16 Frost resistance Where subject to regulatory requirements or where the product is expected to be subject to freeze/thaw cycles, frost resistance of modular tiles shall be declared.
EN 15285:2008 (E) 11 The frost resistance shall be determined using the test method in EN 14617-5 and the results expressed accordingly. 4.2.17 Dimensional stability Where subject to regulatory requirements or where the product is expected to be sensitive to the adhesive used for installation, dimensional stability of modular tiles shall be declared. The dimensional stability shall be determined using the test method in EN 14617-12 and the results expressed accordingly. 5 Marking, labelling and packaging As a minimum of identification, each consignment shall specify on the label and/or packaging the denomination of the agglomerated stone (see EN 14618). The dimensions, quantities and/or any other information shall be reported on the accompanying documents. The number of labels shall be sufficient to identify the delivered products according to the type of packaging. The modular tiles shall be clean before packaging and transporting. Sensitive polished surfaces shall be protected by appropriate means. Tiles which are susceptible to stains shall get special attention in order to protect them. Packing and tapes which are likely to stain shall not be used. Products with caustic properties shall not be used. 6 Evaluation of conformity 6.1 General rules The compliance of agglomerated stone modular tiles with the requirements of this European Standard and with the declared values shall be demonstrated by initial type testing and additionally the manufacturer shall exercise a permanent factory production control and register the results. 6.2 Initial type testing (ITT) Initial type testing of a modular tiles made of agglomerated stone product, as given in Table 3, shall be carried out: a) to demonstrate conformity to this European Standard or at the beginning of production of a new material, b) when significant variations occur in the production process, determined visually or by significant changes in FPC results.
