EH value which corresponds to the 95 %-quantile of a logarithmic normal distribution for a confidence level of 75 % 4 Requirements 4.1 General 4.1.1 Denomination The denomination shall always be declared in accordance with EN 12440 (meaning traditional name, petrological family, typical colour and place of origin as precisely as possible for example geo coordinates). 4.1.2 Alteration of physical properties of the natural stone If during production the natural stone setts have been subjected to a treatment process that physically alters the properties of the stone (for example chemical treatment, patching, or filling or other similar products for natural holes, faults or cracks) then the use of such a treatment shall be stated. In addition, specimens for testing shall be representative of the product and any processes that the stone is subjected to. 4.2 Dimensions 4.2.1 General The work dimensions of the setts shall be declared. Dimensions between faces shall be stated as a unitary nominal dimension or as a range of nominal minimum-maximum dimensions, e.g. (100 - 200) mm.
Dimensions of each shall be measured in accordance with EN 13373. 4.2.2 Tolerances 4.2.2.1 Plan dimensions and thickness Plan dimensions and thickness of a sett shall be measured in accordance with EN 13373:2003, 5.2 and 5.3 and the deviations from the declared plan dimensions and thickness shall conform to tolerances given in Table 1. Different deviations may be declared for plan dimensions and thickness. Unless stated otherwise, a consignment of setts shall be intended to be laid in rectilinear patterns and all setts within a consignment, when measured in accordance with EN 13373:2003, 5.4, shall conform with the tolerances from the plan and thickness dimensions described in Table 1.

Where a consignment of setts is specifically designated for being laid in radial or arch patterns then it may include a proportion of the total agreed by the specifier, that are bigger, smaller and trapezoidal setts not varying from the dimensions allowed by the stated tolerance by more than 10 %. When dimensions between faces are declared as a range of nominal minimum – maximum thickness, the deviation shall be declared on the limits of the range. This is particularly applicable to hewn setts. In all cases the thickness of the setts shall be observed.
4.2.2.2 Undercut of sides
When measured in accordance with EN 13373:2003, 5.5, deviations of the undercut of a side shall not exceed the tolerances given in Table 2 with respect to the perpendicularity of the upper face (see Figure 1).

4.3 Freeze/thaw resistance 4.3.1 Freeze- thaw under normal conditions
When the setts are intended to be used in areas subjected to freeze and thaw freeze-thaw requirements, the freeze/thaw resistance shall be determined using the test method in EN 12371. The results shall be expressed and declared as the mean compressive strength before and after 56 cycles of freeze/thaw (technological test). The frost damage, which a natural stone may suffer when installed, depends on the climatic conditions of the place of use, the relative position in the works (which determines the degree of saturation) and the predicted service life of the works. This number of cycles is appropriate to a specific project and may help to provide guidance for the interpretation of the test results. The selection of the stones is subjected to climatic zones and/or to codes of practice. For some specific uses, for example in locations that are subject to temperatures below - 12 °C, it may be appropriate to use different test cycles, e.g. freezing in water, freezing to a lower temperature, or testing specimens embedded in non-porous siliceous granules or a different number of cycles, e.g. the identification test as defined in EN 12371. 4.3.2 Freeze-thaw in the presence of de-icing salts
Where required, freeze-thaw resistance with the effect of de-icing salts shall be determined and declared. In the absence of a European test method, freeze-thaw resistance with the effect of de-icing salts shall be determined and declared according to national provisions valid in the place of use of the product. 4.4 Breaking strength  Compressive strength The compressive strength shall be determined using the test method in EN 1926 and the lower expected value (EL) shall be declared. 4.5 Abrasion resistance The abrasion resistance shall be determined using the test method in EN 14157 and the higher expected value (EH) shall be declared. SIST EN 1342:2013

In the absence of a European test method, skid resistance may be determined and declared according to national provisions valid en the place of use of the product. 4.6.3 Durability of slip or skid resistance When required, durability of slip and skid resistance shall be declared.
In the absence of European test methods, durability of slip and skid resistance shall be determined and declared according to national provisions valid in the place of use of the product. 4.7 Appearance
4.7.1 General 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.
A reference sample shall be provided by the supplier in accordance with 4.7.2. 4.7.2 Reference sample, visual inspection and acceptance criteria A reference sample shall be an adequate number of setts of natural stone of sufficient size to indicate the general appearance of the finished work. They 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 specific holes, glass seams, spots, crystalline veins and rusty spots. The reference samples does not imply strict uniformity between the sample itself and the actual supply; natural variations may always occur. SIST EN 1342:2013

Reference to the test method standards should be made to allow the selection of a suitable representative sample. All essential characteristics, given in bold in Table 4, for which the manufacturer declares performances, are subject to Initial Type Testing.
In addition, the need to perform Type Tests applies to all other characteristics included in Table 4, when the man
