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



EN 1342:2012 (E) 10 4.6 Slip and skid resistance 4.6.1 Slip resistance The slip resistance shall be declared when the intended use of the setts is subject to regulatory requirements, or upon request, and, in any case, when the roughness of the surface, measured following EN 13373:2003, 5.3, is less than 1,0 mm. The slip resistance shall be determined and the results expressed in accordance with the test procedure for both wet conditions in EN 14231. Coarse textured and hewn setts are assumed to give satisfactory slip resistance. They cannot be reliably tested. It should also be noted that the performance of setts when laid may have a different slip resistance value to that determined on individual setts or test specimens. NOTE 1 The unpolished slip resistance value relates to setts as manufactured and helps to ensure adequate slip/skid resistance on installation. NOTE 2 Experience has indicated that a USRV measurement made using a wide slider / full swing on a pendulum in wet conditions that is greater than 35 can usually be considered acceptable for surfaces that are horizontal or sloping at less than 6 %. 4.6.2 Skid resistance Where required, skid resistance shall be declared.
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



EN 1342:2012 (E) 11 If the processing of the stone involves the use of patching, fillers or other similar products for natural holes, faults or cracks, then the reference sample shall similarly display the impact of the same on the finished surface. All the characteristics as shown by the reference sample shall be considered typical of the stone and not as flaws, therefore they shall not become a reason for rejection, unless their concentration becomes excessive and the typical character of the stone is lost. The name and address of the manufacturer or the supplier of the stone, as well as the denomination of the stone in accordance with 4.1 and/or information on the treatment in accordance with 4.1.2, above, shall be indicated on the reference sample. Any comparison between production sample and reference sample shall be carried out by placing the reference sample against the production samples and viewing them at a distance of about 2 m under normal daylight conditions and recording any visible differences in the characteristics of the stones. 4.8 Water absorption Where required the water absorption shall be determined using the test method in EN 13755 and the higher expected value (EH) shall be declared. 4.9 Apparent density and open porosity The apparent density and open porosity shall be determined using the test method in EN 1936 and the mean values declared. 4.10 Petrographic description A petrographic description shall be provided, including a petrographic name, of the stone type, in accordance with EN 12407. 4.11 Dangerous substances National regulations on dangerous substances may require verification and declaration on release, and sometimes content, when construction products covered by this standard are placed on those markets. In the absence of European harmonised test methods, verification and declaration on release/content should be done taking into account national provisions in the place of use. NOTE An informative database covering European and national provisions on dangerous substances is available at the Construction web site on EUROPA accessed through: http://ec.europa.eu/enterprise/construction/cpd-ds/. 5 Evaluation of conformity 5.1 General The conformity of the product (i.e. natural stone setts) to the requirements of this standard and with the declared performances (e.g. values, classes) for the characteristics relevant for the intended use of the product, shall be demonstrated by: a) initial type testing,
b) factory production control by the manufacturer, including product assessment. SIST EN 1342:2013



EN 1342:2012 (E) 12 For the purposes of testing, the products may be grouped into product families, where it is considered that the results for one or more characteristics from any product within the family are representative for the same characteristics for all products within that family. A product may be in more than one family for different characteristics. 5.2 Initial type testing (ITT) and Type testing (TT) Initial type testing and type tests, if any, shall be performed for all characteristics included in this standard for which the performances are to be declared:  when a new product type is developed (and before it is placed on the market) or  at the beginning of a new or modified method of production where this may affect the declared performances. The declared performances should be representative of the current production, e.g. the lower expected value in normal production. Whenever a significant change occurs in the raw material or the production process, which could change any of the declared performance of the product, this shall be considered as a new product and any of such characteristic shall be re-assessed for a new declared performance.
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 manufacturer claims compliance, unless the standard gives provisions (e.g. use of previously existing data, CWFT and conventionally accepted performance) for declaring performances without performing tests. Initial type testing of the product, as given in Table 4, shall be carried out on:  first application of this document or at the beginning of the production with a new type of stone;  when significant variations occur in the material, determined visually or by significant changes in FPC results. Tests previously performed in accordance with the provisions of this document (i.e. same type of stone, same characteristic measured with the same test method, same sampling procedure and system of attestation of conformity) may be taken into account for the purpose of ITT.
