EN 1343:2012 (E) 9 4 Requirements and test methods for slabs of natural stone
4.1 Introduction 4.1.1 General Unless otherwise stated, kerbs shall be supplied in free running lengths. For curved kerbs the length is the measured visible face circumference. The manufacturer shall state the minimum and maximum working length of a kerb unit. The ends of curved kerbs shall be radial. Curved kerbs shall be identified by the radius of the vertical visible or traffic face. The overall length of a number of curved kerbs shall be measured without the joints on the edge common to the visible faces. The minimum length of curved kerbs shall be 500 mm. Nominally square arrises may have a chamfer with vertical and horizontal dimensions not exceeding 2 mm. The dimensions of larger chamfers, radiused corners and splays, when used, shall be declared by the supplier. Examples of typical kerb cross-sections are shown in Figure 3. 4.1.2 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). 4.1.3 Alteration of physical properties of the natural stone If during production the natural stone kerbs have been subjected to a treatment that physically alters the properties of the stone (e.g. chemical treatment, patching, or filling or other similar products for natural holes, faults or cracks), then the use of such treatment shall be stated. In addition, specimens for testing shall be representative of the product and any processes that the stone is subjected to.

EN 1343:2012 (E) 12 Tolerances may not be added to each other, for example, protrusions and perpenduclarities. 4.3 Freeze/thaw resistance 4.3.1 Freeze- thaw under normal conditions
When the kerbs are intended to be used in areas subjected to 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 flexural 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  Flexural strength The flexural strength shall be determined using the test method in EN 12372 and the lower expected value (EL) shall be declared. An identification test as defined in EN 12372 is normally carried out. 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. NOTE 1 Guidance on the appropriate breaking load for different classes of use is given in Annex A. For some specific uses where a load under constant momentum is required, it may be appropriate to determine the flexural strength in accordance with EN 13161. NOTE 2 An example of the calculation used to determine the lower expected value is given in Annex C. 4.5 Appearance
4.5.1 General
The colour, veining, texture, etc. of the natural 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 according to 4.5.2. 4.5.2 Reference sample, visual inspection and acceptance criteria A reference sample shall be an adequate number of kerbs or parts of kerbs of sufficient size to indicate the general appearance of the finished work. They shall indicate the range of appearance regarding the colouring, SIST EN 1343:2013



EN 1343:2012 (E) 13 the vein pattern, the physical structure and the surface finish. In particular the reference sample shall show specific characteristics of the stone, such as holes for travertine, worm holes, glass seams, spots, crystalline veins and rusty spots. The reference sample does not imply strict uniformity between the sample itself and the actual supply; natural variations may always occur. 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. 4.6 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. 4.7 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. 4.8 Petrographic description A petrographic description shall be provided, including a petrographic name, of the stone type, in accordance with EN 12407. 4.9 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 website on EUROPA accessed through: http://ec.europa.eu/enterprise/construction/cpd-ds/. SIST EN 1343:2013



EN 1343:2012 (E) 14 5 Evaluation of conformity 5.1 General The conformity of the product (i.e. natural stone kerbs) 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. 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.
Initial type testing of the product, as given in Table 5, 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.
