EN 12059:2008 (E) 4 1 Scope This European Standard specifies requirements for the following stone units:
a) Structural solid stone units: i. Load bearing stone elements, typically subject to prevailing compression stresses, such as solid columns, arches and similar; ii. Solid stone elements used for parapets, handrails, balustrades, copings and the like, intended to withstand horizontal live loadings in addition to any dead load. b) Finishing solid stone units: i. Curved cladding panels, for the external finishing of walls, columns or pilasters; ii.

EN 12059:2008 (E) 5 NOTE Besides the European Standards for test methods mentioned in this clause there exist further standards which can be used for scientific examinations, but which are not relevant for the application in practice according to this standard. 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 12670:2001 and the following apply. 3.1 dimensional stone work stone element worked to any specific dimensions for inside or outside application in the building sector NOTE Dimensional stone work includes: flat stone elements which are not used as slabs for cladding, (see EN 1469) or slabs for floors and stairs (see EN 12058) and also for furniture (e.g. tables, kitchen tops);
curved stones or three-dimensional shaped stone elements. 4 Requirements 4.1 Requirements for geometric characteristics 4.1.1 General The dimensions shall be as given in the appropriate design drawings. All measurements shall be carried out in accordance with EN 13373 and all measured values of individual units shall fall within the required tolerances. 4.1.2 Requirements for thickness The thickness shall not deviate from the nominal thickness by more than the tolerances given in Table 1. Table 1 — Tolerances on the nominal thickness Nominal thickness in mm
Tolerance
More than 15 up to and including 30 ± 10 % a More than 30 up to and including 80 ± 3 mm b More than 80 ± 5 mm c a in case of elements to be assembled the tolerance of the visual thickness shall become respectively ± 0,5 mm b in case of elements to be assembled the tolerance of the visual thickness shall become respectively ± 1 mm c in case of elements to be assembled the tolerance of the visual thickness shall become respectively ± 2 mm
Stricter tolerances may be declared by the supplier. The required thickness of the stone elements shall result from a structural analysis or similar procedure which takes into account the technical and physical properties of the stone and the intended application. For natural cleft/riven faces, Table 1 does not apply and the tolerances shall be declared by the supplier.
EN 12059:2008 (E) 6 4.1.3 Requirements for flatness The deviation from flatness of the surface (except for natural cleft faces) shall not exceed 0,2 % of the length, and shall not exceed 3 mm. For natural cleft faces, the tolerance on flatness shall be declared by the supplier. 4.1.4 Requirements for length and width The length or width shall not deviate from the nominal size by more than the tolerances given in Table 2. Table 2 — Tolerances on length and width Nominal length or width in mm < 600 ≥600 Sawn edges thickness ≤80 mm ± 2 mm ± 3 mm Sawn edges thickness > 80 mm ± 4 mm ± 5 mm
Stricter tolerances may be declared by the supplier. 4.1.5 Requirements for angles and special shapes The permissible tolerance at any point shall be as stated in Table 2. Each slab angle shall be in accordance with the agreed geometry. Pieces of special or irregular shape (e.g. curved) shall be checked for compliance with the required shape by use of a suitable template, the permissible tolerance at any point shall be as stated in Table 2. In cases where the thickness of a curved unit is both greater than and less than 80mm at different parts of the unit, the tolerance shall always be that for less than 80mm.
Stricter tolerances may be declared by the supplier. 4.1.6 Requirements for edges Normally all edges shall be chamfered, unless specified differently. 4.1.7 Requirements for surface finish 4.1.7.1 General Surface finishes shall extend uniform to the edges of the stone element on all treated sides. The surface finishing of some types of stones may typically involve the use of patching, fillers or other similar products for natural holes, faults or cracks: this is to be considered as part of the normal processing. In such cases the type of treatment as well as the type and nature of additional materials shall be declared. Surface finishes shall be suitable for the intended use. 4.1.7.2 Requirements for surfaces after finishing Surfaces shall have a regular appearance according to the finishing process and shall be worked to meet the specified finish (e.g. making reference to samples, see 4.2.2) on all exposed surfaces. NOTE 1 Surfaces obtained by grinding are, for example: rough ground surfaces obtained, e. g. by means of a grinding disk of grain size F 60;
EN 12059:2008 (E) 7 medium ground surfaces obtained, e. g. by means of a grinding disk of grain size F 120; fine ground surfaces obtained, e. g. by means of a grinding disk of grain size F 220; matt finished surfaces obtained, e. g. by means of a polishing disk with grain size F 400; highly polished surfaces obtained, e. g. by means of a polishing disk or felt. NOTE 2 Surfaces obtained by means of hammer type tools are, for example: bush hammered surfaces (see EN 12670:2001, 3.3.8)*; trimmed surfaces: finish obtained by using pointed chisel and mallet or a grooving machine; striated surfaces: finish obtained by using a claw chisel (percussion tool for roughening a surface, with the cutting end covered by several teeth of various size) or a ruling machine. NOTE 3 Surfaces obtained by other finishing operations are, for example: flamed finish (see EN 12670:2001, 3.3.22)**; sand blasted finish (see EN 12670:2001, 3.3.46)***; water jet streamed finish: a matt textured surface finish, accomplished by exposing the surface to a steady jet of water under pressure; machine tooled finish (see EN 12670:2001, 3.3.54)****; riven cut finish: rugged surface produced by splitting the stone with a guillotine or chisel. * finish obtained by using a bush hammer (percussion tool for roughening a surface, with a square head and with few pyramidal percussion teeth or points) or a bush hammering machine (machine consisting of feed rolls and a overhanging beam, supporting a pneumatic bush hammer). ** surface texture obtained by thermal treatment of the stone using a high temperature flame. *** a matt finish resulting from the impact of sand or other abrasive grains expelled by a sand jet. **** this term has two different meanings: 1) finish resulting from the mechanical surface treatment with tools;
2) dressed finish clearly showing tool marks. 4.2 Requirements of natural stone for dimensional work 4.2.1 General Due to the natural variations of the stone materials, deviations from the declared values can occur. Whenever stone processing is likely to change the characteristics of the initial material (e.g. as a consequence of the type of processing or because the use of patching, fillers or other similar products for natural holes, faults, cracks and similar), then this has to be considered when determining the characteristics requested by this standard. The following characteristics shall be declared where requested by this standard or with reference to the intended use conditions.
EN 12059:2008 (E) 8 4.2.2 Denomination The denomination shall always be declared in accordance with EN 12440 (it means traditional name, petrological family, typical colours and place of origin). The petrographic name shall be determined in accordance with EN 12407. 4.2.3 Visual appearance This characteristic shall always be declared. The colour, veining, texture, etc. of the stone shall be identified visually, typically by a reference sample of the same stone suitable t
