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, i
23、ntended 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. Stone elements for framing one or more side openings in building walls or floors, such as sills, jambs
24、, architraves and similar. This European Standard does not include stone masonry units, as defined in EN 771-6, stone which is a cast-on finish to pre-cast concrete or agglomerated stones. Moreover it does not cover commemorative or funeral stones and sculptures, when they do not show the above ment

32、ork 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 characte
33、ristics 4.1.1 General !The dimensions shall be given in the appropriate design drawings indicating e.g. thickness, length and width.“ 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 Require
34、ments 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 % aMore than 30 up to and including 80 3 mm bMore than 80
35、5 mm cain case of elements to be assembled the tolerance of the visual thickness shall become respectively 0,5 mm bin case of elements to be assembled the tolerance of the visual thickness shall become respectively 1 mm cin case of elements to be assembled the tolerance of the visual thickness shall
36、 become respectively 2 mm Stricter tolerances may be declared by the supplier. DIN EN 12059:2012-03 EN 12059:2008+A1:2011 (E) 6 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
37、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. 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 sh
38、all 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
39、length or width in mm 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 irre
40、gular 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,
41、 the tolerance shall always be that for less than 80mm. Stricter tolerances may be declared by the supplier. 4.1.6 Requirements for edges !Indicate whether the edges are chamfered.“ 4.1.7 Requirements for surface finish 4.1.7.1 General Surface finishes shall extend uniform to the edges of the stone
42、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
43、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. mak
44、ing reference to samples, see 4.2.2) on all exposed surfaces. DIN EN 12059:2012-03 EN 12059:2008+A1:2011 (E) 7 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; medium ground surfaces obtained, e.g. by means of
45、 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 Su
46、rfaces 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
47、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 textur
48、ed 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
49、 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. *
