21、011 (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,

22、 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. Stone elements for framing one or more side openings i

23、n building walls or floors, such as sills, jambs, 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

24、sculptures, when they do not show the above mentioned characteristics. 2 Normative references The following referenced documents are indispensable for the application of this document.

31、ion 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 R

32、equirements 4.1 Requirements for geometric characteristics 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

33、 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 % aMore

34、 than 30 up to and including 80 3 mm bMore than 80 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 as

35、sembled the tolerance of the visual thickness shall become respectively 2 mm Stricter tolerances may be declared by the supplier. BS EN 12059:2008+A1:2011EN 12059:2008+A1:2011 (E) 6 The required thickness of the stone elements shall result from a structural analysis or similar procedure which takes

36、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. 4.1.3 Requirements for flatness The deviation from flatness of the surface (except for natural cle

37、ft 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 Ta

38、ble 2. Table 2 Tolerances on length and width Nominal 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 accordan

39、ce 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 t

40、han 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 !Indicate whether the edges are chamfered.“ 4.1.7 Requirements for surface finish 4.1.7.1 General Surface fi

41、nishes 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 processin

42、g. 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

43、shall be worked to meet the specified finish (e.g. making reference to samples, see 4.2.2) on all exposed surfaces. BS EN 12059:2008+A1:2011EN 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 siz

45、ned, 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

46、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

47、: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.

48、* 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 obtai

49、ned 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 mark
