EN 1468:2012 (E) 5 1 Scope This European Standard specifies requirements for rough slabs of natural stone from which products for use in buildings or commemorative stones and other similar applications are made.
It does not cover artificially agglomerated stony material nor installation. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 1936, Natural stone test methods - Determination of real density and apparent density, and of total and open porosity EN 12372, Natural stone test methods — Determination of flexural strength under concentrated load EN 12407, Natural stone test methods — Petrographic examination EN 12440, Natural stone — Denomination criteria EN 12670:2001, Natural stone — Terminology EN 13161, Natural stone test methods — Determination of flexural strength under constant moment EN 13373, Natural stone test methods — Determination of geometric characteristics on units 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 European 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 commercial size of a rough slab size obtained by reducing net length and net width by 0,03 m 3.2 dimensions of a rough slab length, width (height) and thickness of a rough slab Note 1 to entry: Dimensions are given in metres to two decimals places for length and width, and in millimetres for thickness. 3.3 gross size of a rough slab size corresponding to the minimum circumscribed rectangle 3.4 net size of a rough slab size corresponding to the greatest inscribed rectangle SIST EN 1468:2012
EN 1468:2012 (E) 6 3.5 rough slabs flat surface semi-finished product with unfinished edges obtained by sawing or splitting from a rough block 4 Requirements 4.1 Requirements for geometric characteristics 4.1.1 Measurement criteria All measurements shall be carried out in accordance with EN 13373 and indicated in metres to two decimals places. 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 of the nominal thickness Nominal thickness Tolerance mm
up to 15 ± 1,5 mm more than 15 up to and including 30 ± 10 % more than 30 up to and including 80 ± 3 mm more than 80 ± 5 mm
Stricter tolerances may be declared by the manufacturer. For natural stone cleft/riven faces, the tolerances on thickness shall be declared by the manufacturer. 4.1.3 Requirements for flatness The deviation of the surface from flatness shall not exceed 0,2 % of the slab length and shall not exceed 3 mm. For split rough slabs, the tolerance on flatness shall be declared by the manufacturer. Stricter tolerances may also be declared by the manufacturer. 4.1.4 Requirements for surface finish 4.1.4.1 General Surface finishes shall be carried out at least to the edges of the commercial size of rough slabs. 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, and 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. The surface profile obtained by splitting shall be within declared tolerances. SIST EN 1468:2012
EN 1468:2012 (E) 7 4.1.4.2 Requirements for surfaces obtained by sawing Grooves caused by sawing operations shall not have a depth greater than 2 mm. If the rough slab is to be polished, the grooves' depth shall not be greater than 1 mm.
Deviation from flatness shall be in accordance with 4.1.3. 4.1.4.3 Requirements for surfaces after surface finishing Surfaces shall have a regular appearance as a function of 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 means of hammer type tools are, for example: bush hammered surfaces (see EN 12670:2001, Definition 2.3.8 1)); trimmed surfaces: finish obtained by using a 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 sizes) or a ruling machine. NOTE 2 Surfaces obtained by other finishing operations are, for example: flamed finish (see EN 12670:2001, Definition 2.3.22 2)); sand blasted finish (see EN 12670:2001, Definition 2.3.46 3)); 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, Definition 2.3.54 4)); riven cut finish: rugged surface produced by splitting stone with a guillotine or chisel. 4.2 Requirements of natural stones for rough slabs 4.2.1 General The following characteristics shall be declared where requested by this European Standard, or with reference to use conditions. The declared values shall be representative of the current production. However, due to natural variations of the stone materials, deviations from the declared values may occur. Expec
