EN 1467:2012 (E) 5 1 Scope This European Standard specifies requirements for rough blocks of natural stone from which products for use in building 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 block size which is obtained by reducing each net dimension by 0,05 m (see Figure 1) SIST EN 1467:2012



EN 1467:2012 (E) 6 Dimensions in metres
Key _._._._ gross size --------- commercial size Figure 1 — Gross sizes, commercial sizes of a rough block 3.2 dimensions of a rough block length l, width b and height h are the dimensions of a squared rough block. They are given in the stated sequence in meters to two decimals places 3.2.1 length l greater side in a natural layer where appropriate 3.2.2 width b smaller side in the natural layer or at right angles to length 3.2.3 height h side at right angles to the natural layer (see Figure 2) or to the plane containing length l and width b SIST EN 1467:2012



EN 1467:2012 (E) 7
Key 1 natural layer Figure 2 — Dimensions of a rough block 3.3 gross size of the rough block size defined by the lengths of the edges of the smallest parallelepiped circumscribed to a rough block (see Figure 1) 3.4 net size of a rough block size which is determined in the following manner: Establish the greatest inscribed parallelepiped block which shall not contain any sides without right angles nor contain drill holes and other holes. The resulting figure is the net size 3.5 rough block basis of the usable stone consisting of rocks obtained directly from quarries or erratics with no processing whatsoever except extraction and shaping by cutting or splitting 3.6 rough block of specific size squared rough block with certain given dimensions 3.7 shapeless rough block rough block without regular shape and size 3.8 squared rough block rough block which corresponds approximately to a regular parallelepiped Note 1 to entry: Normally the ratio obtainable by dividing the mass of the squared rough block by the apparent density should be bigger than 80 % of the gross size. If such a ratio is equal to or less than 80 %, the block is considered a shapeless 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. SIST EN 1467:2012



EN 1467:2012 (E) 8 4.1.2 Requirements on shape The six sides of squared rough block shall be approximately flat, right-angled and parallel, and correspond to the shape of a parallelepiped. Local deviations from the parallelepiped shape are permitted. Shapeless rough blocks for commercial purposes are only measured by mass, (see 4.1.4); gross size shall be provided upon request. Rough blocks of specific size shall have dimensions not lower than the minimum values and not greater than the maximum values agreed between the purchaser and supplier. 4.1.3 Requirements for volume The volume of a rough block shall be stated in cubic metres to three decimals places. The volume may be calculated by dividing the mass of the block by the apparent density. 4.1
