European foreword
This document (EN 1467:2022) has been prepared by Technical Committee CEN/TC 246 “Natural
stones”, the secretariat of which is held by UNI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by April 2023, and conflicting national standards shall be
withdrawn at the latest by April 2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 1467:2012.
The main technical changes in comparison to EN 1467:2012 are:
— new definition of the commercial size of a rough block in 3.4;
— measurement criteria for the commercial size changed;
— requirements for the Factory Production Control (FPC), including specimens for testing, are
presented in greater detail in 6.3.1.
This document is one of a series of standards for requirements of natural stone products which includes
the following:

Note 2 to entry: For shapeless rough blocks for commercial purposes, see also 4.1.2 and 4.1.4.
3.3
net size of a rough block
size which is determined by establishing the greatest inscribed cuboid block (see Note)
Note 1 to entry: The inscribed cuboid block shall not contain any sides without right angles nor contain drill holes
and other holes; the resulting size represents the net size.
3.4
commercial size of a rough block
size obtained by reducing each net size dimension
Note 1 to entry: See Figure 2.
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 cuboid
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. The commercial size of a rough block refers either to gross or net size and excluding
recognized defects and it may allow for a general reduction for commercial purpose only, usually net size
dimensions minus 0,05 m (see Figure 2).
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 cuboid. Deviations from the cuboid 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.
4.1.4 Requirements for mass
The mass of a rough block shall be stated in tonnes with three decimals. For commercial purposes,
shapeless rough blocks shall be measured only by mass, gross size shall be provided upon request.
4.2 Requirements of natural stone for rough blocks
4.2.1 General
The following characteristics shall be declared where requested by this document, 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. Expected deviations shall be
indicated by the manufacturer.
In case of layered stone: If a rough block contains different types of stones (see 4.2.2) all characteristics
shall be declared.
In case of highly heterogeneous and anisotropic lithotypes, see 4.2.2, all characteristics shall be declared.
4.2.2 Denomination
The denomination (traditional name, petrological family, typical colour and place of origin) shall always
be declared in accordance with EN 12440.
NOTE The place of origin can be given by GPS coordinates.
The petrologic definition shall be determined in accordance with EN 12407.
4.2.3 Visual appearance
This characteristic shall be declared upon request.
The colour, veining, texture, etc. of the stone shall be identified visually (for example by a polished
reference sample). The reference samples shall be provided by the supplier.
Any visual variations, for example inclusions and veins, are permissible, provided that they are
characteristic of the relevant type of natural stone a
