4 Materials
4.1 General
4.2 Materials of natural stone
Natural stone is a natural product obtained by mining or by quarrying and made into masonry units by
a manufacturing process.
The following groups of materials are considered as natural stone:
Magmatic or igneous rocks: Rocks formed by the cooling and solidification of the magma, e.g.
granite, basalt, diorite, porphyry.
Sedimentary rocks: Rocks formed by deposition (generally in water) and consolidation of
organic or inorganic particles. For example limestone, sandstone, travertine.
Metamorphic rocks: Transformed rocks resulting from action of heat and/or pressure on the pre-
existing rocks. For example slate, gneiss, quartzite, marble.
5 Requirements for natural stone masonry units
5.1 General
The requirements and properties specified in this European Standard shall be defined in terms of the
test methods and other procedures referred to in this European Standard.
It should be noted that the test methods are not always applicable to specially shaped and accessory
units as defined in 3.9 and 3.10.
The conformity criteria given in the following subclauses relate to initial type tests (see 8.2) and to
consignment testing (see Annex A). For the compressive strength of Category I units use a 50 %
fractile (p = 0,50) for mean values or 5 % fractile (p = 0,05) for characteristic values and a confidence
level of 95 %.
For production evaluation the manufacturer shall define the conformity criteria in the factory
production control documentation (see 8.3).
5.2 Denomination
The denomination shall be declared in accordance with EN 12440 (meaning traditional name,
petrological family, typical colour and place of origin).
The petrographic name shall be declared in accordance with EN 12407.
5.3 Dimensions and tolerances
5.3.1 Dimensions
The dimensions of a natural stone masonry unit shall be declared (by the manufacturer/supplier) in
mm for length, width and height in that order. They shall be given in terms of work size and in addition
the coordinating size may be given. The assembly dimensions may also be given.
