This document describes methods for verifying the geometric characteristics of products of natural stone such as rough blocks, rough slabs, finished products for cladding, flooring, stairs and modular tiles and paving units (slabs, setts and kerbs). These methods can be applied in the case of a dispute between two parties, they are not compulsory for production control.
Other measuring equipment can be used as long as their precision can be demonstrated to be equal or better than the ones mentioned here.
It is essential that all weighing, measuring and testing equipment are calibrated or retraceable to measurement standards and regularly inspected according to documented procedures, frequencies and criteria. It is important that the expression of the dimensional characteristics is in accordance with the appropriate class of the measured product.

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, 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 in 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 sculptures, when they do not show the above mentioned characteristics.

This document specifies the terminology and classification of the agglomerated stone products. Agglomerated stone products are industrial products mainly made of hydraulic cement, resin or mixture of both, stones and other additions. They are industrially manufactured in geometrical shapes at fixed plants by moulding techniques. They are put on the market in the form of rough blocks, rough slabs, slabs, tiles, dimensional stone works, and any other cut to size products.
All other agglomerated stones products not intended to be used for flooring, wall finishes and assimilated uses (like drainage channels, structural elements, etc.) are excluded from the field of this standard.
This European Standard is not applicable to terrazzo tiles covered by EN 13748-1 [1] and EN 13748-2 [2].
