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 similar 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].
