Bibliography

Defines requirements for the following stone units: Structural solid stone units: - Load bearing stone elements, typically subject to prevailing compression stresses, such as solid columns, arches and similar; - Solid stone elements used for parapets, handrails, balustrades, copings and the like, intended to withstand horizontal live loadings in addition to any dead load. Finishing solid stone units: - Curved cladding panels, for the external finishing of walls, columns or pilasters; - Stone elements for framing one or more side openings in building walls or floors, such as sills, jambs, architraves and similar.
