What is BS EN 16515 – Stone used in cultural heritage conservation about?  
BS EN 16515 specifies a methodology for the characterization of sound or deteriorated stones by using the most appropriate analytical techniques on samples taken from the object.
BS EN 16515 contains guidelines for the selection of methods to determine mineralogical, textural, physical, chemical, and mechanical properties of natural stone used in cultural heritage monuments and objects. This information is used to define rock typology and to evaluate the stone’s condition with respect to its conservation as well as for an understanding of deterioration processes of natural stone.
BS EN 16515 is used to determine the kind, extent, and objectives of the examination to be made. Methods used for stone analysis can vary depending upon the objectives of the work. All investigation and analysis need to be proportional to the significance of the building or artifact being investigated, its condition, and the likely level of intervention.

Why should you use BS EN 16515 - Stone used in cultural heritage conservation?  
The characterization of a stone is an essential step for a conservation plan, in order to decide on appropriate remedial interventions, to achieve better working practices and technologies for conservation interventions including stone replacements. Therefore, it is important that it is achieved through a consistent and uniform methodology.
BS EN 16515 provides cultural heritage professionals with a guidance for a common methodology for the characterization of stones used in cultural heritage. This information is used to define the nature (petrography or mineralogy and texture) and properties (chemical, physical and mechanical) of stone.
The characterization of stones used in cultural heritage should be carried out and interpreted by professionals experienced in the field of materials science and/or conservation/restoration.  BS EN 16515 contributes to restore monuments to their aesthetic, cultural and historic value.
