Standards

On a national and international level, there are several normalized tests that test the specific properties of natural stone. Additionally, there are standards that set forth minimum criteria to be met by, for instance, natural stone if used for external paving. Here comes a selection:

Méthodes d'essai européennes sur pierre naturelle

Standard Title
NBN EN 1925 Determination Of Water Absorption Coefficient By Capillarity
NBN EN 1926 Determination of uniaxial compressive strength
NBN EN 1936 Determination of real density and apparent density, and of total and open porosity
NBN EN 12371 Determination of frost resistance
NBN EN 12372 Determination of flexural strength under concentrated load
NBN EN 12407 Petrographic examination
NBN EN 14231 Determination of the slip resistance by means of the pendulum tester
NBN EN 14066 Determination of resistance to ageing by thermal shock
NBN EN 14157 Determination Of Abrasion Resistance

Furthermore, there is a whole series of standards defining the minimum requirements for natural stone used in specific applications, together with their testing methods. A selection of these standards is listed below:
