The more compact grained and heavier a stone the harder it is. Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 30-40%. Being dry stones allow more crushing strength than when wet. It is the ability of a stone to endure and maintain its essential and distinctive characteristics i.e. resistance to decay, strength and

In Europe, the standard for the test is EN 1926 and in America ASTM C170. Both tests are essentially the same although the European test asks for larger pieces of stone to be tested. The European test also includes a statistical calculation so that natural variation is taken into account and the results lowered accordingly.
