for tests on natural stone. test methods for natural stone consist of the following parts:en 1925natural stone test methods determination of water absorption coefficient by capillarity.en 1926natural

(nevertheless it is not intended that all natural stones products should be subjected regularly to all the listed tests. specifications in other standards should call up only relevant test methods).according to the cen/cenelec internal regulations, the national standards organizations of the following countries are bound to implement this european standard: austria, belgium, czech republic, denmark, finland, france, germany, greece, iceland, ireland, italy, luxembourg, netherlands, norway, portugal, spain, sweden, switzerland and the united kingdom.licensed copy: sheffieldun
