BS EN 14158 is a European Standard that covers natural stone testing methods used for both internal and external surfaces of constructions. The main aim of BS EN 14158 is to offer the best industry practices that demonstrate the quality and durability of the natural stones used for your civil engineering works.
BS EN 14158 specifies a method for determining the energy of rupture by the impact of natural stones.
BS EN 14158 contains provisions for both an identification test and a technological test (for FPC of finished products).
BS EN 14158 on the rupture energy of natural stones is useful for:
Rupture energy is the energy required to change a unit area of a fracture surface from its initial unloaded state to a state of complete separation. The energy of rupture by impact of natural stone is determined by the dropping of a spherical steel ball from given increasing heights until the test specimen breaks.
In this regard, BS EN 14158 provides the requirements of apparatus, test sampling, test method and procedure to evaluate the rupture energy of the natural stone.
As a result, complying with BS EN 14158 can help demonstrate the performance and durability of natural stones, thus determining whether or not they are fit for purpose.
