Modulus of Rupture and Breaking Strength of Ceramic Tiles - Test Method - BS EN ISO 10545-4:2014
Title
Ceramic tiles. Determination of modulus of rupture and breaking strength.
Overview
Determination of the breaking load, breaking strength and modulus of rupture of a tile by applying a force at a specified rate to the centre of the tile, the point of application being in contact with the proper surface of the tile.
The breaking load is the force necessary to cause the test specimen to break, as read from the pressure gauge.
The breaking strength is the force obtained by multiplying the breaking load by the ratio (span between the support rods / width of the test specimen).
The modulus of rupture is the quantity obtained by dividing the calculated breaking strength by the square of the minimum thickness along a broken tile edge.
