Modulus of Rupture of Refractory Products - Test Method - BS EN 993-6:1995, BS 1902-4.4:1995


Methods of test for dense shaped refractory products. Determination of modulus of rupture at ambient temperature.


Modulus of rupture is the maximum stress that a prismatic test piece of specified dimensions can withstand when it is bent in a three-point bending device.


Loading of test pieces of the product to be tested at a constant rate of increase of stress until failure occurs.
