Modulus of Rupture

The Modulus of Rupture (MOR) indicates the material bending strength and its suitability for use in construction. It depicts the strength of the bonding system of the refractory product, and is an important parameter for quality control and development of refractory linings.

For the test a rectangular test sample is supported in span. The testing machine applies a load at a specific rate to the centre of the sample until it breaks. The modulus of rupture is calculated using the load at which the sample failed, the span between the support, and the cross section of the sample.

The EN   993-6 Standard is issued in 1995 and is based on the PRE/R21 elaborated in 1973.
