ISO/FDIS 5013

Refractory products — Determination of modulus of rupture at elevated temperatures

General information

50.00     Jul 6, 2026

ISO

ISO/TC 33

International Standard

81.080  

Scope

Specifies a method for the determination of the refractory products at elevated temperatures, under conditions of a constant rate of increase of stress. A method for determination of the same property at ambient temperature is given in ISO 5014. The modulus of rupture is the ratio of the bending moment at the point of failure to the moment of resistance (the section modulus). It is calculated from an equation which is derived from Hooke' s Law for elastic materials.
