This standard specifies a unified method for determining the flexural strength of shaped and unshaped refractory materials at room temperature. Its core principle involves using the three-point bending method, where a constant loading rate is applied to a bar-shaped specimen until it fractures, thereby calculating the material's ability to resist bending moments. The key testing instrument required for conducting this test is a universal material testing machine, equipped with a dedicated three-point bending test fixture to ensure the consistency and accuracy of measurement results. This test is crucial for evaluating the mechanical properties of refractory materials at room temperature and for quality control of the products.
