GB/T 3002 - 2017 stipulates the test method for high temperature flexural strength of refractory materials. The standard specifies the required equipment, such as high temperature furnace, loading device, etc. The standard sample is prepared, and the specific size strip is required. During the test, the sample is placed in a high temperature environment, and the bending load is applied at a set rate until it breaks, and the load data at the time of fracture is accurately recorded. Through this method, the ability of refractory materials to withstand bending stress at high temperature can be accurately determined, which provides a key basis for production enterprises to control the mass of products and users to choose materials reasonably, and guarantees the structural Stability of refractory materials under high temperature and complex working conditions.
