ActiveRefractory products—Determination of stress-strain (three-point bending method）
耐火材料 应力应变试验方法(三点弯曲法)
Application Summary AI generated
This standard specifies a three-point bending method for determining the stress-strain behavior of refractory products. It is applied in the ceramics and glass industries to evaluate the mechanical performance and deformation characteristics of refractory materials under load. The test is critical for quality control and material selection in high-temperature applications such as kiln linings, furnace construction, and glass melting tanks.
