ActiveTest method for fracture toughness of carbon materials
炭素材料断裂韧性测定方法
Application Summary AI generated
This standard specifies the test method for determining the fracture toughness of carbon and graphite materials, covering specimen preparation, loading procedures, and data analysis. It is applied in the electrical engineering and metallurgical industries for quality control and material selection of carbon-based components, such as electrodes, brushes, and structural parts, where resistance to crack propagation under mechanical stress is critical. The method is used in laboratory testing contexts to evaluate material performance for high-temperature and high-stress applications.
