GB/T 45763-2025 "Fine ceramics - Test method for flexural strength of ceramic sheets at room temperature - Three-point or four-point bending method" specifies the test method for the flexural strength of fine ceramic sheets at room temperature. This standard applies to homogeneous bulk ceramics and certain ceramic matrix composites with thicknesses ranging from 0.2 mm to 1.0 mm, primarily for material development, performance characterization, and quality control. The standard test principle involves using a universal material testing machine equipped with dedicated three-point or four-point bending loading fixtures to measure the maximum load at material fracture and calculate the flexural strength. This method provides a unified and standardized testing basis for evaluating the core mechanical properties of fine ceramic sheets.
