GB/T 44752-2024 specifies the bending fatigue test method for flexible glass, primarily employing the planar unidirectional two-point bending method. It is applicable for evaluating the durability performance of flexible glass used in foldable screens and wearable devices under repeated bending, determining its fatigue life and failure modes. The standard defines requirements for sample preparation, test parameters, and operational procedures, simulating actual bending conditions in practical use. The test requires the use of a bending fatigue testing machine (controlling plate spacing and cycle frequency), a device for characterizing bending curvature radius, along with an environmental chamber (for temperature and humidity control), a high-resolution microscope, and precision cutting/grinding equipment to ensure reliable test results. This provides a unified technical basis for quality control and product design of flexible glass.
