GB/T 44525-2024 "Non-destructive testing - Ultrasonic testing - Specification for reference blocks for resin matrix composite products" specifies the design, manufacturing, performance requirements, and inspection methods for reference blocks used in ultrasonic testing of resin matrix composites. It clarifies the material, dimensional tolerances, types of artificial reflectors (such as flat-bottom holes and side-drilled holes) and their arrangement, and defines acoustic performance indicators and appearance quality requirements. This standard is applicable to the calibration and sensitivity adjustment of ultrasonic testing for resin matrix composite products, such as carbon fiber and glass fiber composites, providing technical support for the accuracy and consistency of inspection results.
