Verification of two national standards for ultrasonic total focusing technique testing

Standard verification is an effective means to ensure the scientificity, normativeness, applicability and timeliness of national standards and improve the quality of national standards. This paper introduced and analyzed the verification content of two released national standards for total focusing technique ultrasonic testing, and carried out experimental verification from the perspective of TFM equipment, image display and actual detection to improve the practicality, rationality and scientificity of the standard, and ensure the effective implementation of the standards.
