Abstract: The types of phased array ultrasonic testing instruments are growing in recent years with the development of the phased array inspection technology. In order to better understand the performance of the phased array instrument, the performance test and evaluation standards of phased array testing instrument for domestic and foreign were compared and analyzed from the standard applicable scope, test conditions, test items and test methods. The results can provide the reference and basis for users to select the standards and testing methods according to the testing requirements.
