Abstract: The image obtained by FMC-TFM has better resolution, good fidelity and high SNR. Data acquisition, information processing, imaging paths, sensitivity correction, grid validation, indication identification and compensation correction are the key points of standardized operation. By interpreting the draft international standard ISO/DIS 23865:2020, the recent progress of the Full Matrix Capture (FMC) /Full Focusing Method (TFM) testing technique standardization are understood. The purpose of this paper is to provide reference for application of the advanced technology of standardized FMC-TFM for in-manufacture and in-service testing of pressure equipment at home.
