AbstractResearchers have been working on phased array ultrasonic for about twenty years. Based on numerous studies, the basic features of PAUT have been mastered gradually. In recent years, some of the important standardization organizations, such as ISO, ASME, AWS and EN have accepted the application of phased array ultrasonic. ASTM, ISO and EN have some separate standards or drafts about PAUT. In this paper, we summarize the constitution, the fundamental contents and features of the foreign codes for PAUT, so as to provide a reference as for the application and standardization of PAUT for our country.

AbstractASTM E2491-08 provides the standard guide for evaluating performance characteristics of phased array ultrasonic testing instruments and systems. In this paper,we use the phased array technology to measure the beam focusing capability of phased array ultrasonic in direct contact condition according with ASTM E2491-08. so that we can identify the causes and effects of the focusing capability in the factors such as the number of elements and the focal depth. In the test, the block designed in ASTM E2491-08 has been used, the elements used are 8,16 and 32,and the focal depths used are 10mm,30mm,50mm,100mm,150mm and 200mm.Through the test ,we can find the focusing phenomenon clearly in the near field and we can not find this phenomenon outside the near field. When the elements used in the test increase, the focusing ability of the PAUT system increases as well. In the near field, when the focal depth increases, the focal spot size increases, too.
