Abstract：
The development and application of X-ray detection standards for aluminum alloy castings at home and abroad are summarized. By comparing the key technical requirements of each standard, the difference of quality requirements of X-ray source, diopter process and negative in the standard were analyzed, and the quality classification method was discussed emphatically. Finally, combined with the current status of X-ray detection technology, the overall situation of the standard is summarized, aiming at providing reference for the revision of relevant standards in China.
