Abstract: Taking the main line of sections structure in JB/T 4730.2—2005 as the subject and referring to relevant radiographic testing standards around the world, the article should consider contents in the relevant sections which need to be modified. Through further integrating the engineering practice and considering requirements of the special testing process and improvement of radiographic quality, the modifications could be made by supplementing and deleting, and at the same time detailed explanations and descriptions for the contents to be modified should be given.
