Abstract
The current development situation of domestic X-ray measuring technique of residual stress was analyzed. Based on in-depth understanding of EU standard EN 15305-2008, some key issues of new version of GB/T 7704 were expounded, and the necessity, rationality and feasibility were also set forth. The purpose was to help X-ray measuring testers understand and carry out the standard correctly, and provide the necessary theoretical guidance and technical support to get the reliable testing results.
