Based upon the typical pressure vessel material 245R, with fracture mechanics assessment methods stipulated in GB/T 19624, assessment for safety reserve factorwas done for acceptance criteria of non-spherical defects found during the periodical inspection, the result indicated that part of acceptance criteria in the standard is not conservative enough, related revisions for acceptance criteria were given by author.
