This reference is under the jurisdiction of ASTM Committee E-7 on Nondestructive Testing and is the direct responsibility of Subcommittee E07.02 on Reference Radiological Images. This includes the following: Rather than individual samples, 4 or 7 segments are created, 5x100mm each. Correspondingly, for the same criteria, the average gamma passing rate for 3D planar global gamma analysis was 95.90% ± 1.57% and 95.61% ± 1.65%.
