A critical point that many professionals overlook is that . The standard explicitly states that these film reference radiographs are not intended to illustrate discontinuities when performing digital radiography.

is a set of radiographic plates used to evaluate internal discontinuities in castings. These reference radiographs allow inspectors to compare a casting’s X-ray image against known severity levels of defects, including: Gas porosity: Smooth-edged, spherical cavities. astm e155 porosity levels pdf repack
