ASTM E155 provides standardized reference radiographs for evaluating porosity and other discontinuities in aluminum and magnesium castings, with severity levels ranging from 1 (least severe) to 8 (most severe). While PDFs define the inspection criteria, the essential reference plates for comparing gas porosity and shrinkage must be obtained directly from ASTM International. For the official reference images and standards, visit ASTM International.
