This consolidates high‑resolution digitized versions of the porosity severity levels from ASTM E155, reorganized for clarity, rapid comparison, and NDT (non‑destructive testing) training.
The ASTM E155 standard provides a widely accepted method for determining the porosity levels of aluminum and aluminum alloy castings. The repack process provides a convenient and standardized way to package and distribute the reference radiographs used in the standard. A repack PDF provides easy access to the porosity level information and reference radiographs, making it a valuable resource for manufacturers, inspectors, and users of aluminum castings. astm e155 porosity levels pdf repack
