A: ASTM E505 covers reference radiographs for aluminum die castings only. E155 covers sand, permanent mold, and investment castings.
For digital radiography (CR/DR), the related ASTM E2422 (aluminum) or ASTM E2869 (magnesium) should be used instead of the film-based E155. astm e155 porosity levels pdf repack
