ASTM International Standard Digital Reference Images for Inspection of Aluminum and Magnesium Die Castings ASTM E2973-22

This standard covers digital reference images for inspection of aluminum and magnesium die castings. These digital reference images illustrate various categories, types, and severity levels of discontinuities that may occur in aluminum-alloy and magnesium-alloy die castings. They are intended to provide: a guide enabling recognition of discontinuities and their differentiation both as to type and severity level through digital radiographic imaging; and example digital radiographic illustrations of discontinuities and a nomenclature for reference in acceptance standards, specifications, and drawings. These digital reference images consist of nine images covering discontinuities in aluminum and magnesium alloy die castings. Four contain graded sequences of four levels of increasing severity in aluminum castings. Four contain graded sequences of four levels of increasing severity in magnesium castings. The last image contains ungraded illustrations of inclusions in aluminum and magnesium alloy die castings. This standard covers both graded and ungraded illustration categories. These digital reference images are not intended to illustrate the types and degrees of discontinuities found in aluminum and magnesium die castings when performing film radiography.
