Thirteen digital reference images, previously only available as reference radiographs (ASTM E155), are now available in a digitized format.

The images illustrate the types and degrees of discontinuities that may be found in aluminum-alloy castings. This 2 DVD set consists of the 13 digital files, software to load the desired format, and specific instructions on the loading process.

One DVD provides seven digital images of 1/4 inch (6.35 mm) castings; and the second DVD provides six digital images of 3/4 inch (19.1 mm) castings. These images illustrate eight grades of severity and contain an image of a step wedge and two line pair gages.
