Thirteen digital reference images, previously only available as film 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.



A copy of the current ASTM standard is included with the purchase of these reference radiographs.



The images may be installed as 16-bit TIFF files or as DICONDE files and may be installed for negative or positive image polarity. The images may be installed at resolutions to match the effective resolution of various digital detectors in increments of 10 microns
