Eight digital reference images, previously only available as film reference radiographs (ASTM E1320 Vol. II), are now available from ASTM International. The images illustrate the types and degrees of discontinuities that may be found in titanium castings over 1 inch (25.4 mm) to 2 inches (50.8 mm). This DVD consists of the 8 digital files, software to load the desired format, and specific instructions on the loading process. The disk includes the install program, and files illustrating five discontinuity types. The graded series each illustrate eight grades of severity. 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 from 20 microns to 400 microns. A copy of the current ASTM standard is included with the purchase of these reference radiographs.
