Reference Radiographs are nondestructive testing standards universally accepted because of their high reliability in accept-reject actions.



These reference radiographs consist of two volumes. Volume I consists of seventeen reference images applicable to a wall thickness of up to 1 in. (0 to 25.4 mm). Volume II consists of eight reference images applicable to a wall thickness of over 1 in. to 2 in. (25.4 mm to 50.8 mm). The images illustrate the types and degrees of discontinuities that may be found in titanium castings.



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