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



These reference radiographs for heavy-walled steel castings are applicable to nominal section thicknesses of 4-1/2 to 12 in. ( 114 to 305 mm) and consist of two sets as follows:



RRE028002 — (Volume II): 4-MV to 30 MVX Rays.



Each volume consists of three categories of graded discontinuities in increasing levels of severity, and three categories of ungraded discontinuities furnished as examples only.



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



These reference radioagraphs are also available:



RRE028001 Volume I



RRE0280CS Save when you buy the two-volume set.
