Reference Radiographs are nondestructive testing standards universally accepted because of their high reliability in accept-reject actions.
These reference radiographs illustrate the types and degrees of discontinuities that may be found in aluminum-alloy and magnesium-alloy castings. The castings illustrated are in thicknesses of 1/4 in. ( 6.35 mm) and 3/4 in. ( 19.1 mm).
RRE015502 (Volume II): The set of reference radiographs consists of four plates covering discontinuities in magnesium-alloy castings only. Each plate is held in an 8-1/2 by 11-in. ( 216 by 279-mm) cardboard frame and illustrates eight grades of severity for the discontinuity (with the exception of discrete discontinuities, where only one example of each discontinuity is given).
RRE015501 Volume I also available.
