ASTM RRE0155CS

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).

• RRE015501 -- (Volume I): The set of reference radiographs consists of 13 plates covering discontinuities in aluminum-alloy castings and 10 plates covering discontinuities in magnesium-alloy castings. Each plate is held in an 8-1/2 by 11-in. ( 216 by 279-mm) cardboard frame and each plate illustrates eight grades of severity for the discontinuity in approximately a 2 by 2-in. ( 51 by 51-mm) area. The cardboard frames are contained in a 10-1/2 by 11-1/2 in. ( 267 by 292-mm) ring binder.
  
  
• 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).
