Officially titled Standard Reference Photographs for Inspection of Aluminum Alloy and Magnesium Alloy Castings , ASTM E125 is essentially a visual dictionary.
The challenge in MPT is interpreting these indications. Not all clusters of particles signify a critical defect that will cause a part to fail. To standardize the interpretation process, ASTM E125 compiles a series of actual photographs representing various types and degrees of discontinuities found in ferrous castings. These include: (such as cracks and hot tears) Shrinkage Inclusions Internal porosity
However, I can offer a summarizing the standard, its purpose, and how to legally access or view its reference photographs.
