The 8 Categories of Flaws: The standard categorizes defects into 8 distinct groups. Without the reference photos, these are just words:
What is ASTM E125?
ASTM E125, formally titled "Standard Reference Photographs for Magnetic Particle Indications on Ferrous Castings," is a document published by ASTM International. It specifically classifies the types, patterns, and severity levels of discontinuities that can be detected via magnetic particle inspection (MPI). astm e125 reference photographs pdf free download

Each category is further divided into "severity levels," typically ranging from 1 to 5. Level 1 represents the most minor or acceptable indications, while Level 5 represents the most severe. The Importance of Reference Photographs It specifically classifies the types, patterns, and severity
ASTM E125 is a collection of reference photographs used to help inspectors identify and classify various types of surface and near-surface discontinuities in ferrous castings. When performing Magnetic Particle Testing (MT), inspectors look for "indications"—patterns of magnetic particles that suggest a flaw.

Just as he was about to give up and beg his boss for the company credit card, he found an old, archived thread on a metallurgy forum from 2008. A user named 'SteelMan72' had posted a link to a digitized public domain equivalent from a decommissioned military manual. It wasn't the official ASTM PDF, but the plates—showing cracks, sand inclusions, and shrinkage—were clear enough for his preliminary assessment.
It is used primarily in Non-Destructive Testing (NDT). When inspectors perform Magnetic Particle Inspection (MPI) on ferromagnetic materials (like steel), they look for indications (flaws). ASTM E125 provides a set of photographs that classify these indications to help inspectors determine:
