The official ASTM E125 document provides specific "degrees" of severity (1 through 5) for each type of flaw. Having the high-fidelity original is the only way to ensure your casting meets the specific safety "Grade" required by your client or regulatory body. Conclusion Having the high-fidelity original is the only way
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. Understanding ASTM E125: A Guide to Magnetic Particle
