ASTM E125 Standard Reference Photographs (Adjunct ADJE0125) serve as a critical, eight-type classification system for identifying discontinuities in ferrous castings via dry powder magnetic particle inspection. The standard, which is actively maintained as E125-63(2023), provides a visual baseline for evaluating surface discontinuities, requiring agreement between manufacturers and purchasers on interpretation. Purchase options and details are available via ASTM International ASTM International

The standard also includes photographs of "Spongy" structures (rough, irregular surfaces) and "Gas holes" (smooth-walled rounded cavities). Using the digital PDF reference requires a strict protocol

ASTM E125 serves as a visual guide for the . In this method, a magnetic field is applied to a casting, and ferromagnetic particles are distributed over the surface. If a crack, inclusion, or other discontinuity exists, it disrupts the magnetic field, causing particles to cluster and form a visible "indication". The reference photographs in this standard are used to:

To use the ASTM E125 PDF effectively, you must understand the specific categories. The standard uses a letter and number system (e.g., E-1, F-2). Below is a guide to what you will see in the reference photographs. Always refer to the current, paid version of
