These are indications not caused by an actual physical defect. They typically arise from magnetic writing, abrupt changes in section thickness, sharp corners, or overly high magnetizing current. How the Reference Photographs Work
You can purchase the ASTM E125 standard and the reference photographs from the ASTM website. Here's how:
: Provides actual-size photographic representations of various defect types and their severity levels. Contractual Basis
– Includes hot tears, cracks, and controlled linear separations.
The standard itself is published as a text document, but the critical reference photographs are typically provided as separate adjunct materials. Astm E125 Reference Photographs Pdf
Acquiring the official ASTM E125 standard and its reference photographs is critical for compliance. The main source is the ASTM International website, where you can purchase the current active version, ASTM E125-63(2023), as a PDF download. The standard itself is typically a 3-page document.
Magnetic Particle Testing (MT) is a cornerstone of non-destructive testing (NDT) used to detect surface and near-surface discontinuities in ferromagnetic materials. However, identifying an indication during an inspection is only half the battle; the critical next step is evaluating its severity.
Open the ASTM E125 reference catalog and compare the real-world indication against the standard photographs for that specific type.
, it’s important to understand exactly what this standard provides and why the physical reference photos are the industry gold standard. What is ASTM E125? These are indications not caused by an actual
The primary goal of ASTM E125 is to provide a "visual dictionary." Verbal descriptions of defects are often subjective. One inspector’s "slight surface pit" might be another inspector’s "moderate gas porosity."
– Foreign materials trapped in the cast, such as sand, slag, or oxides.
To standardize this evaluation process, the American Society for Testing and Materials (ASTM) developed .

Sites like Scribd host guides and partial summaries of the standard for quick reference.
The reference photographs are a comprehensive visual library covering eight distinct types of discontinuities encountered in ferrous castings, from linear defects to porosity. The latest version of these photographs is available as four large charts (ADJE0125), which together contain . The charts are organized as follows:
