The Ultimate Guide to ASTM E125 Reference Photographs for Magnetic Particle Indications
: Available from ASTM as four large charts (Order ADJE0125) specifically arranged for each type of discontinuity.
This category covers indications found in or adjacent to repair welds, such as weld cracks, lack of fusion, or undercut. Category VII: False Indications
: The inspector compares the actual indications found on the casting (as shown by the powder) with the ASTM E125 reference photographs .
Older PDFs (e.g., 1963, 1986, 2002) are circulating online. ASTM E125 was significantly updated in 2018 and reaffirmed in 2023 . Astm E125 Reference Photographs Pdf
Porosity is caused by gas trapped in the metal during solidification. It displays as rounded, small, scattered indications across the casting surface. How to Use ASTM E125 Reference Photographs
: 31 black-and-white prints mounted on 8.5 x 11-inch cards, specifically designed for side-by-side comparison with actual castings. Digital Image Set
To standardize this evaluation process, the American Society for Testing and Materials (ASTM) developed . This article provides a comprehensive overview of the ASTM E125 standard, its categorization system, and how industry professionals utilize these reference photographs to ensure structural integrity. What is ASTM E125?
ASTM E125 is a critical standard used in nondestructive testing (NDT) to evaluate surface and near-surface discontinuities in iron and steel castings. The standard relies on a set of reference photographs to provide inspectors, engineers, and manufacturers with a visual baseline for grading the severity of various defects. The Ultimate Guide to ASTM E125 Reference Photographs
The actual reference images are high-resolution plates. Digital PDFs often lack the clarity and precise scale required for an accurate inspection. For certified industrial applications, most quality manuals require the use of the original, high-resolution physical plates or official digital media purchased directly from ASTM International.

When procuring this standard for an NDT laboratory or quality control department, always ensure you are purchasing the official ASTM adjunct package that includes the verified reference image plates. Summary of Benefits
The , officially titled Standard Reference Photographs for Magnetic Particle Indications on Ferrous Castings , is an essential tool in the nondestructive testing (NDT) industry. It provides a standardized set of visual references to assess the severity of discontinuities found on the surface of ferrous castings during dry powder magnetic particle inspection.
– Focuses on casting-specific artifacts and welding-related indications. Plate 4: False Indications and Magnetic Anomalies
: Used when a specific severity class is agreed upon between a manufacturer and purchaser to determine if a casting is acceptable. iTeh Standards Classification of Discontinuities
