Conduct a magnetic particle test on a ferrous casting according to ASTM E709 guidelines.
Use the reference photographs (often available as four large charts or "plates") to match the observed indication with a severity level. Astm E125 Reference Photographs Pdf
The standard, titled "Standard Reference Photographs for Magnetic Particle Indications on Ferrous Castings," is a critical resource in the field of Non-Destructive Testing (NDT). It provides a visual baseline for evaluating surface discontinuities in steel and other ferrous castings discovered through the magnetic particle inspection (MPI) process. What is ASTM E125? Conduct a magnetic particle test on a ferrous
ASTM E125 is a collection of reference photographs used to assist in the classification of discontinuities revealed by the . While the text of the standard itself can be purchased and downloaded as an ASTM E125 Reference Photographs PDF from ASTM International , the actual high-resolution reference images are typically provided as physical charts (Adjuncts) to ensure accuracy in scale and detail. Key Features of the Standard It provides a visual baseline for evaluating surface
Most types are categorized into five degrees of severity (1 to 5), where degree 1 represents the least severe condition and degree 5 the most. Porosity is an exception, usually showing only two degrees.
