The standard provides a visual dictionary of surface and near-surface discontinuities revealed by magnetic particle testing (MT). It establishes a common linguistic and visual baseline between foundries, testing labs, and end-user inspectors. Types of Discontinuities Documented in ASTM E125

If you are currently setting up a non-destructive testing workflow, I can help you compile related standards. Please let me know:

ASTM standards are copyrighted materials. While ASTM allows "single copies for individual use" in some educational contexts, distributing a free, full-resolution PDF of the reference photographs without a license is copyright infringement. More importantly, low-resolution scans are dangerous . If you cannot distinguish between a Level 2 shrinkage and a Level 3 shrinkage, you might reject a good part (or worse, accept a bad part).

Even with a legitimate , inspectors make errors. Avoid these five common pitfalls: Astm E125 Reference Photographs Pdf

: Match the size and concentration of the live indication against the corresponding ASTM E125 reference photograph.

: Allows engineers to specify, "Surface defects must not exceed Level 2 of ASTM E125".

(Non-metallic particles trapped in the metal) Type IV: Internal Chills and Chaplets Type V: Porosity (Gas bubbles or small holes) The standard provides a visual dictionary of surface

| Standard | Material / Method | Focus | | :--- | :--- | :--- | | | Radiography (X-ray) | Aluminum & Magnesium castings | | ASTM E186 | Radiography | Heavy-walled steel castings (2-4.5 inches) | | ASTM E280 | Radiography | Heavy-walled steel castings (>4.5 inches) | | ASTM E446 | Radiography | Thin-walled steel castings | | ASTM E2422 | Digital Reference Images | General digital NDT |

is a set of standardized, high-quality photographs used to classify and evaluate the severity of surface discontinuities in castings. These photographs, which are often used in a digital or printed format (referred to as a "PDF" or "adjunct" in modern contexts), represent typical indications found through magnetic particle testing (MT).

The ASTM E125 reference document categorizes magnetic particle indications into five distinct types of inclusions and discontinuities. Each type represents a unique flaw born from the casting, cooling, or manufacturing process. Type I: Linear Discontinuities Please let me know: ASTM standards are copyrighted

ASTM E125 is a collection of reference photographs used to help NDT technicians identify and classify various types of discontinuities found in ferrous castings using Magnetic Particle Inspection (MPI)

Conduct regular training sessions with inspectors to calibrate their eyes against the official reference photographs, minimizing subjective variance in grading.

Finding specific sections, cross-references, or definitions takes seconds via PDF search functions.

: To enable inspectors and designers to agree upon acceptable and unacceptable levels of defects.
