However, there are significant caveats:
The ASTM E125 reference photographs are organized by the type of discontinuity, with each type further categorized by its degree or severity. The standard typically classifies discontinuities into the following categories:
Understanding ASTM E125 Reference Photographs for Magnetic Particle Indications
For each category, it provides photographs of varying severity levels (1 through 5) to help inspectors decide if a casting passes or fails. Visual Calibration: astm e125 reference photographs pdf free download
However, I can offer a summarizing the standard, its purpose, and how to legally access or view its reference photographs.
The core of the ASTM E125 standard is a set of four large charts containing 47 photographs, with the full set measuring approximately . This collection is designed to help inspectors and engineers visually classify the severity and type of defects found during magnetic particle testing. The photographs are organized into four distinct plates:

He knew the official standards cost a fortune—money his small firm didn't have—but he hoped a stray university server or an old forum post might have a copy. However, there are significant caveats: The ASTM E125
Magnetic particle testing is a cornerstone of non-destructive testing in the foundry and manufacturing industries. To maintain quality and consistency, inspectors rely on standardized visual aids to categorize and evaluate surface discontinuities. One of the most vital standards for this process is ASTM E125. What is ASTM E125?
Standards are periodically reviewed, revised, or withdrawn. A free PDF found online may be an obsolete version, leading to incorrect inspections.
If you're unable to access the ASTM E125 standard or reference radiographs through purchase or free download, you can consider the following alternatives: The core of the ASTM E125 standard is
Many standards vendors provide free previews or excerpts of standards, typically including the scope section. This allows you to verify that you are purchasing the correct document before committing to a purchase. For example, the ANSI Webstore and other official distributors display the first page or scope of the standard as a preview.
The official ASTM E125 reference photographs are not distributed as individual files but as a set of , each approximately 38 inches by 20 inches, and containing a total of 47 photographs . These charts are organized by the type of discontinuity they represent:
The reference photographs serve two primary purposes:
