Astm E125 Reference Photographs Pdf (2027)
ASTM E125 is a standard guide used in nondestructive testing (NDT) to identify surface and near-surface discontinuities in steel castings. It relies on a set of reference photographs that serve as a visual baseline for inspectors to evaluate the severity of defects found during magnetic particle examination. 🛠️ What is ASTM E125?
Recommendation
- Buy only from ASTM or authorized resellers (IHS, Techstreet, ANSI).
- Avoid free PDFs from file-sharing sites — they are often low-resolution, missing plates, or contain outdated severity levels.
- For training, get the PDF + printed plates if possible; for routine inspection, a high-res PDF on a calibrated monitor works fine.
- Copyright and Official Sources: ASTM International holds the copyright to these standards. Purchasing the official document from the ASTM website or authorized distributors (like Techstreet or IHS Markit) ensures you have a high-resolution, legally obtained copy.
- Image Quality: The value of ASTM E125 lies entirely in the clarity of the images. Illegal or scanned PDF copies often suffer from resolution loss, compression artifacts, or poor contrast. In NDT, a blurry reference photo can lead to misclassification of a defect, which poses safety and liability risks.
- Obsolescence: ASTM standards are periodically revised or withdrawn. While E125 is a long-standing visual standard, ensuring you have the most current edition (or the one specified by your client’s code) is essential. The last major designation was ASTM E125-63 (2023), reapproved in 2023.
- Go to ASTM.org and purchase the latest E125-18(2023) PDF.
- Store the PDF on a secure, backed-up server.
- Calibrate your inspection monitor.
- Train your team on the specific plate degrees.

Severity Levels: Level 1 represents the least severe indication, while Level 5 is the most severe. ASTM E125 is a standard guide used in
- Evaluating the quality of steel castings
- Comparing radiographic films of castings to the reference radiographs
- Determining the acceptability of castings based on the type and severity of discontinuities present
The standard is typically available in two parts: the text-based standard (PDF) and the high-resolution photographic adjuncts. ASTM International Buy only from ASTM or authorized resellers (IHS,
- Visual Inspection: Examine the casting with the naked eye (or low-power magnifier, usually 10x or less, as specified by your drawing notes).
- Identify the Defect Type: Look at the casting and determine if the issue is porosity, shrinkage, or a crack. Find the corresponding section in the ASTM E125 plates.
- Compare: Hold the casting (or a high-res photo of the area) next to the reference photographs.
- Determine the Grade: Find the photo that most closely matches the density and frequency of the defect on your part.
- Consult the Specs: Check your engineering drawing or purchase order. It will usually state: "Surface defects per ASTM E125, Grade 3 maximum." If your part is a Grade 4, it is a reject.
