The reference photographs in ASTM E125 are divided into specific categories based on the type of defect observed during magnetic particle testing (MPT):
, is a collection of images used to classify and evaluate surface discontinuities in steel and other ferrous castings. These photographs provide a visual benchmark for inspectors using the dry powder magnetic particle method Why You Can’t Just "Download" the Reference Images It is important to clarify that while you can download the written standard text (which describes the procedure), the actual reference photographs

Furthermore, these "free" downloads often present significant risks:
The ASTM E125 standard is crucial for ensuring the structural integrity of cast products. It provides a common language for inspectors and suppliers. The reference photographs in ASTM E125 are divided

Use adequate blacklight (UV-A) intensity if using fluorescent particles. — Uploaded documents may be superseded versions
The entire point of ASTM E125 is the visual assessment of high-resolution photographs. Photocopies or heavily compressed, low-resolution PDFs found on file-sharing sites often blur the fine details of the magnetic particle indications. Using a degraded image to grade a real-world defect could lead to a massive failure in quality control. Malware Risks:
is a set of standardized photographs used to identify and classify discontinuities (defects) found during dry powder magnetic particle inspection on ferrous castings, such as steel, iron, and alloy castings.
