Astm E125 Reference Photographs Pdf

ASTM E125

The standard provides a vital collection of reference photographs used to classify discontinuities found in ferrous castings during magnetic particle examinations. These photographs act as a visual benchmark for comparing real-world inspection results against established severity levels. Key Features of ASTM E125

Note: Severity levels are not cross-comparable; for example, Degree 3 of Type I does not imply the same risk as Degree 3 of Type II. Practical Application Control the Document: The PDF must be read-only,

  1. Control the Document: The PDF must be read-only, version-controlled, and accessible only to authorized personnel.
  2. Annual Verification: Print a high-quality copy of the reference photographs and verify the print against the digital master annually (check for fading).
  3. Training Records: Every inspector using the PDF must be trained on how to interpret ASTM E125’s specific degree classifications.

ASTM E125 is a standard published by the American Society for Testing and Materials (ASTM) that provides guidelines for magnetic particle testing. This technique is used to detect surface and near-surface discontinuities in ferromagnetic materials. The standard outlines the procedures and requirements for magnetic particle testing, including the use of reference photographs.

  1. Surface and near-surface cracks
  2. Porosity
  3. Inclusions
  4. Segregation
  5. Other types of discontinuities
