The standard includes photographs of different surface conditions, including:
The standard breaks discontinuities down into several specific classifications, generally including: Linear Discontinuities (such as hot tears and cracks) Inclusions Internal Chills and Unfused Chaplets False Indications and Magnetic Anomalies Why the Term "Free Download" is a Massive Red Flag astm e125 reference photographs pdf free download
— Standard Reference Photographs for Liquid Penetrant Inspection, covering similar visual reference needs for a different NDT method. Each discontinuity type must be evaluated based on
A critical note from ASTM E125 is that there is no correlation between the degrees of different defect types. For example, a "Degree 3" of Type I (Linear Discontinuities) is equivalent in severity to a "Degree 3" of Type II (Shrinkage). Each discontinuity type must be evaluated based on its own scale and the specific acceptance criteria agreed upon by the manufacturer and the purchaser. astm e125 reference photographs pdf free download
