To get a legitimate, high-resolution , you have three options via ASTM’s Compass portal:
The standard categorizes surface discontinuities into five distinct types of flaws. Each category contains various degrees of severity, typically ranging from linear indications to more complex formations.

The ASTM E125 reference photographs are a set of standard images that depict various types of indications and artifacts that can be encountered during magnetic particle testing. These photographs are used to evaluate the sensitivity and performance of magnetic particle testing equipment and techniques. The reference photographs are presented in a PDF format, making it easy to access and use them.
The standard designates types of discontinuities using Roman numerals I through VIII: : Linear Discontinuities (Hot tears and cracks). Type II : Shrinkage. Type III : Inclusions. Type IV : Internal Chills and Chaplets. Type V : Porosity. Type VI : Weld Discontinuities. Type VII : False Indications. Type VIII : Magnetic Anomalies. Formats and Availability

Variations in screen brightness, contrast, and color temperature can make a Type II Severity 3 defect look like a Severity 2 or 4.
Degrees of severity for each applicable discontinuity type are denoted by numbers 1 through 5, increasing in severity. A critical point to remember is that there is no correlation between the degrees of different defect types. For example, a "Degree 3" of Type I (Linear) is equivalent to a "Degree 3" of Type II (Shrinkage).
– Includes hot tears, cracks, and controlled linear separations.
