: Represented by round or elongated dark spots corresponding to minute voids distributed throughout the casting.
Low-stress areas, mountings, or bulky sections where minor cosmetic or internal porosity will not impact the safety or lifespan of the part (Allowing Level 4 to Level 5).

Provides a highly visual, cost-effective tool for training NDT (Non-Destructive Testing) Level I and Level II technicians on defect differentiation.
The levels are relative to a master set of radiographs. You do not guess. You place your production radiograph next to (or digitally overlay) the ASTM reference of the same thickness range and match the severity.
Given the keyword you are searching for, here is legitimate guidance:
Ensure your repack specifies the exact year of the standard being used (e.g., ASTM E155 - 20 ), as reference images and categories can be updated.
Appears as round or elongated dark spots. These are typically minute voids distributed throughout the entire casting.
This is why professionals search for a – a single, organized, optimized, and complete PDF package.
Try searching the physical book for “Shadowgraph vs. Actual.” You can’t. In this PDF repack, Ctrl+F finds every mention of “interference,” “density,” and “aluminum alloy 356.” The appendix (which most people ignore) becomes usable.
