Your report must state: "Evaluated per ASTM E155, porosity type fine, severity Level 2 maximum observed, thickness range 0.5-1.0 inch – meets Class B requirements."

Provide side-by-side visual aids on the factory floor so NDT technicians can easily compare real-time X-ray results against accepted limits. astm e155 porosity levels pdf repack

Radiography (X-ray) is excellent for detecting macroscopic gas holes and shrinkage. However, microporosity—microscopic voids between metal dendrites—can sometimes slip past a standard X-ray. For highly stressed aerospace parts, engineers often combine ASTM E155 radiographic testing with destructive metallographic evaluations. Your report must state: "Evaluated per ASTM E155,

Immediate visualization of what a "Level 3" porosity looks like compared to a "Level 5." porosity type fine

Using Level 1 as "zero porosity." Fix: Level 1 still has some porosity. Zero porosity is a separate requirement.
