If you have a specific question about determining a Grade 2 vs. Grade 3 threshold for rounded porosity on a 6mm wall thickness, drop a comment below. Let's discuss the interpretation! 👇
Having a clean, single-page visual reference (or "repack" PDF) saves massive amounts of time during First Article Inspections (FAI). Instead of flipping through 50 pages of the full ASTM volume to find the specific thickness (e.g., 1/4 inch plate) and defect type, this summary isolates the porosity charts for rapid comparison. astm e155 porosity levels pdf repack
No visible porosity Level II: Small, isolated pores (less than 1 mm in diameter) Level III: Moderate porosity, with pores up to 3 mm in diameter Level IV: Large pores, up to 6 mm in diameter, and some clusters of smaller pores Level V: Extensive porosity, with large pores (over 6 mm in diameter) and significant clustering If you have a specific question about determining
