Using unauthorized or heavily compressed PDF copies for final safety sign-offs can lead to critical auditing failures, loss of facility accreditation, or missed structural defects.
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."
Industrial castings must meet strict quality standards to ensure safety and structural integrity. For aluminum and magnesium castings, is the global benchmark for evaluating internal discontinuities through radiographic testing (RT). This article breaks down ASTM E155 porosity levels, inspection methodologies, and how to interpret these standards in industrial applications. What is ASTM E155?
In the world of nondestructive testing (NDT), consistency is king. When inspecting aluminum and magnesium castings for internal flaws, professionals rely on a single gold standard: . This standard governs the reference radiographs for discontinuities—specifically porosity, gas holes, and inclusions. astm e155 porosity levels pdf repack
ASTM E155 categorizes internal defects into (graded from 1 to 8). Level 1 represents the highest quality casting with minor, strictly bounded voids. Level 8 represents the highest concentration or largest allowable size of a given defect type.
A Level 3 porosity in a 0.5-inch section looks completely different than the same nominal level in a 1-inch section. Always reference the thickness-specific plate in ASTM E155.

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.
Engineers, quality inspectors, and procurement specialists frequently rely on to establish acceptance criteria, perform Non-Destructive Testing (NDT), and categorize defects. For professionals attempting to organize, distribute, or digitally repackage these guidelines (often referred to as “ASTM E155 porosity levels pdf repack”), understanding how to correctly interpret and communicate these radiographic severity levels is essential. Decoding ASTM E155: What Are Porosity Levels?
The evaluation process relies heavily on the skill of a certified Non-Destructive Testing (NDT) inspector. The workflow follows these strict engineering steps: This article breaks down ASTM E155 porosity levels,
