Astm E155 Porosity Levels Pdf Repack Updated -

As shown, different defect types within the same casting may be assigned different allowable severity levels depending on component function and service conditions. The acceptance conditions for cast parts exceeding 19 mm wall thickness must be specified separately in the order, drawing, or test instructions.

ASTM E155 covers various types of internal flaws. The most common "porosity" categories include: ResearchGate Gas Porosity (Round):

: Entrained foreign matter, such as dross, slag, or oxide film, which can appear more or less dense than the surrounding metal depending on the material composition. Decoding ASTM E155 Porosity Levels astm e155 porosity levels pdf repack

ASTM E155 provides standardized reference radiographs for evaluating porosity and other discontinuities in aluminum and magnesium castings, with severity levels ranging from 1 (least severe) to 8 (most severe). While PDFs define the inspection criteria, the essential reference plates for comparing gas porosity and shrinkage must be obtained directly from ASTM International.

: Ensuring high-stress components like engine blocks and suspension fragments are free of catastrophic defects.

: Covers castings with thicknesses up to 2 inches (51 mm).

During an inspection, a component is assigned an acceptance criteria code based on its engineering design requirements. For example, a highly stressed aerospace bracket might require a strict "Porosity Level 2 Max," while a cosmetic or low-stress automotive cover might permit "Porosity Level 5." The Inspection Process
