Astm E155 — Porosity Levels Pdf Repack

High-volume automotive castings such as engine blocks, transmission cases, and suspension components often specify ASTM E155 porosity levels. While less stringent than aerospace requirements (typically Level 3–5), consistent application of the standard helps maintain quality control across millions of castings.

: The casting is radiographed using established radiographic techniques (typically following ASTM E94 guidelines).

Debris like dross or slag that is less dense than the base metal, appearing as irregular dark shapes.

, ranging from Level 1 (minor/hardly detectable) to Level 8 (highly porous/gross defects). www.qgdigitalpublishing.com Severity Level Characteristic Typical Use Case Smallest detectable voids; "pristine" quality. Critical, thin-walled aerospace components. Levels 2-3 Increasing size and density of voids. Standard automotive structural parts. Levels 4-7 Significant porosity; difficult to quantify precisely. Non-structural or high-mass parts. Gross porosity; highest level of discontinuity. Generally rejected for most industrial applications. Categories of Porosity and Defects Critical, thin-walled aerospace components

: Represented by round or elongated dark spots corresponding to minute voids distributed throughout the casting.

Similar to round porosity but with a stretched or oval appearance. Gas Holes: Levels 4-7 Significant porosity
