Understanding ASTM E155 Porosity Levels in Castings In the world of precision manufacturing, especially for automotive and aerospace components, ensuring structural integrity is critical. One of the most vital standards for this is
ASTM E155 standard
The serves as the primary benchmark for the radiographic inspection of aluminum and magnesium castings. By providing a series of reference radiographs, it allows inspectors to categorize and grade internal discontinuities, ensuring that cast components meet the rigorous safety and performance requirements of industries like aerospace and defense. What is ASTM E155?

Levels 5–8 (Lowest Quality):
High concentrations of defects. Multiple smaller defects at these levels are difficult to quantify individually. Typical Acceptance Criteria
In industries such as aerospace and automotive manufacturing, where component failure can be catastrophic, these images are not merely guidelines; they are contractual acceptance criteria. An engineer or radiographic interpreter looks at an X-ray of a physical part and compares it to the images in ASTM E155. If the porosity in the part matches "Level 4" in the standard, the part is either accepted or rejected based on that comparison. The fidelity of these images is paramount; the difference between a passing and a failing grade often comes down to subtle variations in density and contrast.

The repack process refers to the preparation and packaging of the reference radiographs used in the ASTM E155 standard. The repack process involves: What is ASTM E155
The level of porosity directly affects a part's performance. High porosity can lead to: Reduced Strength: Voids act as weak points, decreasing the ultimate tensile strength and elongation. Failure Points:
This summary document condenses the visual data you actually need for porosity grading. It breaks down the two main types of gas porosity you encounter in light alloy castings:
