Astm E155 Porosity Levels Pdf | Repack

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."

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.

⚠️ Disclaimer: This "repack" is for educational and quick-reference purposes only. For official final acceptance decisions, always consult the original, current ASTM E155 standard document and adhere to your specific contract requirements.

A very specific request!

ASTM E155 is a standard test method for "Porosity in Aluminum and Aluminum Alloy Castings." The standard provides a series of reference images and descriptions for categorizing porosity levels in aluminum and aluminum alloy castings.

The standard defines five levels of porosity, designated as Levels I to V, with Level I being the lowest and Level V being the highest. The levels are based on the size and distribution of pores within the casting.

Here is a brief summary of the porosity levels:

Level I: 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

The standard provides a detailed description of each level, along with reference radiographs (X-ray images) to help with classification. astm e155 porosity levels pdf repack

ASTM E155 Porosity Levels

The ASTM E155 standard defines four levels of porosity in steel castings, ranging from Level I (no porosity) to Level IV (severe porosity). The levels are based on the size and distribution of pores within the casting.

Porosity Levels:

Repacking and Radiography

The ASTM E155 standard also provides guidelines for repacking and radiography of steel castings. Repacking involves filling the pores with a material that allows for better radiographic interpretation. The standard recommends the following:
