ASTM E155 is the definitive standard published by ASTM International that provides standardized reference radiographs for evaluating discontinuities in aluminum-alloy and magnesium-alloy castings. Unlike a conventional written specification, ASTM E155 is fundamentally a : it consists of actual radiographic images (or digital equivalents) that illustrate various types and severity levels of casting discontinuities, allowing inspectors to compare production radiographs against graded reference standards.

The reference images illustrate different flaw categories across specific material thicknesses, typically divided into:

—and include the following porosity-related classifications: Gas Porosity (Round): Voids formed by trapped gas during solidification. Gas Porosity (Elongated):

Unofficial, high-contrast digital illustrations used for preliminary training of NDT technicians before they use the official ASTM hardware.

For specific defects like "Aluminum Foreign Material (More Dense)" at 3/4" thickness, the standard quantifies levels by area and diameter: m m squared the empty set m m squared the empty set m m squared the empty set m m squared the empty set m m squared the empty set
