Astm E155 Porosity Levels Pdf Repack Jun 2026
Remember: a repack does not replace the standard—it enhances its usability. Purchase the official ASTM E155, then customize your repacked PDF to match your shop floor workflow.
ASTM E155 is a standard test method for determining the porosity levels of aluminum and aluminum alloy castings. The test method involves radiographic inspection of castings to detect and classify porosity levels. This report provides an overview of the ASTM E155 standard, porosity levels, and the repack process.
ASTM E155 is organized into two volumes:
The most authoritative source is ASTM International directly. Reference radiographs for E155 inspection (Volume I) are available as adjunct RRE015501, which includes 13 plates covering discontinuities in aluminum-alloy castings and 10 plates for magnesium-alloy castings. astm e155 porosity levels pdf repack
ASTM E155 covers various types of internal flaws. The most common "porosity" categories include: ResearchGate Gas Porosity (Round):
The official ASTM E155 set consists of multiple plates, with each plate illustrating eight different severity grades for a specific discontinuity. These plates are often produced in a physical binder (10.5" x 11.5") where each plate is in a 8.5" x 11" frame.
: Typically divided into specific thickness ranges, commonly up to 2 inches (50.8 mm). Remember: a repack does not replace the standard—it
Searching for a downloadable copy of these testing materials frequently surfaces search terms like "astm e155 porosity levels pdf repack" . This occurs because industrial teams look for consolidated, digital field-guides or software-bundled references. However, using unauthorized file "repacks" introduces massive operational risks.
This comprehensive guide breaks down the core mechanics of ASTM E155 porosity levels, details the specific discontinuity categories, and outlines the compliance requirements for digital radiography. What is the ASTM E155 Standard?

Unauthorized redistribution of ASTM standards is copyright infringement. However, you can create your own personal repack legally if you purchase the standard from ASTM International or a reseller (like IHS Markit or Techstreet).
: Some distributors offer the option to purchase a printed edition of the document along with a PDF for immediate download at a package price.
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:
The process requires trained radiographic interpreters who understand not only how to match the visual appearance but also how to account for variations in casting geometry, section thickness, and radiographic technique.
