ASTM E155 Discontinuity Levels Guide | PDF | Materials - Scribd

. Higher severity grade numbers indicate MORE severe discontinuities. Level 8 represents the most porosity, not the least.

Non-destructive testing (NDT) in the foundry and aerospace industries relies heavily on standardized visual data to determine if a component is safe for service. Among these standards, ASTM E155 stands as the primary benchmark for inspecting aluminum and magnesium castings. astm e155 porosity levels pdf repack

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?

For digital radiography (CR/DR), the related ASTM E2422 (aluminum) or ASTM E2869 (magnesium) should be used instead of the film-based E155. Even with the best repack, you need a proper procedure

Round, distinct cavities caused by trapped gas (usually hydrogen) during solidification. Level 8 represents the most porosity, not the least

remains the benchmark for evaluating cast alloy integrity. By understanding the 8 levels of porosity and utilizing available reference materials, companies can ensure that their aluminum and magnesium castings meet the highest standards of safety and performance.

The standard identifies several specific types of internal faults:

Some guides provide estimations of defect size in mm2m m squared or diameter for various levels.

The standard reference for evaluating casting discontinuities like gas porosity in aluminum and magnesium alloys is . Quality managers, non-destructive testing (NDT) technicians, and aerospace engineers use this foundational framework to establish acceptable threshold levels for cast components.
