By organizing the severity levels (1 through 5), differentiating gas from shrinkage porosity, and creating a searchable, high-contrast reference, you reduce interpretation errors, speed up inspection times, and ensure consistent acceptance decisions.
However, finding a clean, organized, and usable version of the documentation—often referred to as an —has historically been a challenge. Raw PDFs from standards bodies can be dense, unsearchable, or cluttered with legalese.
Introduction In the world of non-destructive testing (NDT) and casting inspection, few standards are as critical as ASTM E155 . This standard governs the reference radiographs for inspection of aluminum and magnesium castings. For quality assurance managers, NDT technicians, and foundry engineers, understanding the specific porosity levels defined by this standard is non-negotiable.
