– Foreign material trapped in the metal.

Gas holes or small voids (only two degrees of severity are provided for this type). – Non-relevant magnetic patterns

These photographs establish a universal language between foundry workers, third-party inspection agencies, and end-use customers. By comparing a live indication on a casting to the reference photographs, an inspector can determine:

Standard PDFs often compress image files. For precision NDT work, a loss of resolution can obscure fine linear indications or micro-porosity, rendering a standard PDF unreliable for formal code compliance. Gas holes or small voids (only two degrees

The inspector identifies a relevant indication on the surface.
