The TAM Panel is a stainless steel plate. Half of the test surface is hard coated. Five crack centers
are evenly spaced in the hard coated strip. The crack centers are circular patterns forming a star.
The unplated portion of the TAM panel has been grit blasted to a uniform surface roughness ideally
suitable for evaluating residual penetrant background characteristics. Ra = 1,5 μm (1.5 μm).
