Description
The Reference Test Panel No. 2 is an austenitic plate, which is chrome-plated and provided with four fields (25 x 35 mm) of different surface roughness (Ra = 2,5 μm, Ra = 5 μm, Ra = 10 μm and Ra = 15 μm) on the one half and 5 star-shaped crack patterns of different sizes on the other half. The rough fields are used for control of intermediate cleaning. The star-shaped cracks in the chrome plating are generated by ball stamping from the rear side.
The indication on the reference test panel gives no suggestion of the indication on the part under test.
