Blast Surface Roughness Comparison Plate
It is used to evaluate the roughness of metal surfaces treated with grit blast and shot blast.
The comparison plate is divided into four stages of different roughness, and the roughness of the inspection target surface is visually or magnifying glass confirmed through the hole in the center of the comparison plate to evaluate the blast roughness. It is used for the evaluation method of blast surfaces specified in ISO 8503-1 and JIS Z 0313. There are comparison plates for grit blasting (G) and shot blasting (S). The surface roughness for grit blasting is 25, 60, 100, and 150 μm, while for shot blasting, it is 25, 40, 70, and 100 μm.
