Note: The chart shows the mid-points for the size ranges for ANSI/CAMI graded paper according to ANSI standard B74:18-1996 and for FEPA graded paper according to FEPA standard 43-GB-1984. The ANSI/CAMI statandard lists SiC particles ranges up to 600 grit paper. For the grit ANSI/CAMI papers, the particles sizes come from the CAMI booklet, Coated Abrasives (1996).
* FEPA grits finer then P2500 are not standardized and are graded at the discretion of the manufacturer.
