Making the grade on abrasives

FEPA products are sometimes called P grade because that letter prefixes the grit number on the back of the sandpaper as shown at right If there s no prefix you can assume that it s a CAMI-graded product As you can see in the chart at right particle sizes in the two systems closely paral-lel each other up to about 220 grit then FEPA...
