R10 Reference Rule (IMO's PSPC rule): To avoid insufficient coating film thickness at certain areas, such as corners, edges and weld seams in the ballast tanks, mechanical grinding of the edge area is required since stripe coatings applied on a smoother edge profile will retain liquid paints longer than the sharper shaped edge does. For this purpose, "3-Pass or 2-R" edge grinding treatment prior to secondary surface preparation is specified by IMO's PSPC rule. ----- from "Effect of edge preparation methods on edge retention rate of epoxy coatings for ship's ballast tanks" by S.S.
