FEPA (Fédération Européenne des Fabricants de Produits Abrasifs) Federation of European Producers of Abrasives. The FEPA distinquishes between grain for sanding paper (FEPA P) and grain for sharpening stones or wheels (FEPA F) The decisive factor for comparison is FEPA F. FEPA P is only used for sanding paper. The grit sizes are defined by the number of lines per inch (25,4 mm) length of each sieve e.g. 150 lines per inch. Abrasives grit 150 will pass this sieve. http://www.fine-tools.com/G10019.htm
