GRIT SIZES TECHNIQUE INFORMATION

F-grit sizes bonded

Aluminium oxide & silicon carbide grains 

FEPA-Standard 42-1:2006: Grains of fused aluminium oxide, silicon carbide and other abrasive materials for bonded abrasives and for general industrial applications Macrogrits F 4 to F 220 

FEPA-Standard 42-2:2006: Grains of fused aluminium oxide, silicon carbide and other abrasive materials for bonded abrasives and for general industrial applications Microgrits F 230 to F 2000 

The mean diameters of macrogrits shown in the table are estimated and for information only, the FEPA-Standard defines them as a range and not a single value. The particle size distribution of macrogrits is determined by sieving, while the microgrits have been measured by sedimentation (photosedimentometer). 

More information can be found in the FEPA-Standards 42-1:2006 ; 42-2:2006 and in ISO 8486. Micro-F-mastergrits can be obtained from Staatliche Materialprüfungsanstalt Darmstadt

P-grit sizes coated

The mean diameters of macrogrits shown in the table are estimated and for information only, the FEPA-Standard defines them as a range and not a single value. The particle size distribution of macrogrits is determined by sieving, while the microgrits have been measured by sedimentation (US-Sedimentometer).

More information can be found in the FEPA-Standards 43-1:2006, 43-2:2006 and in ISO 6344.

Mastergrits P 12-P 220 and Mastergrits P 1500-P 2500 can be obtained from Staatliche Materialprüfungsanstalt Darmstadt

Never force the disc to stop.

Remove the disc if it is not to be used again.

Follow all the safety recommendations to avoid serious injury.In case of injury, call the emergency services.
