Coated abrasives — Grain size analysis — Part 3: Determination of grain size distribution of microgrits P240 to P2500

ISO 6344:2013 specifies a method for determining or testing the grain size distribution of electro-fused aluminium oxide and silicon carbide microgrits P240 to P2500 for coated abrasives as defined in ISO 6344-1.

It applies both to those grits used in the manufacture of coated abrasive products and to those grits taken from products for testing purposes.
