This part of ISO 6344 sets forth a method for determining or testing the grain size distribution of electro-fused aluminium oxide and silicon carbide macrogrits P 12 to P 220 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 removed from products for testing purposes
