Coated abrasives. Grain size analysis - Determination of grain size distribution of microgrits P240 to P2500 Ingestion-build-50790 A vapour venting performance test1 Scope This part of ISO 6344 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.
