DIN ISO 6344-1:2000-04

The document sets forth definitions and grain size distribution test for electro-fused aluminium oxide and silicon carbide grits for coated abrasives, i.e. macrogrits P 12 to P 220, microgrits P 240 to P 2500. Tests for grain size distribution analysis are defined in ISO 6344-2 for macrogrits and in ISO 6344-3 for microgrits. This part of ISO 6344 applies to grits used in the manufacture of coated abrasive products and to those grits recovered from products for test purposes.
