Abrasion Resistance of Dense Shaped Refractory Products - Test Method - BS EN 993-20:2004
Methods of test for dense shaped refractory products. Determination of resistance to abrasion at ambient temperature.
Resistance to Abrasion
Resistance of refractory test pieces to the surface wear caused by the mechanical action of moving solids.
This provides an indication of the suitability of the material for service in abrasive or erosive conditions.
The method determines the volume of material abraded from a flat surface of a test piece placed at right angles to a nozzle through which 1000g of size-graded silicon carbide is blasted by compressed air at 450 kPa.
