Abradability Index of Refractory Materials - Test Method - BS 1902-4.6:1985


Methods of testing refractory materials. Properties measured under an applied stress. Determination of resistance to abrasion at ambient temperature (abradability index at ambient temperature) (method 1902-406).


The abradability index represents 100 times the volume in centimetres cubed of material abraded from a test piece which has been subjected to bombardment by brown fused alumina grain for a specified time under specified conditions.


The loss in mass of a dried test piece is measured when it is subjected to the abrasive action of a specific quantity of calibrated brown fused alumina grain. The abradability index of the test piecein terms of volume loss is obtained by calculation using the measured loss in mass, a calibration correction derived from the standardization of the abrasion apparatus and alumina grain, the bulk density of the test piece and a multiplication factor of 100.
