This International Standard specifies a method intended primarily for the determination of the abrasionresistance of shaped refractory materials at ambient temperature. It can also be used for unshaped refractorymaterials. It provides an indication of the suitability of the material for service in abrasive or erosive conditions.
NOTEThis International Standard is based on and technically identical to EN993-20, published by the EuropeanCommittee for Standardization.
