This standard specifies the method for determining the resistance of dense refractory materials to abrasion and erosion at room temperature. The core of the standard involves the use of a specific abrasion testing machine, which employs compressed air to vertically project silicon carbide sand of specified particle size as the abrasive medium from a fixed height onto the surface of the test specimen. The abrasion resistance is quantified by measuring the volume of material worn away from the specimen. The standard comprehensively covers the terminology and definitions of the test, the construction of the equipment (including the blowing device, feeding system, and test chamber), specimen requirements, detailed operational procedures, methods for calculating results, and requirements for equipment inspection and calibration. It is applicable for evaluating the performance of refractory materials used in industrial abrasion environments.
