A sand blast abrasion test apparatus is provided to prevent damage to a sensor as well as to increase in measurement accuracy by installing the sensor adjacent to a sample. A sand blast abrasion test apparatus includes a sample stage(140), a hopper, a nozzle(120), a sensor(200), and a controller. The hopper contains abrasive for abrading a sample loaded on the sample stage. The nozzle sprays the abrasive to the sample on the sample stage. The sensor detects abrasion of the sample abraded by the abrasive. The controller stops spraying the abrasive from the nozzle when the abrasion of the sample reaches a predetermined level.
