Various potential sources of error in the ASTM C-704 abrasion resistance test method were investigated using a high performance monolithic refractory for the test samples. The results were analyzed to determine which factors caused significant variations in the abrasion loss values. Major sources of variability were: (1) age of the blasting gun, (2) trigger pull mechanism on the blasting gun, (3) position of the glass tube nozzle with respect to the air-generator nozzle, (4) seal around the glass tube nozzle, and (5) time between the weighings of the sample before and after testing. Modifications to the test method are suggested to reduce or eliminate these potential sources of error.
