In parallel tests conducted with six coals in the adiabatic oven and in a static oxygen adsorption test in sealed flasks, the U.S. Bureau of Mines determined that the sealed-flask test can be used reliably to evaluate self-heating tendencies of coals. A field unit was constructed and is being evaluated. Statistical analysis of the data from the parallel tests resulted in a formula that predicts the minimum self-heating temperature of a coal from the total pressure change in the sealed flask during the 7-day test period.
