Two standard gravimetric methods for the determination of total sulfur in samples of coal and coke are described. The procedures comprise the Eschka Method and the Bomb Washing Method. Both methods rely on the amount of barium sulfate precipitated after the addition of barium chloride. The analytical results are calculated to a dry basis by using the percentage of moisture found in a sample passing a number 60 (250-micron) sieve. Repeatability is within 0.05 percent for coal (under 2 percent sulfur), 0.10 percent for coal (over 2 percent sulfur), and 0.03 percent for coke. Reproducibility is within 0.10 percent for coal (under 2 percent), 0.20 percent for coal (over 2 percent sulfur), and 0.05 percent for coke.
