2. Abundance and forms of sulfur in coal. The sulfur content in coals varies considerably but is most commonly within the range of 0.5% to 5% total sulfur. The coal with less than 1% sulfur is classified as low-sulfur coal. Coal with 1% to < 3% sulfur is medium-sulfur coal. Coal with ≥ 3% sulfur is high-sulfur coal.

The standard deviation of the mean for 100 readings in a single coal should be about 0.01% to 0.02% (ICCP, 1971, and ISO 7404/5, 1994b), but this may vary slightly as a function of the coal rank. The repeatability and the reproducibility of the analyses are about 0.06% and 0.08%, respectively (ISO 7404/5, 1994b).
