ISO 19579:2006规定了使用商用仪器通过高温燃烧和红外吸收测定硬煤、褐煤和褐煤总硫含量的替代方法。 该方法已被证明适用于灰分产率低于40%的煤样。

ISO 19579:2006 specifies an alternative method of determining the total sulfur content of hard coal, brown coal, and lignite by high-temperature combustion and infrared absorption using commercially available instruments. This method has been shown to be applicable to coal samples having an ash yield of less than 40 %.
