Sets out two methods, viz. Liebig principle and high temperature method, for determining carbon and hydrogen, a method for determining nitrogen and two methods, viz. Eschka and high temperature combustion methods, for determining total sulphur in lower rank coal. Precision data are provided.

This standard sets out the method of determining the ultimate analysis of lower rank coals and char in terms of their carbon, hydrogen, nitrogen and sulphur contents.
