Sets out two methods for the determination of mineral matter in coal, and a method for determination of water of constitution.

This Standard sets out two methods for the determination of mineral matter in coal, and a method for determination of water of constitution.The methods for mineral matter determination are as follows: (a) Radio-frequency oxygen plasma oxidation.(b) Air oxidation (370C).Both methods are known as low-temperature oxidation techniques. The radio-frequency method yields a residue that contains essentially the original unchanged mineral matter of the coal, and is suitable for semi-quantitative analysis of the mineral matter composition. Predictable alteration of some minerals occurs in the air oxidation process, and appropriate empirical corrections are made.For the applicability of this Standard to lower rank coals, reference should be made to Appendix A.NOTE: It is advisable to use the radio-frequency oxygen plasma oxidation method for coals of high ash, due to significant irreversible loss of water of constitution in the air oxidation method.
