Methods for analysis and testing of coal and coke. Ultimate analysis of coal and coke. Determination of carbon and hydrogen content -- High temperature combustion method
This International Standard specifies a method of determining the total carbon and the total hydrogen in hard coal, brown coal and lignite, and coke, by a high temperature combustion method.
The results include the carbon in the carbonates and the hydrogen combined in the moisture and in the water of constitution of silicates.
A determination of moisture is carried out at the same time, and an appropriate correction is applied to the hydrogen value obtained by combustion.
A determination of carbon dioxide may also be made and the total carbon value corrected for the presence of mineral carbonates.
