4. Summary of Test Methods
4.1 In Method A, carbon, hydrogen, and nitrogen in coal or carbon in coke are determined concurrently in a single instrumental
procedure using a furnace operating at temperatures in the range of 900 °C to 1050°C. 900 °C to 1050 °C for carbon, hydrogen
and nitrogen in coal or 950 °C to 1150 °C for carbon in coke. The quantitative conversion of the carbon, hydrogen, and nitrogen
into their corresponding gases (CO , H O, and NO ) occurs during combustion of the sample at an elevated temperature in an
