ASTM D5373-21

Standard Test Methods for Determination of Carbon, Hydrogen and Nitrogen in Analysis Samples of Coal and Carbon in Analysis Samples of Coal and Coke

SIGNIFICANCE AND USE
5.1 Carbon and hydrogen values can be used to determine the amount of oxygen (air) required in combustion processes and for calculation of the efficiency of combustion processes.  
5.2 Carbon and hydrogen determinations can be used in calculations including material balance, reactivity and yields of products relevant to coal conversion processes such as gasification and liquefaction.  
5.3 Carbon and nitrogen values can be used in material balance calculations employed for emission accounting purposes.
Note 2: The bulk composition of coal changes at a rate that varies from coal to coal during storage. As a result, using coal for calibration can yield incorrect estimates of carbon, and hydrogen content in particular.
SCOPE
1.1 Test Method A covers the determination of carbon in the range of 54.9 % to 84.7 %, hydrogen in the range of 3.26 % to 5.08 %, and nitrogen in the range of 0.57 % to 1.76 % in analysis samples (8.1) of coal and of carbon in analysis samples of coke in the range of 86.6 % to 97.9 %.  
1.1.1 Test Method B covers the determination of carbon in analysis samples of coal in the range of 57.7 % to 84.0 %, and carbon in analysis samples of coke in the range of 86.3 % to 95.4 %.
Note 1: The coals included in the interlaboratory studies employed to derive the precision statements for this standard cover ASTM rank lignite A to low volatile bituminous. Additional information concerning the composition of these coals appears in Annex A4 and Annex A5. The cokes used in the interlaboratory study employed to derive the precision statement for coke for Method A included five each metallurgical (met) cokes and seven each petroleum (pet) cokes, and Method B included an equal number (five each) of met cokes and pet cokes.  
1.2 All percentages are percent mass fractions unless otherwise noted.  
1.3 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
