Description

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.
