ASTM D 6349:2021

1.1 This test method covers a procedure for the analysis of the commonly determined major and minor elements in coal, coke, and solid residues from combustion of coal and coke. These residues may be laboratory ash, bottom ash, fly ash, flue gas desulfurization sludge, and other combustion process residues. Note 1: There are two interlaboratory studies associated with this test method. The first was conducted in 1997 ( RR:D05-1035) 2 and the second was conducted in 2007 ( RR:D05-1032). 3 Sulfur trioxide was only included in the 2007 study, and that study only included combustion residues derived from ash and no combustion residues derived from coke. 1.2 Units- The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.
