1.1 This test method covers the instrumental the determination of carbon in the range of 54.9 % m\/m to 84.7 % m\/m, hydrogen in the range of 3.25 % m\/m to 5.10 % m\/m, and nitrogen in the range of 0.57 % m\/m to 1.80 % m\/m in the analysis sample (7.1) of coal.<\/p>\n
Note<\/span> 1The coals included in the interlaboratory study employed to derive the precision statement for this standard cover ASTM rank lignite A to low volatile bituminous. Additional information concerning the composition of these coals appears in Annex A5.<\/p>\n 1.2 The values stated in SI units shall be regarded as the standard.<\/p>\n 1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.<\/span><\/p>\n D5373-08 Standard Test Methods for Instrumental Determination of Carbon, Hydrogen, and Nitrogen in Laboratory Samples of Coal<\/b><\/p>\nPDF Catalog<\/h4>\n
