ASTM-D3179 › Standard Test Methods for Nitrogen in the Analysis Sample of Coal and Coke (Withdrawn 2008)
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 These test methods cover the determination of total nitrogen in samples of coal and coke. The analytical data from these test methods shall be reported as part of ultimate analysis where ultimate analysis is requested. If ultimate analysis is not requested, the value shall be reported according to the request. Two methods are included as follows:
Sections | |
Test Method A—Kjeldahl-Gunning Macro Analysis, with an alternative technique included | 9 to 16 |
Test Method B—Kjeldahl-Gunning Semi-Micro Determination | 17 to 23 |
1.2 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.
1.3 The values stated in SI units are to be regarded as the standard.
Significance and Use
Nitrogen results obtained by these test methods are required to fulfill the requirements of the ultimate analysis, Practice D 3176
Nitrogen data are used in comparing coals and in research. When the oxygen content of coal is estimated by difference, it is necessary to make a nitrogen determination.
