Significance and Use

Nitrogen results obtained by these test methods are required to fulfill the requirements of the ultimate analysis, Practice D 3176. Also, results obtained may be used to evaluate the potential formation of nitrogen oxides as a source of atmospheric pollution.

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.

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 included9 to 16
Test Method B—Kjeldahl-Gunning Semi-Micro Determination17 to 23
