Significance and Use
5.1 The purpose of this test method is to measure the total chlorine in coal. Knowledge of the chlorine in coals may be useful in the evaluation of slagging problems, corrosion in engineering processes, and in the total analysis of coal and coke. When coal samples are combusted in accordance with this method, the chlorine is quantitatively retained and is representative of the total chlorine in the whole coal.
Scope
1.1 This test method covers the analysis of total chlorine in coal.
