1.1. This test method covers the determination of total fluorine and chlorine in coal. Samples containing 10 to 5000 mg/kg of the interested analyte can be analyzed directly. Greater analyte concentrations can be determined by reducing the amount of sample combusted or increasing the volume of capture solution. 1.2. The values stated in SI units are to be regarded as standard. 1.3. In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E 29. 1.4. 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.
The purpose of this test method is to determine total Fluorine and Chlorine in coal. The chlorine content of coals may be useful in the evaluation of slagging problems and corrosion in engineering processes. Fluorine content is useful in the evaluation of fluorine emissions from coal combustion or conversion processes and can be used for compliance determinations when acceptable to a regulatory authority using performance based criteria.
