ASTM D5987-96(2007)
(Test Method)Standard Test Method for Total Fluorine in Coal and Coke by Pyrohydrolytic Extraction and Ion Selective Electrode or Ion Chromatograph Methods
Standard Test Method for Total Fluorine in Coal and Coke by Pyrohydrolytic Extraction and Ion Selective Electrode or Ion Chromatograph Methods
SIGNIFICANCE AND USE
This test method permits measurement of the fluorine content of coal and coke for the evaluation of potential fluorine emission from coal combustion or conversion processes. When coal samples are combusted in accordance with this test method, the fluorine is quantitatively released from the coal and retained in the pyrohydrolysate so that it is representative of the total fluorine concentration in coal.
SCOPE
1.1 This test method covers the analysis of total fluorine in coal and coke.
1.2 This analysis was successfully tested on coals containing 37 % ash or less (see AS 1038.10.4 and Conrad).
1.3 The values stated in SI units shall be regarded as standard. The values given in parentheses are for information only.
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. For specific hazard statements see Note 0.
1.4 All accountability and quality control aspects of Guide D 4621 apply to this test method.
