ASTM D8247-19 PDF Download

The total fluorine and total chlorine content of coal are tested using the ASTM D8247-19 standard. This is significant because these halides might be involved in emissions that harm the environment.

The standard includes the measurement of fluorine and chlorine concentrations in coal samples with fluorine and chlorine contents ranging from 20 mg/kg to 100 mg/kg and 200 mg/kg to 4000 mg/kg, respectively. Although no precision or bias statement is provided for bromine determination, it can also be used to determine the total amount of bromine in coal.

The rounding-off procedure described in Practice E29 should be followed in order to ensure that the findings of this test method are in compliance with any applicable specifications.
