    Significance and Use

    5.1 This test method covers the measurement of the chlorine and fluorine contents in coal. These halides can contribute to emissions with some undesirable environmental consequences.

    1. Scope

    1.1 This test method covers the determination of total fluorine and total chlorine in coal. Samples containing 200 mg/kg to 4000 mg/kg of chlorine and 20 mg/kg to 100 mg/kg of fluorine can be analyzed directly.

    1.1.1 It is possible for this method to be used for the determination of total bromine in coal. No precision and bias statement will be given for the determination of total bromine.

    1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.

    1.3 In determining the conformation of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method from Practice E29.

    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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
