Причина отмены

This test method describes a procedure for the analysis of total mercury in coal.

Formerly under the jurisdiction of Committee D05 on Coal and Coke, this test method was withdrawn in September 2014. This standard is being withdrawn without replacement due to its limited use by industry.

Значение и использование

The possible emission of mercury that may be found in coal from coal combustion is an environmental concern.

When test portions are burned according to this procedure, the total mercury is quantitatively retained and is representative of concentrations in the whole coal.
