ASTM D6722-01(2006) - 1.4.2006

Significance and Use

The emission of mercury during coal combustion can be an environmental concern.

When representative test portions are analyzed according to this procedure, the total mercury is representative of concentrations in the sample.

1. Scope

1.1 These test methods cover procedures to determine the total mercury content in a sample of coal or coal combustion residue.

1.2 The values stated in SI units are regarded as the standard.

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.
