ASTM D6722 Standard Test Method for Total Mercury in Coal and Coal Combustion Residues by Direct Combustion Analysis
ASTM D6722直接燃烧分析法测量煤和煤燃烧残余物中总汞量的标准试验方法
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 to be regarded as standard. No other units of measurement are included in this standard.
1.3 Warning—Mercury has been designated by EPA and many state agencies as a hazardous material that can cause central nervous system, kidney, and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury-containing products. See the applicable product Material Safety Data Sheet (MSDS) for details and EPA’s website (http://www.epa.gov/mercury/faq.htm) for additional information. Users should be aware that selling mercury or mercury-containing products, or both, in your state may be prohibited by state law.
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 and health practices and determine the applicability of regulatory limitations prior to use.
