Historical (view previous versions of standard)
Significance and Use
Coal contains several elements whose individual concentrations are generally less than 0.01 %. These elements are commonly and collectively referred to as trace elements. These elements primarily occur as part of the mineral matter in coal. The potential release of certain trace elements from coal combustion sources has become an environmental concern.
The ash prepared in accordance with these provisional test methods quantitatively retains the elements listed in 1.1 and is representative of their concentrations in the coal or coke.
1.1 These test methods pertain to the determination of antimony, arsenic, beryllium, cadmium, chromium, cobalt, copper, lead, manganese, molybdenum, nickel, vanadium, and zinc in coal and coke. These test methods can also be used for the analysis of residues from coal combustion processes.
Note 1—These test methods may be applicable to the determination of other trace elements.
1.2 The values stated in SI units shall be regarded as the standard.
1.3 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.
