ASTM E830-87(1996)

Standard Test Method for Ash in the Analysis Sample of Refuse-Derived Fuel

SCOPE
1.1 This test method covers determination of the ash content in the analysis sample of refuse-derived fuel (RDF). The results obtained can be applied as the weight percent ash in the proximate analysis and in the ultimate analysis.  
1.2 The values stated in acceptable metric units are to be regarded as standard. The values given in parentheses are for information only.  
1.3 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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. For specific precautionary statements see Section 6.
