ASTM E897

Volatile Matter in the Analysis Sample of Refuse-Derived Fuel

Applicability: ASTM E897 applies to the analysis sample of refuse-derived fuel (RDF) produced from processed municipal solid waste (MSW) and reduced to laboratory analysis size from bulk samples collected in accordance with applicable ASTM sampling practices. It covers RDF in processed forms including fluffed material (RDF-3) with a range of organic and waste component compositions. The method determines volatile matter released during controlled high-temperature pyrolysis of the dried analysis sample.

Purpose: ASTM E897 determines the volatile matter content of a refuse-derived fuel analysis sample by heating a weighed portion in a covered crucible under rigidly controlled temperature and time conditions and calculating the loss in mass, exclusive of moisture, as a percentage of the dry sample weight. Volatile matter is a key proximate analysis parameter for characterizing RDF fuel quality, estimating combustion behavior and flame stability in waste-to-energy boilers, and comparing the energy potential of RDF materials produced from different waste streams or processing methods.
