ASTM E829-16

Standard Practice for Preparing Refuse-Derived Fuel (RDF) Laboratory Samples for Analysis

SIGNIFICANCE AND USE
5.1 Using this procedure a sample of RDF can be converted into a physical form suitable for laboratory fuel analysis.  
5.2 As indicated in Test Method E791, air-dry moisture, which is determined by this procedure, is essential to the calculation of other laboratory results on an as-received basis. The air-dry moisture value is used in conjunction with the results of the residual moisture determination in Test Method E790 to calculate total sample moisture.
SCOPE
1.1 This practice covers the preparation of RDF laboratory samples for analysis, the laboratory samples having been previously obtained from representative RDF samples.  
1.2 The determination of the air-dry loss of the RDF is part of this preparation procedure and must be performed prior to the particle size reduction.  
1.3 The practice given may also be used for other RDF types but additional sample preparation steps may be necessary prior to the application of this method.  
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. Specific hazard statements are given in Section 7.
