ASTM E829-23

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.

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?The values stated in SI units are to be regarded as standard. Other units of measurement in parentheses in this standard are informational.

1.5?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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
