DESIG: E 790 08 ^TITLE: Standard Test Method for Residual Moisture in a Refuse-Derived Fuel Analysis Sample ^SIGNUSE:

The treatment of the sample as specified herein is intended for the purpose of determining the residual moisture present in an analysis sample of RDF.

The residual moisture value is used to convert as-determined analyses such as gross heating value, sulfur, and ash to a dry sample basis.

^SCOPE:

1.1 This test method covers the measurement of the residual moisture in an analysis sample of RDF. It is used to calculate to the dry basis other determinations performed on the analysis sample. It is used with the air-dry moisture results to calculate total moisture (Note 1). The total moisture is used to calculate as-received values or other analyses performed on the sample.

Note 1 - In some instances RDF moisture may change during the size-reduction steps of the analysis sample preparation procedure. This moisture change, unless suitable corrections are made, will affect the accuracy of the total moisture value as calculated from the air-dry and residual moisture results.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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. For more specific precautionary information see Section 7.
