Significance and Use
5.1 The procedure in this test method for a sample as specified herein is intended for the purpose of determining the residual moisture present in a RDF analysis sample.
5.2 The residual moisture value is used to correct as-determined analysis results such as gross heating value, sulfur, and ash to dry sample basis results.
1. Scope
1.1 This test method covers the measurement of residual moisture in refuse-derived fuel (RDF) analysis samples. It is used to calculate on a dry basis other determinations performed on analysis RDF samples. It is used with 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 a sample.
Note 1: In some instances, RDF moisture may change during size-reduction steps of the RDF 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For more specific precautionary information, see Section 7.
1.4 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.
