(Test Method)Standard Test Method for Calculating Refuse-Derived Fuel Analysis Data from As-Determined to Different Bases
Standard Test Method for Calculating Refuse-Derived Fuel Analysis Data from As-Determined to Different Bases
SIGNIFICANCE AND USE
4.1 This test method is available to producers and users of RDF to use in converting laboratory data from one basis to another.
SCOPE
1.1 This test method gives equations to enable analytical data from the application of RDF analysis procedures to be expressed on various different bases in common use. Such bases are: as-received; dry; dry, ash-free; and others.
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.
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.
