scope:

1.1 These test methods cover the determination of total Kjeldahl nitrogen in prepared analysis samples of solid forms of refuse-derived fuel (RDF). The procedures measure free ammonia or ammonia formed from the conversion of organic nitrogenous compounds such as amino acids and proteins. However, the procedures may not convert the nitrogenous compounds of some wastes to ammonia. Examples of such compounds that may not be measured are nitro compounds, hydrozones, oxines, nitrates, semicarbazones, pyridines, and some refractory tertiary amines.

1.2 Two alternatives are described for the final determination of the ammonia, the Kjeldahl-Gunning Test Method and the Acid-Titration Test Method.

1.3 The analytical data from these test methods are to be reported as part of the ultimate analysis where ultimate analysis is requested.

1.4 These test methods may be applicable to any waste material from which a laboratory analysis sample can be prepared.

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6 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 specific precautionary statements, see 8.4.1 and Section 9.

1.7 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.
