1.1 This test method describes a procedure for the determination of water soluble sodium as sodium oxide (Na 2 O) and potassium as potassium oxide (K 2 O) in the analysis of coal samples prepared in accordance with Practice D2013 . 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 1.3 This test method is derived in part from the ASME procedure water soluble alkalis. 2 1.4 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. 1.5 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. ====== Significance And Use ====== 5.1 Results obtained from the test method are used to serve a number of interests, including the indication of possible boiler tube fouling and possible furnace corrosion problems.
