Description of ASTM-D4326 2013ASTM D4326 - 13Standard Test Method for Major and Minor Elements in Coal and Coke Ash By X-Ray FluorescenceActive Standard ASTM D4326 | Developed by Subcommittee: D05.29 Book of Standards Volume: 05.06 ASTM D4326Significance and Use 5.1 A compositional analysis of ash is used in describing the quality of coal for its complete characterization. Ash composition is useful in predicting slagging and fouling characteristics of combusted materials as well as the potential utilization of ash by-products. 5.2 The chemical composition of laboratory prepared coal or coke ash is rarely, if ever, representative of the composition of the mineral matter in the coal because the ashing process can alter some minerals. However, it can approximate the composition of the fly ash and slag resulting from commercial combustion of coal or coke. 1. Scope 1.1 This test method covers the analysis of the commonly determined major and minor elements in ash from coal or coke using X-ray fluorescence (XRF) techniques.
Note 1 Test Method D5016 is used for determination of sulfur.
Note 2 Although not included in the present method, the determination of barium, strontium, and manganese may be
required to yield adequate totals.
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.
