Organization: ASTM International
Publication Date: 10 September 1998
Status: inactive
Page Count: 5
ICS Code (Solid fuels): 75.160.10
scope:

1.1 These instrumental test methods cover the determination of moisture, volatile matter, and ash, and the calculation of fixed carbon in the analysis of coal and coke samples prepared in accordance with Method D2013 and Practice D346. Results obtained through the use of the instrumental tests have been shown to differ from those obtained with Test Methods D3173, D3174, and D3175 on some coals and cokes. Where a relative bias between the instrumental methods and Test Methods D3173, D3174, and D3175 for proximate analysis of coal and coke are shown to exist, the instrumental results shall be corrected or the instrument calibrated using samples of known proximate analysis. Test Methods D3173, D3174, and D3175 shall be considered the referee test methods. The instrumental test methods are not applicable to thermogravimetric analyzers utilizing microgram size samples.

1.2 The moisture value determined is used for calculating other analytical results to a dry basis. When used in conjunction with the air dry loss moisture, as determined in accordance with Method D2013, Test Method D3302, or Practice D346, the calculated total moisture can be used to convert dry basis analytical results to the as-received basis.

1.3 The result of the ash determinations can be applied in the ultimate analysis, Practice D3176.

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 and health practices and determine the applicability of regulatory limitations prior to use.
