Significance and Use
4.1 The calculations of analytical data for the coal and coke test parameters listed in Section 6, assume the analysis sample has been prepared according to Practice D2013 and Test Method D3302.
4.2 This practice provides formulas, to enable calculations of data from the as-determined analysis sample to various moisture bases, in common use by the coal and coke industry.
4.3 This practice provides guidance to enable calculations of weight-average data from various lots or sublots, which, initially, are provided at different moisture bases.
4.4 The principles given in this practice are applicable to the calculation of cumulative data (e.g., for trade purposes or for sieve analyses or washability analyses).
Scope
1.1 This practice lists formulas that allow analytical data to be expressed in various bases in common use. Such bases are: as received, dry, equilibrium moisture, 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 this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
