1.1 This test method covers the determination of the relative grindability or ease of pulverization of coals in comparison with coals chosen as standards. A prepared and sized sample receives a definite amount of grinding energy in a miniature pulverizer, and the size consist of the pulverized product is determined by sieving. The resultant size consist is used to produce an index relative to the ease of grinding (Hardgrove Grindability Index (HGI)).1.1.1 Some coals, such as some high-volatile bituminous, subbituminous, and lignite coals, can undergo physical change as the natural or seam moisture is released during handling and preparation. This change is often sufficient to alter the grindability characteristics that will be reported when tested in the laboratory and could produce different indices dependent on the conditions of drying and the moisture level of the 1.18-mm by 600-m (No. 16 x No. 30) (see Test Method D 4749) materials used for the test. Therefore, the repeatability and reproducibility cited in this test method may not apply for these high-volatile bituminous, subbituminous, and lignite coals.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses may be approximate.1.3 It is recognized that the term weight is considered equivalent to mass as used in this test method.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.

1.1 This practice covers the reduction and division of gross or divided samples up to and including the individual portions for laboratory analysis.1.2 Reduction and division procedures are prescribed for coals of the following groups:1.2.1 Group A includes coals that have been cleaned in all sizes.1.2.2 Group B includes all other coals. Unknown coals are to be considered under Group B.1.2.3 Group A allows smaller weight laboratory samples to be retained than Group B. These lower weights may be used for particular coals if they have been shown, by using the procedures of Annex A1.2, to give a sample preparation and analysis variance which is no more than 20 % of the total analysis variance.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

The usefulness of results from this guide will vary greatly depending on such factors as top size of the coal, size consistency of the coal, variability of the coal, and such logistical factors as the flow rate of the coal in process and physical accessibility of the sampling station.1.2 This guide should be used only when it is not possible to use a method of sampling that produces a probability sample.1.3 Sample preparation procedures involving crushing are contained in Method D 2013.1.4 The values stated in SI units are to be regarded as standard.

1.1 This practice covers procedures for obtaining a manual gross sample from the surface of coal stockpiles. These procedures are used to provide gross samples for general laboratory analysis and for estimating quality and total moisture. The gross sample is to be crushed and further prepared for analysis in accordance with Method D2013. Mechanical equipment such as auger samplers and core drill rigs are addressed by othe guides (D 4916) or working papers.1.2 The user is cautioned that samples of this type do not satisfy the minimum requirements for probability sampling and as such cannot be used to draw statistical inferences about the precision, standard error, or bias. 1.3 This sampling method is intended for use only when sampling by more reliable methods that provide a probability sample is not possible.1.4 The quantities stated in either acceptable SI units or in inch-pound units are regarded separately as standard. The quantities stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining quantities in any way.1.5 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.

On-line analyzers are used to provide quality data on lots of coal. The resulting quality data are used as a production tool or for some contractual application. This guide provides means of evaluating the system and data produced. The user should become familiar with the documentrsquo;terminology and layout. The section on test design and data collection will provide the means by which all the analysis data will be gathered. The test design should be carefully considered so as to assure meeting the userrsquo;requirements. The procedures defined in this guide can be used to test the accuracy and precision of an on-line analyzer, for acceptance after its installation, to check precision and accuracy during routine use (quality control), when changes are made to the system, when the nature of the coal being tested changes, and to determine mathematical factors to be used for calibration of the on-line analyzer.1.1 This guide provides techniques to be used for the evaluation of the measurement performance of on-line coal analyzers.1.2 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.
