1.1 This test method covers the determination of the relative friability of a particular size of sized coal. It affords a means of measuring the liability of coal to break into smaller pieces when subjected to repeated handling at the mine or subsequently, by the distributor or by the consumer. This test method is serviceable for ascertaining the similarity of coals in respect to friability rather than for determining values within narrow limits to emphasize their dissimilarity. This test method also may serve to indicate the relative extent to which sized coals will suffer size degradation in certain mechanical feed devices. This test method may be used for differentiating between certain ranks and grades of coal, and therefore the test method is of service for coal classification purposes. 1.2 The values stated in inch-pound units shall be regarded as the standard. Mass may be expressed in metric values. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

A properly collected face channel sample that includes the total coal bed interval provides a sample that is a representative cross section of the coal bed at the point of sampling. Channel samples are taken for subsequent testing needed for evaluation of coal quality and characterization for commercial evaluations, for planning of mining operations to maintain coal quality, for the determination of coal rank in accordance with Classification D 388, and for geologic coal resource studies. Note 18212;Because of the potential for lateral variability, a sample may not represent the quality of the coal bed at another sample point. The reliability of the data generated from channel samples is dependent on the number and spacing of the sample points and the variability of the coal characteristics in a given area. Note 28212;Sampling of the mine product for these purposes is unsatisfactory because of contamination of the product with out-of-seam material, selective mining of parts of a seam, inability to obtain samples from one or more specific locations in the mine, or other incompatibility of the purpose of sampling with the mining practice. Conversely, channel samples should not be used for evaluation of the quality of commercial shipments of the mine product, which should be sampled in accordance with Methods D 2234. 1.1 This practice describes procedures for collecting a coal sample from a channel extending from top to bottom in the face of a coal seam in a mine. 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. For specific precautionary information, see Note 2.1.3 The values stated in SI units are to be regarded as standard; inch-pound units, which are provided for information, are approximations.

The gross calorific value can be used to compute the total calorific content of the quantity of coal or coke represented by the sample for payment purposes. The gross calorific value can be used for computing the calorific value versus sulfur content to determine whether the coal meets regulatory requirements for industrial fuels. The gross calorific value can be used to evaluate the effectiveness of beneficiation processes. The gross calorific value can be required to classify coals according to Classification D 388.1.1 This test method pertains to the determination of the gross calorific value of coal and coke by either an isoperibol or adiabatic bomb calorimeter. 1.2 The values stated in SI units are to be regarded as standard.

It is intended that this practice be used to provide a sample representative of the coal from which it is collected. Because of the variability of coal and the wide variety of mechanical sampling equipment available, caution should be used in all stages of the sample collection process, the design of sampling system specifications, the equipment procurement and the acceptance testing of installed equipment. After removal from the sampling system and further preparation (Practice D 2013), the sample may be analyzed for a number of different parameters. These parameters may define the lotrsquo;value, its ability to meet specifications, its environmental impact, as well as other properties. 1.1 This practice covers procedures for the mechanical collection of a sample under Classification I-B-1 and I-B-2 (Practice D 2234) and the within-system preparation (reduction and division) of gross samples utilizing various components of the mechanical sampling system.1.2 This practice describes mechanical sampling procedures for coals (1) by size and condition of preparation (for example, mechanically cleaned coal or raw coal) and (2) by sampling characteristics.1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard.

1.1 This practice covers procedures for obtaining a manual gross sample from beneath the surface of coal in railroad cars, barges, trucks, or stockpiles. These procedures are to be used to provide gross samples for estimating the quality of the coal. The gross samples are to be crushed, divided, and further prepared for analysis in accordance with Practice D2013. 1.2 This practice provides instruction for sampling beneath the exposed surface coal to a depth of approximately 61 cm (24 in.). Collect samples at this depth to get below the surface of the material, since drying and oxidation may have occurred at, or near the surface. Changes in moisture, in particle size, and in other properties continue to occur deeper in the coal and, although not as drastic as near the surface, will cause the method to be biased. The user should review the conditions of the coal (weather conditions, prior transport, settling time, and so forth, see 8.1) so that the interested parties can agree that potential biases are not overly great or that some adjustment in specifications is warranted. Sample increments collected from the surface layer(s) of coal in railroad cars, barges, or stockpiles are classified condition ???D??? (see Practice D2234/D2234M, Increment Collection Classification). It is a good practice to require that ???details of sampling procedure shall be agreed upon in advance by all parties concerned??? whenever collection of sample increments falls under condition ???D.??? This practice offers a sampling procedure that parties may use to meet requirements of Practice D2234/D2234M for condition ???D.??? The practice does not produce samples that satisfy precision requirements of Practice D2234/D2234M general-purpose sampling, or Practice D2234/D2234M special-purpose sampling.......
